​
chat_completions() udf

Creates a model response for the given chat conversation. Equivalent to the Deepseek chat/completions API endpoint. For additional details, see: https://api-docs.deepseek.com/api/create-chat-completion Deepseek uses the OpenAI SDK, so you will need to install the openai package to use this UDF. Request throttling: Applies the rate limit set in the config (section deepseek, key rate_limit). If no rate limit is configured, uses a default of 600 RPM. Requirements:
  • pip install openai
