MuiRouterLLM Router
One LLM router for every provider
Stop maintaining a separate integration for each model vendor. MuiRouter routes your large language model calls across OpenAI, Claude, Gemini, Workers AI and MiMo from a single key and a single bill.
Why route LLMs through one API
Switch models with one string
Change the model name in your request to move between GPT, Claude, Gemini and MiMo — no new SDKs, no new keys.
Unified usage and billing
Every model shares one wallet, one usage log and one API key, so cost tracking stays simple as you add models.
Native passthrough when you need it
Use OpenAI-compatible mode for portability, or pass through to a provider's native API to keep Claude's long context or Gemini's multimodal features.
Resilient routing
Spread traffic across providers and fall back to alternatives when an upstream model is unavailable.
LLM router FAQ
- What is an LLM router?
- An LLM router is a gateway that sends your prompts to different large language models through one interface. It lets you compare, switch or combine models like GPT, Claude and Gemini without rewriting your integration.
- How do I switch between models?
- Keep the same OpenAI-compatible request and change the model field — for example from a GPT model to a Claude or Gemini model. MuiRouter routes it to the right provider.
- Can I use my existing OpenAI code?
- Yes. MuiRouter is OpenAI-compatible, so you only change the Base URL and API key. See the OpenAI-compatible router page for details.
