Looking Beyond Azure AI Foundry?

Foundry gives you the models Azure hosts — after you create resources, deployments, and quotas. LLM Gateway gives you every major lab and cloud — including Azure itself — behind one open-source, OpenAI-compatible API. No provisioning required.

Already on Azure? Keep it — and stop depending on it.

Azure OpenAI and Azure AI Foundry are built-in LLM Gateway providers. Bring your Azure credentials and your traffic keeps flowing with 0% markup — while every request gains automatic failover to other providers, response caching, guardrails, and per-request cost analytics. When you need a model Foundry doesn't host, it's already behind the same API.
