AI Summary
  • Moonshot AI prices two surfaces from its Kimi platform: a tempo-named consumer assistant ($0 Free to $199/mo Vivace) and a per-token developer API.
  • Kimi's per-token API spans a 15.8x range: flagship Kimi K3 (July 2026) is $3.00 input / $15.00 output per 1M tokens with a 1,048,576-token context window, while Kimi K2.6 and K2.7 Code run $0.95 in / $4.00 out, all with 262,144-token context. Kimi K2.5 (previously the cheapest model in the Kimi K-series line, $0.60 in / $3.00 out) was officially retired on 2026-08-31.
  • Moonshot pioneered context caching for LLM APIs in 2024; cache-hit input is billed 80–90% below cache-miss across every current model, the signature cost lever.
  • The legacy context-tiered moonshot-v1 API ($0.20/$2.00 at 8k up to $2.00/$5.00 at 128k) and Kimi K2.5 were officially retired on August 31, 2026 — Moonshot's own docs confirm calls to either now return a 404 (model not found) error, leaving Kimi K3, K2.7 Code and K2.6 as the only priced models.
  • API rate limits are recharge-tiered from $1 (Tier0) to $3,000 (Tier5); the K3-launch promotion that returned 10–30% of a single top-up as vouchers carried a stated 2026-08-12 end date and is no longer offered, confirmed on the 2026-09-07 recapture.
  • Kimi Business regained a public price on 2026-08-28 — a self-serve $600/year/seat plan (minimum 2 seats) via a new 'Business' tab and Subscribe checkout on kimi.com/membership/pricing — three weeks after that tier had been pulled sales-only on 2026-08-04, though the separate Kimi Business marketing page still shows only 'Contact sales' with no price.

Kimi assistant prices are USD/mo; annual billing is charged once a year and saves about 20% (up to $480/yr on Vivace). As of this capture (2026-08-28) a 'New Membership Plans Coming Soon' banner (Kimi and Kimi Code benefits will be separated; existing subscribers unaffected) has replaced every assistant/Kimi Code plan's purchase button with 'Join Waitlist'. Apple in-app-purchase price points differ slightly from the web card ($180.99 / $374.99 / $949.00 / $1,999.00 annually on iOS). API prices are USD per 1M tokens; context caching cuts input 80–90%. The legacy context-tiered moonshot-v1 family and Kimi K2.5 were officially retired on August 31, 2026 — calls to either now return a 404 (model not found) error; only Kimi K3, K2.7 Code and K2.6 remain priced (historical moonshot-v1/K2.5 rates are in Pricing evolution). Kimi Business regained a public price on 2026-08-28 — $600/year/seat with a self-serve Subscribe checkout on a new Business tab at kimi.com/membership/pricing — after its prior public per-seat/year card was pulled sales-only on 2026-08-04; the dedicated Kimi Business marketing page still shows Contact sales only.

About

Moonshot AI (月之暗面, “Dark Side of the Moon”) is a Beijing-based foundation-model company best known for Kimi, its long-context assistant, and the Kimi K2 family of open-weight models. It serves two distinct buyers: individuals and teams who subscribe to the Kimi assistant for chat, deep research, and agentic coding, and developers who call Kimi/Moonshot models over a per-token API. The company monetizes hosted inference and a managed assistant on top of weights it releases openly — a structurally similar bet to Europe’s Mistral AI, executed inside China’s brutally competitive model-price market.

Founded in March 2023 by Tsinghua schoolmates Yang Zhilin, Zhou Xinyu, and Wu Yuxin, Moonshot launched the Kimi assistant in October 2023 with a long-context hook — the first product to support 200,000-character Chinese input, later expanded to 2 million characters in a March 2024 upgrade that went viral across Chinese social media. That long-context positioning is the company’s founding differentiator and shows up directly in the price sheet: the legacy moonshot-v1 API charges by context window.

Moonshot is among China’s top-funded LLM startups, backed by Alibaba, Tencent, IDG Capital, 5Y Capital, Meituan, and China Mobile. Its valuation climbed from roughly $4.3B early on to about $10B (February 2026) and then to around $20B after raising ~$2B in May 2026 — a trajectory tied to demand for its open-weight models and a reported Hong Kong IPO targeted for the second half of 2026. The July 2025 release of Kimi K2 — a 1-trillion-parameter Mixture-of-Experts model with 32B active parameters — became the fastest-downloaded model on Hugging Face one day after launch and helped ignite an aggressive China model-price war.

In July 2026 Moonshot moved up-market with Kimi K3, a 2.8-trillion-parameter, natively multimodal flagship with a 1,048,576-token context window aimed at long-horizon coding, knowledge work, and deep reasoning. K3 carries the first genuinely premium rate card in the company’s history — $3.00 per 1M input tokens and $15.00 per 1M output — while the K2 family stays at the cheap end and the original context-tiered moonshot-v1 models, along with Kimi K2.5, were officially retired on August 31, 2026 (calls to either now return a 404 error).


Pricing summary : subscription assistant plus a cache-discounted per-model token API

Moonshot AI runs a two-track model: flat-rate freemium subscriptions for the Kimi assistant and pure usage-based pricing for the developer API, billed per million tokens. The dimensions are:

