Claude Sonnet 5.5 API

US Anthropic | выпущен 2026-10

Claude Sonnet 5.5 is the workhorse of the Claude family for well-scoped daily work: drafting, refactoring, analysis and tool-driven automation. It balances frontier-adjacent quality with markedly better economics than Opus, making it the default Claude for production traffic.
