Anthropic launches Claude Sonnet 5, its most agentic Sonnet yet

Claude Sonnet 5 features a native 1M-token context window, promotional pricing of $2/$10 per Mtok until August 31, and is available on Amazon Bedrock, Perplexity, and Databricks. It is now the default model in Claude Code and ranks second only to Fable 5 on the AA-Briefcase agentic benchmark.
