Anthropic has released Claude Sonnet 5.5, the second model in its Claude 5.5 family. The company says the model is more than 30% faster than Sonnet 5 and costs up to 30% less for most work. Anthropic also published benchmark results for coding and other tasks; these performance figures are company-reported claims rather than independent measurements by Margalla News.
