Claude Sonnet 5

by Anthropic

Released 21 days after Claude Fable 5 · All Anthropic releases

Claude Sonnet 5 arrived on June 30, 2026 as the strongest agent-focused Sonnet Anthropic has shipped, closing much of the gap to the Opus tier while remaining the balanced choice for everyday work. The release brought large gains over Sonnet 4.6 across coding and agent evaluations, with its biggest single jump coming on terminal-based agent benchmarks, and it extends the context window to 1 million tokens. Sonnet 5 excels at agentic coding, terminal-driven workflows, and tool-heavy pipelines where reliability per request matters as much as peak intelligence. Vision, PDF input, structured output, and native tool use make it a strong default for production assistants and multi-step automations that run at volume.
