Claude Sonnet 5
Anthropic · USA · 2026
Anthropic's most agentic Sonnet — 1M-token context as standard, default on free and Pro plans.
Released June 30, 2026, Claude Sonnet 5 is Anthropic's workhorse frontier model: 63.2% on SWE-Bench Pro, a native one-million-token context window and strong tool-use reliability at Sonnet pricing. It became the default model for Claude's free and Pro users, bringing frontier-grade agentic coding to the mainstream.
