Claude Sonnet 5 Timeline - Announcements & Release History | AI Stats
Claude Sonnet 5 data is prepared from pre-release signals and API migration materials. Availability, pricing, context length, provider mappings, and model metadata may change when Anthropic and downstream providers publish official release documentation.
Claude Sonnet 5 is Anthropic's expected next Sonnet-class model. Public Anthropic documentation is not yet available, so this record is prepared for catalog and provider support without marking the model as released.
