Frontier-grade accuracy. A fraction of the cost. Proof you can verify. 

Today teams pay frontier prices because they think top accuracy only comes from the biggest models — and even then, they can't prove the agent did the right thing. ByteVerity breaks that trade-off.

We wrap cheap, open models in a proof engine that checks every decision before it ships. The result isn't a smaller, worse agent — it's a better one, for a fraction of the spend, that hands you a receipt anyone can re-verify offline.

The numbers, published with their receipts:
• τ²-bench airline: 88.5% pass¹ — past the frontier leader (GLM-5.2, 87.5%) at ~9× lower cost per task.
• τ²-bench banking: 65.6% vs GPT-5.5's 37.4% — at ~43× lower cost.
• ContractNLI: 85.08% class accuracy, macro-F1 0.803.

Same accuracy tier as the frontier. One-ninth to one-fortieth the cost. And every score comes with a signed artifact you can check with our engines turned off — because "trust me" isn't proof.

How it works, one substrate, four products:
• Validity proves the risky decision core (authz, refunds, policy) is correct before it ships.
• Synthesa proves the test grading your agent is itself complete — so a green check can't hide a wrong answer.
• Control blocks PII and injection inline and signs every action at runtime.
• Lineage is the flight recorder: when something still breaks, bisect to the exact cause and prove the fix.

Frontier results without frontier bills — provable to an auditor, an underwriter, or a skeptic who trusts no one.
