Snowflake previews serverless customization of open-weight models

Snowflake introduced Cortex Training in public preview on November 3. It says teams can customize open-weight models with their own data inside Snowflake while Snowflake manages GPU infrastructure. The claimed cost advantage comes from Snowflake benchmarks and is not a guaranteed customer saving. The announcement does not describe a new foundation model made by Snowflake.
