Anthropic releases Opus 5.5 with lower prices and Fable-level performance

Anthropic launched Opus 5.5 on Tuesday, calling it “the strongest-performing model we've tested to date.” The company claims new state-of-the-art results in coding and knowledge work, with lower prices than previous Opus models. The post doesn't disclose specific pricing, benchmark scores, or a direct comparison with Fable, so I'd hold off on the “strongest” claim until third-party evals land.

Why it matters: Anthropic's flagship model update with a price cut and Fable-level performance claim is a real signal. But the post doesn't disclose actual pricing or benchmark numbers — the two most critical pieces — so the score stays below 85.
