Anthropic says Sonnet 5.5 generates responses more than 30% faster than Claude Sonnet 5 and can reduce per-task costs by up to 30%, according to Moneycontrol. Moneycontrol reports that Anthropic attributes those task-cost savings to lower token usage.

Where Anthropic says it improved

Anthropic is pitching Sonnet 5.5 for relatively well-defined work, especially software tasks. According to Moneycontrol’s report, Anthropic says the model is built to handle multi-step coding tasks, understand codebases and reduce the number of steps needed to complete work.

Anthropic also points to benchmark gains. According to Moneycontrol’s write-up, Sonnet 5.5 scored 70.6% on Terminal-Bench 4.0, compared with 10.3% for Sonnet 5.

Where you can get it

Claude Sonnet 5.5 is available through Anthropic and major cloud providers including Amazon Web Services, Google Cloud and Microsoft Azure, according to Moneycontrol.

That makes the launch less about a lower list price than about Anthropic’s broader pitch for the middle of its lineup: a model the company says can handle a lot of routine coding and knowledge-work jobs faster, and at lower total task cost, than the previous Sonnet release.
