Good to know

  • Older Langflow versions have no OpenAI Compatible provider; use the vLLM component (api_base, api_key, model_name) instead.
Tips
  • Any model id from Models works; suffixes like :online (web search) and :nitro work too.
  • Give each tool its own key with a spend limit, so usage shows separately in Activity.
  • Something off? Error codes · Support
