anthropic/claude-sonnet-5.5
Anthropic's newest Sonnet and the successor to Sonnet 5, at the same official price. It is the fastest Sonnet yet — over 30% faster than Sonnet 5 — and finishes tasks with fewer tokens and tool calls, so each task costs less. On coding and agentic benchmarks it lands close to Opus 5.5. Strongest at well-scoped everyday work: fixing bugs, focused features, and polished documents. 1M-token context window with native prompt caching.
