Announcing Claude Sonnet 5 on Snowflake Cortex AI

Details

Claude Sonnet 5 is Anthropic's latest model, and Snowflake is its same-day launch partner, making Snowflake Cortex AI the first enterprise data platform to offer access. The model is currently in private preview within the Snowflake environment. According to Snowflake's announcement, Sonnet 5 is positioned as a fast general-purpose model with meaningfully upgraded agentic capabilities compared to Sonnet 4.6. Key differences cited: it calls more tools per task, runs self-verification loops to complete complex work, and makes better use of persistent memory for long-horizon execution. On many agentic tasks, it 'approaches Opus-level quality, especially at higher effort levels.' The integration is available across Snowflake's product suite: CoCo (AI coding agent), CoWork (personal work agent), Cortex Agents, Cortex Inference, and Cortex AI Functions. For CoCo specifically, Sonnet 5 reportedly collapses 'weeks of glue work into minutes' for data pipelines and analytics by combining deeper reasoning with Snowflake-aware assistance. This announcement simultaneously reveals that Claude Sonnet 5 exists and is available to enterprise customers through Snowflake's platform, though general Anthropic API availability is not addressed in this source. For enterprises already in the Snowflake ecosystem, Sonnet 5 is available now within their existing security and governance perimeter.
