Ship the AI agent that works,at the lowest cost.
We test your agent on your real tasks across models and harnesses, grade what actually changed, and tell you the cheapest setup that reliably does the job.
We find the cheapest model and harness that reliably does your job.
An agent is a model inside a harness. The same model can pass twice as many tasks in a different harness, so we test the combination, on your work.
Rebuild your work as tasks
Your real workflow becomes private tasks with hidden checks, in a sandbox with mock systems.
Run every setup
Your current agent, the vendors you are weighing, our harnesses and cheaper models, on the same tasks.
Rank on what matters
Pass rate, cost per task and time per task, graded on what changed, not on what the agent said.
We don’t sell a model or an agent. Our harnesses are tested like everyone else’s.
Each failure gets a cause and a fix, and the fix is re-run to prove it.
Anonymised examples or private runs. Nothing is published without your consent.
Two-week bake-off
Give us one workflow and 20 examples. In two weeks you get every setup ranked on accuracy, cost and speed, each failure with its fix, and what switching saves you.

Run any harness with any model on real agent tasks, read every step, and see each domain's leaderboard ranked on pass rate, cost and time.
Banking & Finance→E-commerce→Government services→Multimodal & Vision→Signoff Voice
Voice agents tested on simulated phone calls in English, Hindi and Telugu, with faults injected mid-call and the grade read from the bookings made.
Open Signoff Voice →A cheaper model in the right harness does the same job.
Same tasks, same hidden checks. Only the harness or the engine around the model changed.
Gemma 4 in our harness passes 81%, above Gemini 3.8 Flash at 79% on one look. Harness scores count one-look passes plus failures re-run in the harness.
Three engine faults found and fixed: parallel tool calls, quotes in arguments, and error pages or timeouts. Graded on the bookings, not the transcript.
