In the preview:

  • The underlying language model can handle several languages, however these functions are tuned for English.
  • There is rate limiting for the underlying Foundation Model APIs. See Foundation Model APIs limits to update these limits.

The ai_classify() function allows you to invoke a state-of-the-art generative AI model to classify input text according to labels you provide using SQL. This function uses a chat model serving endpoint made available by Databricks Foundation Model APIs.
