Glean cuts Model Hub rates for GPT 5.6 Terra and Luna up to 80%
Glean's Model Hub Usage rate card cut GPT 5.6 Terra 20% and GPT 5.6 Luna 80% per million tokens, and reclassified Luna from Premium to Standard in the Enterprise Flex FlexCredit tier table.
GPT 5.6 Terra $2.50 in / $15.00 out per million tokens; GPT 5.6 Luna $1.00 in / $6.00 out, listed as a Premium model that always consumes FlexCredits on Enterprise Flex.
GPT 5.6 Terra $2.00 in / $12.00 out (-20%); GPT 5.6 Luna $0.20 in / $1.20 out (-80%); Luna moved to the Standard tier, so it now falls inside the included 100/user/week Thinking and Adaptive Reasoning allowance instead of always billing FlexCredits.

Glean’s two commercial rate cards moved together this week. On the dollar-denominated side, the Model Hub Usage table at docs.glean.com/glean-core-suite-pricing (last updated 2026-07-30) cut GPT 5.6 Terra’s per-million-token rate 20% (input $2.50→$2.00, cache write $3.125→$2.50, cache read $0.25→$0.20, output $15.00→$12.00) and GPT 5.6 Luna’s 80% (input $1.00→$0.20, cache write $1.25→$0.25, cache read $0.10→$0.02, output $6.00→$1.20) — the first published price decreases tracked on this card since Glean began disclosing dollar rates in July 2026.
The credit-denominated side moved in the same direction: Glean’s Enterprise Flex model-tier docs (footer now dated 2026-08-04) reclassified GPT 5.6 Luna from Premium to Standard, so it now falls inside the seat-included 100-query/user/week Thinking and Adaptive Reasoning allowance instead of always consuming FlexCredits at the current rate card. GPT 5.6 Sol and Terra remain Premium. Separately, Glean’s usage-limits docs (last updated 2026-07-31) added a fourth spend-control tier — a per-department monthly cap, not pooled, enforced between individual per-user overrides and the org-wide default.
Glean still discloses no seat price on either Enterprise Flex or Glean Core Suite; both changes landed inside the docs, not on glean.com/pricing, which continues to 301-redirect to the homepage.
Glean's usage-limits docs add a fourth cap tier: admins can now set a monthly usage limit per department (not pooled — the same cap applies to every member), enforced between an individual per-user override and the org-wide default user limit. Requires department metadata from the identity provider or org chart; Glean's own guidance recommends alert-only limits before enabling hard caps.
