Anthropic launches Claude Sonnet 5.5

Anthropic today announced it's releasing Claude Sonnet 5.5, a faster and more efficient update to its mid-tier, workhorse AI model.

Anthropic says Sonnet 5.5 generates output more than 30% faster than Claude Sonnet 5 and can reduce the total cost of completing a task by as much as 30%, primarily because it uses fewer tokens and fewer tool calls rather than because of a lower API sticker price.
