Claude Sonnet 5 boosts coding, reasoning, and tool use

Anthropic has released Claude Sonnet 5, an update that is substantially improved over predecessor Claude Sonnet 4.6 in coding, reasoning, tool use, and knowledge work, according to the company. Claude Sonnet 5 was introduced June 30 . It can make plans, use tools like browsers and terminals, and run autonomously at a level that required larger and more expensive models a few months ago, Anthropic said.
