New models added:Claude Fable 5.1 and Claude Mythos 5.1.
New model pricing added for those models:
Base input: $10 / MTok
5m cache writes: $12.50 / MTok
1h cache writes: $20 / MTok
Output: $50 / MTok
Cache hits & refreshes: $0.25 / MTok
New cache pricing rule for specific models:Claude Fable 5.1 and Claude Mythos 5.1 use a 0.025x cache hit/refresh multiplier instead of the standard 0.1x multiplier.
Prompt caching section updated accordingly: it now explicitly states that cache reads are 0.025x for Claude Fable 5.1 and Claude Mythos 5.1, and that this equals $0.25 per million tokens.
