Why

Why One AI Model Isn't Enough

Think of AI models like a classroom full of students all taking the same test. No single student aces every question, but each one gets certain questions right that others get wrong.

If you could look at the answer sheet, pick the best answer from each student for each question, and combine them, you'd get a score higher than any individual student could achieve on their own. That's the idea behind LLM routing.

What

What Is LLM Routing?

Instead of sending every request to the most expensive model and hoping for the best, a router analyzes each query and sends it to the model best suited to handle it. Simple questions go to fast, cheap models. Complex tasks go to powerful ones.

The result is better performance at a fraction of the cost, because you're only paying for the capability you actually need.

How

How Sansa Does It

Sansa continuously benchmarks every model across dozens of capability dimensions, so we know exactly what each model is good at and where it falls short. When a request hits our API, a trained model built on billions of real-world examples analyzes what it needs and matches it to the best-fit model in real time.

That means your users never get a weak model on a hard task. They get the right model every time. One integration, one bill, and you never think about model selection again. Our customers save 50% on AI costs while seeing an increase in output quality, because every query gets the right model instead of a one-size-fits-all default.
