⚡ AI Gateway

**A protocol-faithful, multi-provider AI gateway written in Rust.**

Route requests across OpenAI, Anthropic, Google Gemini, and the entire OpenAI-compatible ecosystem — with native wire types, streaming SSE, and zero lowest-common-denominator abstractions.

Why AI Gateway?

Most multi-provider LLM wrappers force every provider into a single "universal" message format, silently dropping fields and features along the way. AI Gateway takes the opposite approach:

Protocol-faithful — Each provider crate models the upstream API exactly as documented. No fields are silently dropped, no semantics are lost.
Forward-compatible — All wire types carry #[serde(flatten)] extra to survive upstream API changes without recompilation.
Translation at the edge — Cross-provider mapping happens at the gateway layer via TryFrom/Into, not inside individual providers.
Streaming-first — Full SSE event fidelity for every provider.
