+<WarningBox>
+  We recommend using `claude-3-5-sonnet` (or any newer Claude models available)
+  on Snowflake Cortex with the Cube AI API. Other models may work but are not fully tested or supported.
+</WarningBox>
+
+<InfoBox>
+The Snowflake Cortex LLM REST API uses key pair authentication. 
+Please follow the steps in [Snowflake's documentation](https://docs.snowflake.com/en/user-guide/key-pair-auth#configuring-key-pair-authentication) to generate
+a key and assign it to a Snowflake user.
+
+We recommend creating a separate Snowflake user with limited permissions for
+use with the Cube AI API.
