Envoy AI Gateway

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.

Supported AI Providers

Envoy AI Gateway supports a wide range of AI providers, making it easy to integrate with your preferred LLM services:

OpenAI	Azure OpenAI	Google Gemini	Vertex AI	AWS Bedrock
Mistral	Cohere	Groq	Together AI	DeepInfra
DeepSeek	Hunyuan	SambaNova	Grok