  • Kimi assistant seats — a tempo-named ladder: Free/Adagio ($0), Moderato ($19/mo), Allegretto ($39/mo), Allegro ($99/mo), Vivace ($199/mo), each with an annual option billed once a year at $180, $372, $948 and $1,908 respectively — about 20% off twelve monthly payments. As of this capture (2026-09-07), a “New Membership Plans Coming Soon” banner on the plan page still announces that Kimi and Kimi Code benefits will be separated (existing subscribers unaffected), and every tier’s purchase button still reads “Join Waitlist” instead of a direct buy CTA.
  • API tokens (Kimi K3) — the flagship, $3.00 in (cache miss) / $15.00 out per 1M, cache-hit input $0.30/M, 1,048,576-token context.
  • API tokens (Kimi K2 family) — Kimi K2.6 and Kimi K2.7 Code at $0.95 in / $4.00 out, and a K2.7 Code HighSpeed variant at exactly double ($1.90 in / $8.00 out) for ~180 tokens/s output. Kimi K2.5 was officially retired on August 31, 2026 (historical rate in Pricing evolution).
  • API tokens (moonshot-v1, context-tiered) — formerly the same model priced by context window (8k/32k/128k tiers, historical rates in Pricing evolution). Officially retired on August 31, 2026 — calls now return a 404 (model not found) error, alongside Kimi K2.5; only Kimi K3, K2.7 Code and K2.6 remain on the current price card.
  • Context caching — cache-hit prompt prefixes billed 80–90% below cache-miss input (e.g. $0.16/M vs $0.95/M on K2.6; $0.30/M vs $3.00/M on K3). Caching is automatic on every current model.
  • Recharge tiers — API rate limits scale with cumulative recharge, from Tier0 at $1 to Tier5 at $3,000; a $5 cumulative recharge earns a $5 voucher. A K3-launch rebate (10–30% of a single top-up as vouchers) was advertised through 2026-08-12, but as of this capture the dedicated promotion page no longer shows the offer — treat it as expired/withdrawn until confirmed otherwise.
  • Batch and tool meters — separate BatchJob and WebSearch rate cards sit alongside the chat-completion meter.
  • Kimi Business — a per-seat/year rate (live through 2026-07-30) was pulled from the dedicated kimi.com/zh-cn/business marketing page and moved sales-only on 2026-08-04. As of this capture (2026-09-07) the price is still public — $600/year/seat, minimum 2 seats, billed annually — via a self-serve “Business” tab and Subscribe checkout on kimi.com/membership/pricing. The standalone marketing page still shows “Contact sales” with no price, so a sales-led path and a self-serve path continue to coexist for the same tier.

What makes this different: Moonshot prices per-million-token billing publicly, but adds two China-market signatures — context-length as a price axis on the sunsetting legacy API and a deep context-caching discount it pioneered in 2024 — on top of open weights you can download and run yourself. Kimi K3 adds a third: a genuine 5× price ladder between the flagship and the K2 line, so model choice, not context length, is now the main cost lever.

Annual billing is charged once a year and saves a flat ~20% (up to $480/yr on Vivace). Agent credit counts are Moonshot’s own “approximate values based on typical task token consumption”; agent features share one credit pool while Kimi Code has a separate pool, and K2.6 usage does not consume credits. Buying the same tiers through Apple’s in-app purchase uses Apple price points that differ slightly from the web card — $180.99 / $374.99 / $949.00 / $1,999.00 per year. The original Kimi assistant launched free in October 2023 and added a viral “tipping/recharge” feature in May 2024 to buy priority during capacity crunches. As of this capture (2026-09-07), both kimi.com/membership/pricing and kimi.com/code still show a “New Membership Plans Coming Soon” banner — Kimi and Kimi Code benefits will be separated in a future release, existing subscribers unaffected — and every plan tier’s purchase button now reads “Join Waitlist” rather than a direct buy CTA, even though the banner text states the current plan can still be bought before launch.

API — Kimi K3 (flagship, per 1M tokens, USD)

ModelInput /M (cache miss)Output /MCache-hit input /MContext window
kimi-k3$3.00$15.00$0.301,048,576 tokens

K3 always reasons; reasoning depth is set per request via reasoning_effort (low / high / max, default max) with no separate reasoning-token line item. Automatic context caching, ToolCalls, JSON mode, structured output and internet search are included in the rate.

API — Kimi K2 family (per 1M tokens, USD)

ModelInput /M (cache miss)Output /MCache-hit input /MContext window
kimi-k2.7-code$0.95$4.00$0.19262,144 tokens

kimi-k2.6$0.95$4.00$0.16262,144 tokens
kimi-k2.5RETIREDRETIREDRETIREDRETIRED 2026-08-31

HighSpeed is the same model as Kimi K2.7 Code at exactly double every rate, bought purely for throughput (~180 tokens/s output, up to 260 tokens/s in short contexts). Cache-hit input is billed 80–90% below cache-miss across the family, and the K2 weights are published on Hugging Face. Kimi K2.5 was officially retired on August 31, 2026 — Moonshot’s own docs state calls to it now return a 404 (model not found) error, and it no longer appears on the live Model Pricing nav; migrate to Kimi K3 or another current model. (Its former rate is preserved in Pricing evolution.)

API — moonshot-v1 (context-length-tiered, per 1M tokens, USD) — RETIRED 2026-08-31

The -vision-preview variants of all three tiers carried identical rates. The entire moonshot-v1 family was officially retired on August 31, 2026 — Moonshot’s docs now state “Calls to these models now return a 404 (model not found) error. Please migrate to kimi-k3 or other latest models,” and the dedicated pricing sub-page (/docs/pricing/chat-v1) now redirects to the API docs’ Model List page instead of a rate card. Former per-tier rates are preserved in Pricing evolution. The legacy family priced the same model by context window — context length is literally the meter — a mechanic the Kimi K2/K3 models replaced with a single flat per-model rate.

Kimi Business (team/enterprise track)

TierPriceIncludedKey mechanics
Business (Premium)$600 / year / seat, billed for 12 months — minimum 2 seatsUp to 1M-token context; Kimi Work + Kimi Code included; parallel Swarm agents; customizable dashboard; curated plugins; dedicated technical support; business data not used for training by defaultSelf-serve — seat-quantity stepper (default shown: 5 seats) and a “Subscribe” checkout button, no sales contact required

Two distinct surfaces cover this tier as of this capture (2026-09-07, unchanged since 2026-08-28). A “Business” tab on kimi.com/membership/pricing — a page that rendered no prices to crawlers as recently as 2026-08-04 — now shows a self-serve $600/year/seat “Premium” card with a working seat stepper and Subscribe button; its own FAQ states the plan is “currently billed annually, with no promotions or discounts” and invoices (including VAT) are supported. Separately, the dedicated marketing page at kimi.com/zh-cn/business (now rendering English content despite the zh-cn URL) still shows only “Get Kimi Business” / “Contact sales” with no price or itemized feature list — the same sales-only state first observed 2026-08-04. The prior public per-seat/year card (last shown 2026-07-30, and logged in this page’s pricing history) was priced within a few dollars of the current $600 rate, so this reads as the same tier resurfacing on a new URL rather than a fresh repricing. The API’s separate “Verify Organization” track (flexible rate limits, multi-project deployments, SLA-backed reliability, dedicated support) remains sales-led with no public rate card of its own — unrelated to this Kimi Business seat plan.

