Anthropic releases Sonnet 5.5, a faster mid-range AI model
Anthropic unveiled Claude Sonnet 5.5, the second model in the Claude 5.5 family, highlighting a roughly 30% speed boost and reduced token costs versus Sonnet 5. It is positioned as a faster, lower-cost mid-range model to complement Opus 5.5, with deployment across cloud platforms and zero-data-retention support. The release signals ongoing product expansion ahead of an anticipated IPO.
