What is an Ai model router?
An Ai model router is the layer between your prompt and the LLM. It looks at what you asked — a one-line reply, a code refactor, a research task — and sends it to the cheapest model that can answer it well. Most people overpay because they send every prompt to GPT-5. A router fixes that automatically.

Routing is the single biggest lever on Ai cost — most prompts don't need a frontier model, but most people send them anyway. LemonSugar Ai is an Ai model router with a finished chat UI on top: you ask, we route, you save.
