Claude Sonnet 5.5

Anthropic's fastest Sonnet, in Rork

Claude Sonnet 5.5 is the newest Sonnet model from Anthropic. It has a sharp eye for UI design. It generates output over 30% faster than Sonnet 5. It reads a 1M-token context, so it holds a large app in view at once.

How to use it

  1. Open the model menu in the composer, on the home page or inside a project.
  2. Pick Sonnet 5.5. It comes in five effort levels: Low, Medium, High, Extra High, and Max.
  3. Describe your app or the change you want, and send.

Sonnet 5.5 takes the place of Sonnet 5 in the menu. If you picked Sonnet 5 before, Rork now builds with Sonnet 5.5.
