Claude Opus 5 launches as Anthropic's new flagship coding model

Anthropic’s claude.com/pricing API tab now headlines Claude Opus 5 — described as “ideal for complex agentic coding and enterprise work” — alongside Claude Fable 5, Claude Sonnet 5, and Claude Haiku 4.5 as the four current-generation models shown at the top of the page. Opus 5 carries the exact per-token rate Opus 4.8 held: $5/MTok input, $6.25/MTok for 5-minute prompt-cache writes, $0.50/MTok for cache reads, and $25/MTok output. Opus 4.8 has been repositioned into the page’s “Legacy models” section next to Opus 4.7, Opus 4.6, and Opus 4.5 — all of which remain live at the same $5/$25 rate.

Claude Sonnet 5 ($2/$10 introductory through August 31, 2026; $3/$15 standard after), Claude Fable 5 ($10/$50), and Claude Haiku 4.5 ($1/$5) are unchanged from the prior capture, as are the Free/Pro ($17 annual, $20 monthly)/Max (from $100/mo) individual plans and the Team ($20-$100/seat/mo) and Enterprise ($20/seat + usage) plans. Because the new flagship carries over its predecessor’s price, this is a model-lineup change rather than a price move — Anthropic added a SKU without changing what the top Opus tier costs.
