Sonnet 5.5 is here! In Claude Code, users get ~30% more tasks done compared to Sonnet 5. It's smarter, so it needs fewer tokens for the same work.
Here it rakes a yard of leaves using tool calls. 24s faster than Sonnet 5, with 6K fewer tokens. It leaves her extra time to read :)
Introducing Claude Sonnet 5.5, the second model in the Claude 5.5 family.
It’s a clear upgrade over Sonnet 5, runs more than 30% faster, and costs up to 30% less for most work.
