Anthropic released Claude Sonnet 5.5, the second model in the Claude 5.5 family. It runs over 30% faster than Sonnet 5 and costs up to 30% less per task.
Token pricing stays at $2 and $10 per million input and output tokens, but the model needs far fewer tokens for the same work. It scores 70.6% on Terminal-Bench 4.0 versus 10.3% for Sonnet 5 and sits two points below Opus 5.5 on GDPval-AA.
It is the first Sonnet to ship with cyber safeguards like Anthropic's top models. Haiku 5.5 joins the family in the coming weeks.
