You can now use Claude Sonnet 5, a new model that is much better at planning tasks and using tools by itself.

Claude Sonnet 5 is designed to be more like an assistant that can think ahead and use different apps or features on its own. This means it can handle more complex requests, like browsing the web or using a terminal, without needing as much guidance from you.

It performs almost as well as the more powerful Opus 4.8 model but costs less.

Claude Sonnet 5 is built to be the most agentic Sonnet model yet.