Sales motions across products: PLG / self-serve for the Kimi assistant tiers, the pay-as-you-go API, and — as of this capture — Kimi Business via the membership/pricing “Business” tab ($600/yr/seat, self-serve Subscribe checkout). Recharge tiers and top-up rebates reward larger prepaid balances on the API. The dedicated Kimi Business marketing page and the API’s “Verify Organization” track (flexible rate limits, multi-project deployments, SLA-backed reliability, dedicated support) remain sales-led with no public rate card of their own.


Hidden costs : What Moonshot AI (Kimi) users actually pay

Moonshot’s headline rates are among the lowest in the market, but the real bill is shaped by three things the sticker price doesn’t show: whether your prompts actually hit the cache, which context tier you land on with the legacy API, and the output-token premium that dominates generation-heavy workloads. Two archetypes show how the total assembles.

Archetype 1 — a developer running a long-context RAG agent on Kimi K2.5. Assume ~60M input + ~15M output tokens a month, with a stable system prompt and document context that hits the cache about 60% of the time.

Line itemMonthly cost
K2.5 input — 24M cache-miss tok @ $0.60/M$14.40
K2.5 input — 36M cache-hit tok @ $0.10/M$3.60
K2.5 output — 15M tok @ $3.00/M$45.00
Estimated total~$63/mo

The lesson: cache hits collapse the input line — the 36M cached tokens cost less than $4, versus ~$21.60 if they all missed. But output is the dominant meter at $3.00/M (5× the cache-miss input rate), so generation-heavy work (long answers, code) drives the bill regardless of how well you cache.

Archetype 2 — a legacy app pinned to moonshot-v1-128k for full-document context. A team feeds whole documents into the 128k context window, running ~20M input + ~5M output tokens a month.

Line itemMonthly cost
moonshot-v1-128k input — 20M tok @ $2.00/M$40.00
moonshot-v1-128k output — 5M tok @ $5.00/M$25.00
Estimated total~$65/mo

Here the surprise is the context-tier tax: the same workload on moonshot-v1-8k would cost $0.20/$2.00 (about $14/mo), so reaching for the 128k window is a roughly 4–5× premium. The fix is usually to migrate to a Kimi K2 model, which folds long context into one flat per-model rate plus caching rather than charging an escalating context tier.

Pricing evolution : Moonshot AI pricing history and changes

Moonshot’s pricing evolved along two tracks. The Kimi assistant went from a free, long-context novelty (2023) to a tempo-named subscription ladder; the API moved from context-tiered moonshot-v1 rates (2024) to an aggressive open-weight Kimi K2 price war (2025), then its first material price increase with K2.6 (April 2026) and its first genuinely premium tier with Kimi K3 (July 2026). The dated milestones below are reconstructed from primary announcements and contemporaneous press.

Notable changes

  • 2023-10 — Kimi assistant launches free, built around 200,000-character long context (Wikipedia).
  • 2024-03 — Lossless context expands to 2,000,000 Chinese characters and goes viral; context-tiered moonshot-v1 API (8k/32k/128k) is live.
  • 2024-05 — Viral tipping/recharge feature lets users pay for priority during capacity crunches; API rate limits tier by cumulative recharge.
  • 2024-07 — Context caching pioneered, cutting cache-hit input ~80–85% below cache-miss.
  • 2025-07Kimi K2 open-weight (1T-param MoE) launches at aggressive rates and tops Hugging Face downloads, pressuring OpenAI/Anthropic on price (HPCwire).
  • 2026-02Kimi K2.5 adds vision and agent swarm at $0.60 in / $3.00 out, cache-hit input $0.10/M; top-up bonus program reinforces recharge.
  • 2026-04Kimi K2.6 raises input 58% ($0.60 to $0.95/M) and output to $4.00/M — read as a pre-IPO commercialization signal (KuCoin); legacy K2 reaches end-of-life 2026-05-25.
  • 2026-07-15 — A K3 launch top-up rebate opens through 2026-08-12: 10–30% of a single top-up returned as vouchers, capped at $4,000 and valid 90 days, on the pay-as-you-go API only.
  • 2026-07-16Kimi K3 launches at $3.00 in / $15.00 out per 1M (cache-hit input $0.30/M, 1,048,576-token context) — the first genuinely premium rate on Moonshot’s card, roughly 3.2× the input and 3.75× the output of K2.6. Kimi K2.7 Code lands at $0.95/$4.00 with a HighSpeed variant priced at exactly double ($1.90/$8.00) that buys throughput, not capability.
  • 2026-07-21 — Moonshot’s model-pricing overview flags the legacy moonshot-v1 family for “full platform sunset expected on August 31”, and the legacy Kimi K2 0711/0905/Turbo and K2 Thinking models disappear from the card entirely.
  • 2026-07-19 — Reports (Yahoo Finance and Investing.com; The Information on 2026-07-20) that Moonshot is seeking investor approval to begin a Hong Kong IPO, targeting a listing within six months of the Kimi K3 debut — moving the long-”reported” listing from backdrop to an active process. No price change accompanies the plan, but an IPO track historically ends a lab’s deepest-discount phase as margin disclosure begins, which is consistent with the direction the card has already taken: the +58% K2.6 increase and the K3 ceiling both read as pre-IPO commercialization rather than reversible promotions.
  • 2026-08-04Kimi Enterprise (Business) pulls its only public per-seat/year price card — live as recently as 2026-07-30 — from the China-site business page and moves to a sales-only motion routing to [email protected] with no disclosed rate; the Kimi assistant subscriptions and the full per-token API card are unaffected.
  • 2026-08-28Kimi Business (the renamed Kimi Enterprise tier) regains a public price after three weeks sales-only: a new “Business” tab on kimi.com/membership/pricing — a page that rendered no prices to crawlers as recently as 2026-08-04 — shows a self-serve $600/year/seat plan (minimum 2 seats) with a working seat stepper and “Subscribe” checkout, close to the pulled $599/yr/seat rate. The standalone kimi.com/zh-cn/business marketing page still shows only “Contact sales,” so a self-serve and a sales-led path now coexist for the same tier. The same capture found the Kimi assistant and Kimi Code plan pages showing a “New Membership Plans Coming Soon” banner, with every tier’s buy button switched to “Join Waitlist.”
  • 2026-08-31 — Moonshot’s own docs confirm the previously “scheduled” moonshot-v1 sunset took effect and disclose a new casualty: Kimi K2.5 — the cheapest model in the Kimi K-series line ($0.60 in / $3.00 out) and the holder of the platform’s lowest published cache-hit rate ($0.10/M) — is also officially retired the same day. Calls to either model family now return a 404 (model not found) error, and neither appears on the live Model Pricing nav (K3, K2.7 Code, K2.6, Other only).

