What should frontier intelligence cost?
Less. So more people can put it to work.
We're Circuit & Chisel. We build Pareto, an AI model that blends frontier and open models to make capable AI more affordable. Use it through Unbiased, our platform for chat, coding and the API.
Pareto 26.10 Preview: see the results →Cost determines what gets built.
When AI is expensive, people have to limit where they use it. Lower the cost, and more ideas become worth trying.
Our mission is to increase access to AI for everyone by reducing the cost of frontier AI.
No hype. No noise.
02 / Our work · Pareto 26.10 Preview
Capability and cost. Side by side.
Pareto blends frontier and open models. We evaluate it on coding, terminal use and reasoning, reporting the score alongside the cost per task.
In preliminary results, Pareto 26.10 Preview is matching or setting the Pareto frontier on all four benchmarks.
$0.24 per task. Terminal-Bench 4.0 50.8 Agentic terminal use.
$0.48 per task. HLE (text-only) 49.9 Expert reasoning.
$0.008 per task. GPQA-Diamond 92.4 Science reasoning.
$0.004 per task.
Preliminary runs from October 1, 2026; results may change before final publication. Scores out of 100; costs are reported mean USD per task, not token prices. Denominators and cost methodology require confirmation.
Published competitor results use different evaluators, harnesses and settings, not a controlled head-to-head. See the results and methodology →

The people behind the work.
Our founders came from Stripe. We first built ATXP, payment rails that let AI agents discover services and pay for the tools they need. Today, we're focused on cutting the cost of frontier intelligence through Pareto and Unbiased.
