Pareto 26.9, meet world!
One solution, powered by multiple models.
Unbiased is our platform. Pareto is our own blended AI model, available through the API. One model string, one bill. Under the hood it runs several models on your request and keeps the best answer. Bring-your-own-key traffic splitting is on the roadmap, not sold today.
One model, several engines
Pareto runs a mix of and open source models against each other on every request, continuously checking which one actually earns the answer, then keeps the best result for less.
One call, one response
Unbiased makes one API call per request, gives you one response. Without the manual integration changes you would usually have to manage yourself.
Not a router
Unlike , Pareto never switches models mid-conversation, so your prompt cache, and the savings, stay intact.

How does Pareto measure up to other models? →Why this exists
Nobody's job is to keep you on the most effective model.
A new frontier model ships every few weeks: ahead on one , behind on another, priced differently again. Most teams pick one model and stop checking, because checking is a full-time job nobody was hired to do. And every vendor you’d ask to check for you has a reason to recommend themselves.
Unbiased exists to do that checking for you, continuously, and to say so plainly when the honest answer is a model that isn’t ours.

We believe AI should be accessible to everyone.
Our mission is to make AI accessible to everyone, not just those who can afford frontier prices. Unbiased and Pareto are built and maintained by Circuit & Chisel, a remote-first team located across the US and Canada. And at the end of the day, we are people making tools for other people, so feel free to reach out and talk to us.