The Kimi K2.6 price increase in detail

The April 2026 K2.6 release broke a two-year pattern of cuts. Input rose 58% from $0.60 to $0.95 per 1M tokens, output climbed to $4.00/M (21 to 27 yuan RMB), and even the cache-hit input rate ticked up (0.7 to 1.1 yuan RMB). After years of using aggressive pricing to win developer share, Moonshot raised rates on its flagship model — which observers read as deliberate proof of “commercialization capability” ahead of a reported Hong Kong listing in the second half of 2026, following competitors Zhipu and MiniMax to public markets. The strategic read: a lab that can raise prices on a leading model without losing its developer base is a more investable lab, and the open-weight escape hatch (download K2.6 yourself) blunts the backlash a closed-weight increase would trigger.

The Kimi K3 ceiling and the moonshot-v1 sunset in detail

July 2026 did to the shape of the rate card what April did to its level. Kimi K3 (2026-07-16) is priced 3.2× the input and 3.75× the output of K2.6, but nothing below it moved — K2.6, K2.5 and the new K2.7 Code all still sit at or under $0.95 in / $4.00 out. That is the difference between raising a price and adding a rung: K2.6 repriced the model everyone was already calling, while K3 asks existing workloads to opt in. The practical effect is a genuine 5× ladder where model selection, not context length, is now the primary cost lever — and the first time a Moonshot bill can plausibly run into four figures. Re-running the long-context RAG archetype from Hidden costs (60M input at a 60% cache-hit rate, 15M output) on K3 instead of K2.5 takes it from roughly $63/mo to roughly $308/mo, with output alone accounting for $225 of it.

Caching is what keeps that ladder navigable. K3’s cache-hit input is 90% below its cache-miss rate ($0.30 vs $3.00), a deeper discount than the ~83% on K2.5 and K2.6 — so a reused prompt prefix on the flagship costs only 3× what it costs on K2.5, even though a fresh one costs 5×. Moonshot has effectively made cache discipline the deciding factor in whether K3 is affordable, and mis-designed prefixes are now the single most expensive mistake on the platform.

The moonshot-v1 sunset — flagged 2026-07-21, confirmed effective 2026-08-31 — retired the mechanic that defined Moonshot’s early card: the same model priced by context window. It landed with a wrinkle the July announcement never disclosed: Kimi K2.5, the obvious same-day landing spot for displaced moonshot-v1 traffic (and the model this page’s own Hidden Costs archetype was built on), was retired on the identical date. That reshapes the migration math rather than removing it. A workload pinned to moonshot-v1-128k ($2.00/$5.00) now lands on Kimi K2.6 at $0.95/$4.00 with double the context window — still a clear cut, just to a different model than the one that was available a day earlier. A workload on moonshot-v1-8k fares worse: at $0.20 in / $2.00 out it held the cheapest input rate Moonshot ever published, and with K2.5 gone its nearest live successor is also Kimi K2.6 — a 4.75× input and 2× output increase, steeper than the 3×/1.5× jump it would have faced migrating to K2.5 the week before. The sunset therefore lifts the platform’s floor by more than the July notice signposted, on roughly a six-week clock, with still no published per-SKU migration mapping — the sharpest edge of the July changes for buyers with production traffic on legacy SKUs.


What’s unique : Moonshot AI’s distinctive pricing mechanics

1. Context length as a price axis — now retired. The legacy moonshot-v1 family charged different per-token rates for the same model depending on the context window requested — $0.20/$2.00 at 8k up to $2.00/$5.00 at 128k per 1M tokens. Most vendors charge one rate and cap context; Moonshot, whose founding differentiator was long context, turned the context window itself into a billable tier. The Kimi K2 and K3 models folded that into a single flat per-model rate, and the sunset flagged on 2026-07-21 took effect exactly on schedule on 2026-08-31 — a rare, datable example of a pricing axis being decommissioned once the product stopped needing it. The same cutover swept in an undisclosed second casualty, Kimi K2.5, without a separate announcement — a reminder that a scheduled deprecation’s blast radius isn’t always limited to the SKU named in the notice.

2. Context caching as the headline cost lever — and it deepens as the sticker rises. Moonshot pioneered context caching for LLM APIs in 2024, billing cache-hit prompt prefixes 80–90% below cache-miss. The discount is not uniform: it is ~83% on K2.5 ($0.10 vs $0.60) and K2.6, but 90% on Kimi K3 ($0.30 vs $3.00), so a reused prefix on the flagship costs only 3× the K2.5 rate while a fresh one costs 5×. For agents and RAG systems, caching — not the sticker rate — is what actually determines the bill, and Moonshot was early enough that the primitive shaped how the broader token economics market now prices repeated context.

3. Throughput sold as a flat 2× SKU. Kimi K2.7 Code HighSpeed is the same model with the same 262,144-token context, priced at exactly double every meter — $1.90 in / $8.00 out / $0.38 cache-hit versus $0.95 / $4.00 / $0.19 — and what you buy is speed (~180 tokens/s output, up to 260 in short contexts). Most vendors bury latency in an enterprise contract or a provisioned-capacity commitment; Moonshot exposes it as a model id you can switch to per request, with a doubling that needs no calculator. It is the cleanest expression yet of speed as an independently priced dimension rather than a bundled service level.

4. Open weights plus a recharge-tiered, price-war API. Kimi K2 models ship open-weight under a modified MIT license, yet Moonshot monetizes hosted inference at rates aggressive enough to pressure OpenAI and Anthropic. Layered on top is a recharge model — API rate limits scale with cumulative top-ups from $1 (Tier0) to $3,000 (Tier5), and launch promotions grant 10–30% voucher credit on large single top-ups. The K3 rebate running to 2026-08-12 shows how sharp that mechanic has become: one reward per Organization ID, calculated only from the highest-value transaction on the day of your first top-up in the window, on non-refundable balance. It is an uncontracted prepaid commit that pushes buyers to make one big, immediate prepayment — consumer psychology doing the work an annual contract normally does.

