Core Idea

AISIX is a Rust-native AI gateway that puts a single OpenAI-compatible API in front of every LLM provider — OpenAI, Anthropic, Google Gemini, AWS Bedrock, Azure OpenAI, DeepSeek, and any OpenAI-compatible endpoint. Built by the original creators of Apache APISIX, shipped as a single static binary with low per-request overhead.

Key Features

• Single API: One OpenAI-compatible API for all LLM providers
• Routing & Failover: Smart model routing with automatic failover
• Governance: Rate limits, budgets, API key management
• Security: Guardrails, prompt validation
• Caching: Response caching for cost savings
• Observability: Traffic monitoring and analytics
• Self-hosted: Free, runs as a single static binary

Why This Matters

AISIX brings APISIX’s battle-tested API gateway expertise to the AI space. Being Rust-native gives it performance advantages over Python-based alternatives. It competes directly with LiteLLM, Portkey, and other AI gateways but with a focus on infrastructure-grade reliability from the team behind Apache APISIX (widely used in production API management).
