Hey team! 👋 I’m trying to connect my Azure OpenAI deployment to VAPI and I’m running into some issues with the integration. ✅ What I’ve tried: 1. Model: gpt-4o-mini - Deployment name:

gpt-4o-mini

- Region:

eastus2

- API version:

2025-01-01-preview

- Status: Fails connection test in VAPI, but works perfectly via Python. 2. Model: gpt-4.1 - Deployment name:

gpt-4.1

- Region:

eastus2

- API version:

2025-01-01-preview

- Endpoint:

https://samue-mbut5u57-eastus2.cognitiveservices.azure.com/openai/deployments/gpt-4.1/chat/completions?api-version=2025-01-01-preview

- Status: Also fails the VAPI test, but works fine using the Python SDK. 🔐 I’m using the correct API key, region, and endpoint. The

OCP-APIM-Subscription-Key

is left blank (as recommended for Azure OpenAI). Everything works fine outside of VAPI. ❓ Are these models (especially gpt-4o-mini or gpt-4.1) supported yet in VAPI AI? Or could the issue be related to the newer

2025-01-01-preview

API version? Would appreciate any guidance — thanks a lot in advance! 🙏

i have the same issue

Make sure the deployment name in Azure matches exactly, and that the same model is available on both the VAPI and Azure. This will ensure it works properly.
