Coin Bureau reports that, at the default setting, Opus 5.5 is 40% cheaper than Opus 5 and 60% cheaper than Fable 5.1.
TLDR
Coin Bureau reports that Claude Opus 5.5 launched with pricing of $4 per million input tokens and $20 per million output tokens. It also relays Anthropic’s claim that the model matches Fable 5.1 on most tasks and leads Anthropic’s lineup on coding and knowledge-work benchmarks.
In a two-hour SEO test, a user says Opus reviewed 347 ranking pages across 40 keywords and found 131 content angles those pages did not cover, at a cost of $6.35. The same user says Fable handled 16 of the same keywords in the same time for $5.53—an account of one test, rather than a general performance comparison.
