  1. for example, we can add the following request headers for tracking
    a. x-ai-trace-id
    b. x-ai-user-id
    c. x-ai-metadata
    d. ...

this is a request example:

 curl https://api.xxxxai.com/v1/completions \
  -H "Content-Type: application/json" \
  -H "Authorization: Bearer $API_KEY" \
  -H "X-AI-TRACE-ID: $TRACE_ID" \
  -H "X-AI-USER-ID: $USER_ID" \
  -H "X-AI-METADATA: $METADATA" \
  -d '{
    "model": "gpt-3.5-turbo-instruct",
    "prompt": "Say this is a test",
    "max_tokens": 7,
    "temperature": 0
  }'

2.For example, on the openai official website, you can choose the model when chatting. the model parameter is not fixed on the llm node.

It can be done like this, however, to change the models in api level is not the way we want.

yes, but why not design it to be more flexible? can you tell me the reason for this design? Is it possible to support adding headers to llm node? @crazywoola
