Anthropic launches Claude Sonnet 5.5 with faster output
Sonnet 5.5 is pitched as the faster, cheaper Claude 5.5 model for bounded daily work.
Anthropic says the model runs more than 30% faster than Sonnet 5 and can cost up to 30% less per task for most workloads, while per-token pricing stays unchanged. The piece cites large benchmark gains, including 70.6% on Terminal-Bench 4.0 versus 10.3% for Sonnet 5. It is available across Claude platforms and major clouds under `claude-sonnet-5-5`, with adjustable effort settings. Anthropic is also bringing Opus-style cyber safeguards to this Sonnet release, while saying routine software development and most life sciences work should not be affected. TestingCatalog's note