5. The same tier priced two ways at once. As of the 2026-08-28 capture, Kimi Business runs a self-serve $600/year/seat plan with a seat stepper and Subscribe checkout on kimi.com/membership/pricing, while the dedicated kimi.com/zh-cn/business marketing page for the identical tier still reads “Contact sales” with no price shown. Most vendors resolve the self-serve-vs-sales-led choice per tier; Moonshot is running both motions simultaneously for the same seat plan, three weeks after pulling the only public price it had. Whether that is a deliberate segmentation test (self-serve for small teams, sales for larger ones) or an unreconciled migration in progress is not yet knowable from the outside — but it is a live example of how quickly a single pricing decision (publish vs. gate) can flip and coexist with its own opposite.


Strengths & weaknesses

StrengthsWeaknesses
Among the lowest public per-million-token rates — Kimi K2.6 and K2.7 Code at $0.95 in / $4.00 out undercut most Western frontier models, and K3’s arrival left every K2 rate untouchedOutput-token premium dominates: output runs 4.2× the cache-miss input rate on K2.6 ($0.95 in / $4.00 out) and 5× on K3 ($3.00 in / $15.00 out), surprising generation-heavy workloads
Deep context-caching discount (80–90% off) rewards stable system prompts, and it is deepest on the priciest model (90% on K3)Real cost depends heavily on cache-hit rate, which is hard to predict before deployment — and the penalty for getting it wrong scales with the K3 sticker
Open weights under modified MIT license — a credible self-host hedge against lock-inFlagship access is now a genuine premium: K3 at $3.00/$15.00 is ~5× the K2 line, so “Kimi is cheap” no longer describes the whole card
The core self-serve surfaces stay fully public — no “contact sales” wall on either the Kimi assistant ladder or the full per-token API, including the K3 flagshipTwo price increases in four months (K2.6 +58% input, then the K3 ceiling) confirm the era of relentless cuts is over
Free Kimi assistant, a low $19 entry tier, and a flat ~20% annual discount seed and retain adoptionThe plan card at kimi.com/membership/pricing renders nothing to a logged-out visitor; the real numbers live in a help-center article most buyers never reach, and the iOS in-app prices are a third, slightly different set
Buyers can still model the two highest-volume surfaces (assistant + API) end to end without a sales callKimi Business regained a public $600/yr/seat self-serve price on 2026-08-28, but a separate marketing page for the same tier still shows “Contact sales” with no price — the two surfaces disagree with each other
Recharge tiers reward committed developers without formal commit contracts, and the 10–30% K3 launch rebate did the same until it lapsed at its stated 2026-08-12 end dateThe moonshot-v1 sunset took effect as scheduled on August 31, 2026 — and quietly took Kimi K2.5 down with it as an undisclosed second casualty — forcing migration on a ~six-week clock with still no published successor mapping

Billing UX : usage tracking and overage controls

  • Recharge-tiered rate limits — a published six-row table maps cumulative recharge to throughput: Tier0 at $1 (3 RPM, 500,000 TPM, 1,500,000 TPD), Tier1 at $10 (200 RPM, 2M TPM, unlimited TPD), Tier2 at $20, Tier3 at $100, Tier4 at $1,000 and Tier5 at $3,000 (1,000 concurrent, 10,000 RPM, 5M TPM). You must recharge at least $1 before any call, and Moonshot reserves the right to temporarily tighten limits when the cluster is saturated.
  • Cumulative-recharge starter voucher — reaching $5 of cumulative recharge automatically grants a $5 voucher. Vouchers themselves do not count toward the cumulative-recharge total that unlocks the next tier.
  • Risk-control rate-limiting (added to the docs by 2026-07-30 capture) — Moonshot’s rate-limits page now states that abnormal account activity triggers an automatic risk-control rate-limiting policy, and once triggered “the restriction cannot be lifted” — a one-way enforcement mechanic with no published appeal path.
  • K3 Launch Top-Up Rebate — expired/withdrawn, confirmed as of 2026-09-07. A tiered top-up voucher promotion (see Pricing evolution for the rates captured 2026-07-21) was advertised through a stated 2026-08-12 end date, on the pay-as-you-go API only. Since the 2026-07-30 capture, the dedicated promotion page (/docs/pricing/promotion) and the “Promotion” sidebar entry have been replaced by a generic Help Center FAQ with no rebate mention, and this remains the case as of the 2026-09-07 recapture (well past the stated 2026-08-12 end date) — the offer has not resurfaced, though Moonshot has not published a formal end announcement.
  • Automatic context caching — every current model (K3, K2.7 Code, K2.6) supports automatic context caching, and the cache-hit input rate is a separate published column billed 80–90% below cache-miss. Kimi K2.5 supported the same mechanic before its August 31, 2026 retirement.
  • Per-request reasoning control — K3 exposes a top-level reasoning_effort field (low / high / max, default max), so the cost of thinking is a request-level dial rather than a separate SKU.
  • Tax handling at checkout — the rate card states that prices exclude applicable taxes and that tax is calculated at checkout based on your jurisdiction.
  • Open-weight escape hatch — because the K2 family is published on Hugging Face, teams can self-host to cap cost rather than scaling hosted spend.
  • Consumer annual billing — each paid Kimi tier has a matching once-a-year price ($180 / $372 / $948 / $1,908, i.e. $15 / $31 / $79 / $159 per month), a flat ~20% commit-for-discount lever on the consumer side. Credits reset at the start of each billing cycle, on the subscription anniversary rather than the calendar month.
  • Currency split — an international USD card (platform.kimi.ai) sits alongside a China-native RMB ¥ card, with rates and availability that can differ by region.
  • “Join Waitlist” gating ahead of a plan split (added 2026-08-28 capture) — the Kimi assistant plan page and the Kimi Code plan page both display a “New Membership Plans Coming Soon” banner (Kimi and Kimi Code benefits will be separated; existing subscribers unaffected) and every plan tier’s purchase button now reads “Join Waitlist” instead of a direct buy CTA — even though the banner text says the current plan can still be bought before launch.
  • Self-serve seat stepper for Kimi Business (added 2026-08-28 capture) — the “Business” tab on kimi.com/membership/pricing exposes a /+ seat-quantity control (minimum 2 seats) and a “Subscribe” button that checks out at $600/year/seat with no sales contact, alongside a still-live sales-only “Contact sales” path on the separate Kimi Business marketing page.

