Fable 5.2 API pricing: $40 output, 20% cheaper than Fable 5.1 (Nov 10, 2026)

What changed

Anthropic's pricing page changed overnight. The featured API model card that read "Fable 5.1" on Nov 9 reads "Fable 5.2" on Nov 10, with the same description: "Next generation intelligence for long-running agents."

Change 1: Lower prices on the new model

Fable 5.1's card listed prompt caching at $0.25 per million tokens (MTok) to read and $12.50 to write, and output at $50 / MTok. Fable 5.2's card lists caching at $0.20 to read and $10 to write, and output at $40 / MTok. Each of those is 20% lower. Our snapshot of the Fable 5.2 card did not capture an input-token figure, so we are not reporting one; Fable 5.1's input rate was $10 / MTok.

Change 2: Fable 5.1 moves to the older-models list

Fable 5.1 now appears further down the page, alongside Haiku 4.5, still at its old rates: $0.25 cache read, $12.50 cache write, $10 input and $50 output per MTok.

Change 3: Fast mode covers Fable 5.2

The fast mode line changed from "Get up to 2.5x faster speeds with fast mode for Opus 5.5 at 2x standard pricing" to "...for Opus 5.5 and Fable 5.2 at 2x standard pricing."

What you can do: API customers still on Fable 5.1 pay the higher rates until they switch model versions.

What stays the same: The consumer plan cards still say Fable is included on Max and Ultra "up to half your weekly limit" and is "paid with usage credits" on Pro.

Who it affects

Developers and companies paying for Anthropic's top Fable model through the Claude API, especially long-running agent workloads that produce a lot of output or reuse cached prompts
