This extension provides a language model provider for GitHub Copilot Chat that connects to ZenMux. ZenMux is a model gateway that unifies inference APIs from different backends (for example OpenAI, Anthropic, Vertex AI) under a single, compatible API surface. For more information, visit the official ZenMux website: https://zenmux.ai
Key points
ZenMux is a model gateway used to route and manage requests to multiple backend inference providers.