Strategic wins : Why Moonshot AI’s pricing decisions worked

1. Turning long context into a price axis, then a brand

Moonshot built its early reputation on long context, then priced it directly — the moonshot-v1 context tiers made “how much context you need” a literal billing dimension. That tied the headline differentiator to the revenue line and trained the market to associate Kimi with long-context value before the price war began. The sunset closes the loop cleanly: once a 262,144-token window became table stakes on K2 and K3 shipped with 1,048,576, the axis had nothing left to sort buyers by, and Moonshot retired it exactly on schedule on 2026-08-31 rather than defending it or quietly extending it. See choosing the right usage metric for why aligning the meter with the differentiator compounds — and why a meter has a shelf life.

2. Pioneering context caching as a cost lever

By shipping context caching in 2024 — billing cache hits ~80–85% cheaper — Moonshot gave developers a way to slash real costs on stable, repeated context, which made aggressive headline rates even more attractive for agentic and RAG workloads. It was early enough to influence how the broader market now prices reused context, a structural win beyond any single rate. This is the usage-based pricing discipline of pricing the marginal cost, not the gross call.

3. Open weights plus a price war to win developer share

Releasing Kimi K2 open-weight and pricing hosted inference aggressively enough to top Hugging Face downloads turned model R&D into distribution — developers evangelize the open models while Moonshot monetizes managed inference and the assistant. Pairing that with recharge bonuses built a committed-spend base, mirroring the shift away from rigid licensing toward flexible, usage-anchored monetization.

4. Raising the ceiling instead of raising the card

The July 2026 K3 launch took Moonshot’s top rate from $0.95/$4.00 to $3.00/$15.00 without moving a single existing price: K2.6, K2.5 and the new K2.7 Code all stayed put. That converts what would have been a 3× price increase into a self-selection problem — teams that need a 2.8T-parameter model with a 1M-token window pay for it, and everyone else keeps the rate they budgeted for. Compared with April’s K2.6 bump, which repriced the model developers were already calling and drew “price hike” coverage, the ceiling move buys the same revenue mix expansion with none of the migration friction, and it pairs the increase with a deeper 90% cache discount so the premium is escapable by design.


Areas to improve : Gaps in Moonshot AI’s pricing approach

1. Make total cost predictable before deployment

Because the bill hinges on cache-hit rate and model choice, the headline rate understates real spend — and Kimi K3 raised the cost of guessing wrong by roughly 5×. A “estimated cost per workload” calculator that factors expected cache hits, model tier and the K3-versus-K2 decision — surfaced before the first top-up rather than after — would reduce the bill-shock and unpredictability risk that usage pricing is meant to remove, especially now that a non-refundable prepaid balance funds the meter.

2. Publish the assistant plan card to logged-out buyers

The Kimi assistant tiers (Adagio through Vivace) lead with agent-credit counts and code-credit multipliers rather than numeric message and long-context caps, and the plan page at kimi.com/membership/pricing renders nothing to a logged-out visitor — a prospective subscriber has to find the help-center article to learn that annual billing runs $180 / $372 / $948 / $1,908, or read the App Store listing and get a slightly different set of Apple price points. Publishing those numbers on the plan card itself with concrete per-tier quotas would let buyers self-select without fear of silent throttling during capacity crunches — the very problem the 2024 tipping feature exposed — and would make the consumer track as verifiable as the API card already is.

3. Publish the migration mapping the sunset never got — before the next one

The moonshot-v1 sunset landed exactly on schedule on 2026-08-31, roughly six weeks after it first appeared in the docs — and Moonshot still shipped it with no per-SKU successor mapping, just a blanket “migrate to kimi-k3 or other latest models.” That vagueness got materially worse on the sunset date itself: Kimi K2.5, the obvious low-cost landing spot for displaced moonshot-v1-8k and -128k traffic, was retired the same day without ever being named in the July announcement, so buyers who spent six weeks planning a migration onto K2.5 had that plan break on go-live day. A one-page table mapping each retired SKU to its nearest live model — published the day a deprecation is announced, and kept current if the target itself later gets deprecated — would turn a silent repricing into a decision buyers can plan around, the same discipline as picking a meter buyers can forecast, covered in understanding usage-based pricing models.

4. Reconcile the USD and RMB cards

The international USD card and China-native RMB ¥ card can diverge in rate, model availability, and cadence (the K2.6 increase was expressed partly in yuan). A clearer, reconciled cross-currency view would help global teams evaluating Moonshot against other AI companies’ transparency avoid surprises tied to which card they land on.

5. Reconcile the two contradictory Kimi Business surfaces

The enterprise tier’s price visibility has now flipped twice in a month: live at ~$599/yr/seat through 2026-07-30, pulled to sales-only on 2026-08-04, then restored as a self-serve $600/yr/seat “Business” tab on kimi.com/membership/pricing on 2026-08-28 — while the dedicated kimi.com/zh-cn/business marketing page for the same tier still shows only “Contact sales” with no price. A prospect who lands on the marketing page today still sees a sales wall for a plan they could buy directly one click away on the membership page. Pointing both surfaces at the same checkout — or at minimum cross-linking them — would end the churn in what buyers are told about this tier and stop the page from contradicting itself.

