### Answer The error "pipeline-error-openai-llm-failed" indicates an issue with the OpenAI integration within the Vapi call pipeline. This seems to be a known issue experienced by other users as well, and it may be related to either the OpenAI service or Vapi's integration with it [(1)]() . Here are some steps you can take: 1. **Test OpenAI Directly**: Try hitting the OpenAI endpoint directly to ensure that it is working as expected. 2. **Verify Provider Keys**: Make sure your OpenAI provider keys are correctly set in the Vapi dashboard. 3. **Review Call Details**: Check the call logs for more specific error messages or details that might help diagnose the issue. If the issue persists, keep an eye on updates or fixes from the Vapi team, as it might be an integration bug that they are working on fixing.
