Create OpenAI-Compatible API Using GitHub Models for Free AI Access

🚀 Want to run GitHub’s AI models seamlessly through an OpenAI-compatible API—built entirely in n8n?

This workflow creates a custom API that connects GitHub’s Models API to your n8n LLM node, letting you use GitHub AI models as if they were OpenAI models.

What it does:

🔗 Configures an OpenAI subnode with a custom credential pointing to n8n webhooks
🛠️ Creates two webhooks:
 • Models — fetches and remaps GitHub’s list of models for compatibility
 • Chat Completion — handles chat requests using GitHub’s chat endpoint with response remapping
✅ Enables smooth integration of GitHub’s AI models within your existing OpenAI workflows
✅ Setup guide & automation included

Perfect for developers wanting GitHub AI features without changing their OpenAI-based tooling.

Need help setting it up? We offer full configuration and testing for a one-time fee.
