Anthropic has released Claude Sonnet 5, a significant upgrade over Claude Sonnet 4.6 with improvements in coding, reasoning, tool use, and agentic capabilities. The model can autonomously use tools like browsers and terminals, with adaptive thinking enabled by default. It offers performance close to Opus 4.8 at lower prices: introductory pricing of $2/million input tokens and $10/million output tokens through August 31, 2026, rising to $3/$15 afterward. It is available across all Claude plans, in Claude Code, and via the Claude API.
