Anthropic Launches Claude Sonnet 5 With Near-Opus Performance at a Lower Price

Anthropic today introduced Claude Sonnet 5, a more affordable model that narrows the gap between Sonnet and Opus. Anthropic says Claude Sonnet 5 is its most agentic Sonnet model to date, able to make plans, use tools like browsers and terminals, and run autonomously. Opus models have better agentic capabilities, but they're more expensive than Sonnet models.
