Performance

Better than frontier models

Sansa outperforms individual frontier models by evaluating the capability profile required for each request and matching it to the best model for the task. Resulting in higher quality answers across benchmarks and real-world tasks.

Cost

Half the cost of frontier models

Not every prompt needs the most expensive model. Many inexpensive models excel in areas you would not expect, by selecting these models under the right conditions you can reduce your spend by 50% or more.

Privacy

Your data stays yours
