OpenAI GPT 5.6 on Snowflake Cortex AI

Details

Snowflake announced same-day private preview availability of OpenAI's GPT-5.6 model family on its Cortex AI platform, acting as a launch-day partner. All three GPT-5.6 variants are accessible through Snowflake Cortex AI Functions and the Cortex REST API: Sol (strongest, targeted at coding, biology, and cybersecurity), Terra (balanced, 2x cheaper than GPT-5.5 at comparable performance), and Luna (fast, affordable). The integration targets two enterprise workflows. CoCo, Snowflake's AI coding agent, uses GPT-5.6 to improve reasoning, code generation, and long-running agentic task execution within Snowsight, the CLI, and local dev tools. CoWork, a newer product, lets employees query complex organizational data in natural language — with GPT-5.6 enabling autonomous orchestration of analytical and operational workflows. Snowflake's pitch is data governance: these models run inside Snowflake's secure perimeter, allowing enterprises to use frontier models without data leaving their governed environment. Terra's 2x cost reduction versus GPT-5.5 at matched performance is the most concrete detail disclosed, though specific pricing figures are not included in this announcement.
