Envoy AI Gateway
December 18, 2025 ยท View on GitHub
Envoy AI Gateway is an open source project for using Envoy Gateway to handle request traffic from application clients to Generative AI services.
Usage
When using Envoy AI Gateway, we refer to a two-tier gateway pattern. The Tier One Gateway functions as a centralized entry point, and the Tier Two Gateway handles ingress traffic to a self-hosted model serving cluster.
- The Tier One Gateway handles authentication, top-level routing, and global rate limiting
- The Tier Two Gateway provides fine-grained control over self-hosted model access, with endpoint picker support for LLM inference optimization.
