We are thrilled to announce the availability of Claude Sonnet 5, Anthropic’s latest model, on Snowflake Cortex AI. As a launch partner with Anthropic, we're providing same-day availability of Claude Sonnet 5 in private preview. It is available within the secure Snowflake perimeter for use with Snowflake CoCo, Cortex Agents, Cortex AI Functions, Cortex Inference and Snowflake CoWork.

Claude Sonnet 5

Claude Sonnet 5 is a fast model with strong general capability. In testing, it performs well on coding, debugging, deep analysis and brainstorming. And, on many agentic tasks, it approaches Opus-level quality, especially at higher effort levels. It is more agentic than Sonnet 4.6; it calls more tools and runs self-verification loops to complete tasks. The model makes better use of persisted memory which improves long-horizon execution in environments like Snowflake CoCo.