Key takeaways

  1. Price the differentiator — then retire the axis when the product absorbs it. Moonshot turned long context into a literal billing axis on moonshot-v1, then sunset that family on August 31, 2026 once million-token windows made the axis meaningless. A meter has a shelf life, and holding one past its usefulness is how price sheets calcify. The same cutover also retired Kimi K2.5 without naming it in the original July announcement — a reminder to scope a deprecation notice to everything it will actually touch, not just its headline casualty.
  2. Caching is the real meter. An 80–90% cache-hit discount means the sticker rate is only half the story, and Moonshot cut it deepest (90%) on its most expensive model — so the discount is doing the work of making a premium tier reachable rather than just rewarding good prompt hygiene.
  3. Open weights make aggressive pricing safer. Releasing Kimi K2 open-weight gave Moonshot distribution and an escape hatch that blunts backlash — even when it later raised prices on K2.6 and opened a 5× premium above it.
  4. Raise the ceiling, not the whole card. April’s +58% K2.6 bump repriced the model everyone was calling and read as a market signal; July’s Kimi K3 added a $3.00/$15.00 rung while leaving every existing rate alone, capturing high-end willingness-to-pay without forcing a single customer to migrate. August added a wrinkle to that pattern: Kimi Enterprise (Business) pulled its only public per-seat/year price on 2026-08-04 and moved to sales-only, then regained a public, self-serve $600/yr/seat price on 2026-08-28 under the Kimi Business name — but on a different page than the one that went sales-only, which still shows “Contact sales” with no price. The self-serve assistant and API card stayed untouched throughout; only the highest-touch tier’s price visibility moved, twice, in the same month.
  5. Recharge mechanics carry consumer psychology into a dev API. Tiered rate limits and a launch rebate that only counts your first day’s largest top-up reward committed prepaid spend without formal commit contracts — a consumer-style lever applied to developer monetization.

UBP implications

  1. A billable dimension has a lifecycle, and retiring one is a repricing — but publication decisions can also reverse. Moonshot showed that “how much context you need” can be tiered and charged for — and then showed the other half of the lesson: when the capability commoditizes, the axis is decommissioned, and everyone sitting on its cheapest rung (moonshot-v1-8k at $0.20/M) gets silently repriced upward. A public price can move the same way in both directions: Kimi Enterprise (Business) lost its only public per-seat/year rate on 2026-08-04, then regained one — self-serve, at $600/yr/seat — just three weeks later on 2026-08-28, on a different page than the one that had gone dark, which still shows a sales-only “Contact sales” state for the identical tier. Publishing (or pulling) a starting price is a standing operational choice, not a one-time launch decision, and when two surfaces for the same tier disagree, UBP designers should treat the reconciliation as its own deliverable, not an afterthought. The August 31 cutover sharpened the axis-retirement half of that lesson further: Kimi K2.5 — never mentioned in the original sunset notice — was retired the same day, so the SKU that would have absorbed moonshot-v1’s cheapest-tier traffic disappeared before that traffic could land on it. A deprecation notice is a commitment about scope as much as timing, and UBP teams should audit every adjacent SKU before publishing one, not just the SKU being named.
  2. Price the marginal cost, not the gross call. Context caching prices reused context near its true marginal cost, which makes aggressive headline rates sustainable. Moonshot’s July move goes further by widening the cache discount to 90% exactly where the sticker is highest — the discount is what makes a 5× premium tier sellable, so the escape hatch should be designed alongside the increase, not after it.
  3. Open weights reshape the value question from “what” to “where” — and increasingly “how fast.” When the model is free to download, the priced dimension becomes managed inference, caching, and the assistant rather than the model itself; the K2.7 Code HighSpeed SKU, identical to its base model at exactly double every rate, shows throughput emerging as an independently priced meter. UBP design has to follow the cost driver customers can’t trivially replicate, an early signal of the move toward outcome-shaped pricing.

Bottom line

Moonshot AI prices two surfaces from its Kimi platform: a tempo-named assistant ($0 Free to $199/mo Vivace, with annual billing a flat ~20% cheaper) and a per-token API that now spans a 15.8× range, from $0.95/M input on Kimi K2.6 to $15.00/M output on Kimi K3. July 2026 reshaped the card rather than just its level — Kimi K3 opened a genuinely premium ceiling at $3.00 in / $15.00 out while every K2 rate stayed put, and the context-tiered moonshot-v1 family was retired on schedule on August 31, 2026, taking context length off the price card as a billing axis — and quietly taking Kimi K2.5, an undisclosed second casualty, down with it, leaving Kimi K3, K2.7 Code and K2.6 as the only priced models. August then turned into a case study in price-visibility churn at the top of the card: Kimi Enterprise (Business) pulled its only disclosed per-seat/year price on 2026-08-04 and moved to a sales-only motion, then regained a public, self-serve $600/yr/seat price on 2026-08-28 under the Kimi Business name — on a different page than the one that went dark, which still shows “Contact sales” with no price. The self-serve assistant and API stayed fully public the entire time. What remains constant is the deep context-caching discount Moonshot pioneered in 2024, now 90% off on K3, layered over open weights you can download and self-host. The main friction is cost predictability: the real bill depends on cache-hit rate and model choice far more than the headline rate suggests, and with K3 on the card — and both the legacy floor and Kimi K2.5 now gone — the cost of choosing wrong is roughly 5× what it was.

Kimi K2.5 and moonshot-v1 officially retired; both now 404

Moonshot's API docs confirm the moonshot-v1 sunset flagged 2026-07-21 took effect on schedule and disclose an undisclosed second casualty: 'The kimi-k2.5 and moonshot-v1 series were officially retired on August 31, 2026.

Kimi K2.5 — the cheapest model in the Kimi K-series line and the holder of the platform's lowest published cache-hit rate ($0.10/M) — was never named in the original sunset notice. Both dedicated pricing sub-pages now redirect to a generic Model List doc, and neither model appears on the live Model Pricing nav (K3, K2.7 Code, K2.6, Other only).

Kimi Business regains a public self-serve price at $600/yr/seat

A new 'Business' tab discovered on kimi.com/membership/pricing — a page that rendered no prices to crawlers as recently as 2026-08-04 — shows a self-serve $600/year/seat 'Premium' card (minimum 2 seats) with a working seat stepper and Subscribe checkout, close to the $599/yr/seat rate pulled on 2026-08-04. The dedicated Kimi Business marketing page (kimi.com/zh-cn/business, now rendering English content) still shows only 'Contact sales' with no price, so a self-serve and a sales-led path now coexist for the same tier. Separately, the Kimi assistant and Kimi Code plan pages now show a 'New Membership Plans Coming Soon' banner (Kimi and Kimi Code benefits will be separated; existing subscribers unaffected) with every plan tier's purchase button reading 'Join Waitlist' instead of a direct buy CTA.

moonshot-v1 sunset on August 31 retires context-as-a-meter

Moonshot's model-pricing overview now describes the Moonshot V1 family as the 'classic generation model series; full platform sunset expected on August 31', ending the mechanic that charged different per-token rates for the same model by context window ($0.20/$2.00 at 8k up to $2.00/$5.00 at 128k). The legacy Kimi K2 0711/0905/Turbo and K2 Thinking models have also disappeared from the card. Migration is not price-neutral: moonshot-v1-128k users move down to Kimi K2.5 at $0.60/$3.00 with double the context, while moonshot-v1-8k users lose the cheapest input rate on the platform and land on a 3× higher one.

