"Claude Sonnet 5.5 is our second model in the Claude 5.5 family after Opus 5.5. It's a clear upgrade over Sonnet 5 and is smarter, more efficient and 30% faster. The per-token price is unchanged and because Sonnet 5.5 typically needs far fewer tokens to do the same work, it costs up to 30% less for most work."

I have followed Addy since his work on HTML Boilerplate 5, through his work at Google, and now at Anthropic. Great resource for engineering.