Kimi K3 launches at $3.00/$15.00 — a new price ceiling

Moonshot ships flagship Kimi K3 (2.8-trillion parameters, natively multimodal, 1,048,576-token context) on its research page dated 2026-07-16 and prices it at $3.00/M input (cache miss), $0.30/M cache-hit input and $15.00/M output — roughly 3.2× the input and 3.75× the output of Kimi K2.6. A coding SKU, Kimi K2.7 Code, sits below it at $0.19/$0.95/$4.00 per 1M with a HighSpeed variant at exactly double ($0.38/$1.90/$8.00) that buys throughput only. K2.6 and K2.5 rates are untouched, so the increase is a new rung above the ladder rather than a repricing across the card, and a launch top-up rebate (2026-07-15 to 2026-08-12) returns 10–30% of a single top-up as vouchers.

On 2025-07-11 Moonshot releases Kimi K2 open-weight — a 1-trillion-parameter Mixture-of-Experts model (32B active) — at aggressive API rates (around $0.15/M cache-hit input, $2.50/M output). It becomes the fastest-downloaded model on Hugging Face one day after launch and pressures OpenAI/Anthropic on price. (Source: HPCwire, Hugging Face; accessed 2026-06-11.)

Context caching pioneered to cut repeated-prompt cost

Moonshot rolls out context caching for its API — billing cache-hit prompt prefixes at a fraction of the cache-miss rate (roughly 80–85% off). It becomes a defining cost lever and an industry-influencing primitive other LLM vendors later adopt. (Source: aggregator/press reconstruction; accessed 2026-06-11.)

Viral 'tipping/recharge' reward to buy priority

Amid capacity crunches, Kimi introduces a paid tipping/recharge feature letting users pay to jump the queue and get priority during peak load — an early, much-discussed test of individual willingness-to-pay. API rate limits are also tiered by cumulative recharge. (Source: Baidu Baike, contemporaneous reporting; accessed 2026-06-11.)

2M-character context goes viral; per-token API live

Kimi expands lossless context from 200,000 to 2,000,000 Chinese characters, which goes viral across Chinese social media and drives a user surge. The moonshot-v1 developer API bills per million tokens with context-length-tiered rates (8k/32k/128k priced separately). (Source: Wikipedia, contemporaneous press; accessed 2026-06-11.)

Kimi assistant launches free, built around long context

Moonshot AI (founded March 2023) releases the Kimi assistant on 2023-10-09 — a free consumer chatbot positioned around long-context, the world's first product supporting 200,000-character Chinese input. Monetization is deferred; the product grows on the long-context hook. (Source: Wikipedia, Baidu Baike; accessed 2026-06-11.)

Trivia
  • · Moonshot AI's name (月之暗面, 'Dark Side of the Moon') comes from founder Yang Zhilin's favorite Pink Floyd album — the company launched on the album's 50th anniversary in March 2023.
  • · The legacy moonshot-v1 API charged different per-token rates for the SAME model depending on context window: $0.20/$2.00 per 1M at 8k, but $2.00/$5.00 at 128k — context length was literally the price axis, until the whole family was officially retired on August 31, 2026.
  • · Moonshot pioneered context caching for LLM APIs in 2024; cache-hit input is billed ~80–90% below cache-miss (e.g. $0.16/M vs $0.95/M on Kimi K2.6).

Questions & answers

What is Moonshot AI's pricing model?
Moonshot runs three tracks: subscriptions for the Kimi assistant (Free, then $19/$39/$99/$199 per month), a usage-based per-token API, and Kimi Business, a team/enterprise seat plan. Every current API model is billed per million tokens with separate cache-hit and cache-miss input rates, and API rate limits scale with cumulative recharge. Kimi Business briefly went sales-only after its only public per-seat/year price was pulled on 2026-08-04, then regained a public, self-serve price of $600/year/seat (minimum 2 seats) on 2026-08-28 via a new 'Business' tab, even as a separate marketing page still offers only a sales-led 'Contact sales' path with no price shown.
Does Moonshot AI (Kimi) offer a free tier?
Yes. The Kimi assistant has a Free plan (named Adagio) at $0/mo with 6 agent credits, one concurrent agent task and 200 professional-database calls. The original Kimi assistant launched free in 2023 and became famous for long-context (up to 2 million Chinese characters).
How much does the Kimi K3 API cost per million tokens?
Kimi K3, the flagship model, is $3.00 input (cache miss) / $15.00 output per 1M tokens, with cache-hit input at $0.30/M and a 1,048,576-token context window. It is the most expensive model on Moonshot's card by a wide margin — K2.6 and K2.7 Code are $0.95 in / $4.00 out.
Why does Moonshot charge different rates for the same model?
The legacy moonshot-v1 family was context-length-tiered: moonshot-v1-8k, -32k and -128k each carried a different per-token rate for the same model, rising with the context window. That family — along with Kimi K2.5 — was officially retired on August 31, 2026; calls to either now return a 404 (model not found) error. The Kimi K2/K3 models fold long context into one flat per-model rate instead.
What is context caching and how much does it save?
Moonshot pioneered context caching for LLM APIs in 2024. Repeated prompt prefixes that hit the cache are billed at a fraction of the cache-miss rate — 80–90% off on every current model (for example $0.16/M cache-hit vs $0.95/M cache-miss on Kimi K2.6, or $0.30/M vs $3.00/M on Kimi K3).
Are Kimi models open-weight?
Yes. Kimi K2 (a 1-trillion-parameter Mixture-of-Experts model launched July 2025) and its successors are released open-weight on Hugging Face under a modified MIT license, while Moonshot monetizes hosted inference per token and the managed Kimi assistant.
