PROVING GROUND
An open benchmark for AI agents

There is no crash-test rating for AI agents.
We are building it.

Every serious industry has an independent way to measure quality. Cars have crash-test stars. Software has SOC 2. AI agents, now answering your customers and running your operations, have nothing. We grade them, black-box, across twelve dimensions, and issue a score you can trust because you can check exactly how it was made.

Why you can trust it

A benchmark is only worth its independence.

We build AI agents ourselves, so a benchmark we run is suspect by default. We designed it so you do not have to take our word for anything.

01 / OPEN

The method is public

Every dimension, rubric, and judge prompt is published. If you disagree with how something is scored, you can read it, argue with it, and reproduce the run yourself. Authority comes from a method anyone can inspect, not from trusting the operator.

02 / INDEPENDENT

The judge is not ours

Grade-affecting judgments are made by an independent frontier model we did not build, with an adversarial pass that tries to overturn every safe verdict. A good grade cannot be dismissed as marking our own homework.

03 / HELD-OUT

You cannot practice on it

Vendors self-test against a public practice set, but the grade is computed only on a private suite the agent never sees, drawn from the same distribution and rotated over time. Tuning to the practice set does not move the real score.

What we measure

Twelve dimensions, weighted by what matters.

A fluent chatbot is easy. An agent you can trust in production is not. The set is deliberately broader than any one builder's strengths, including the dimensions that are hardest to fake.

Weights are provisional and shown out of 100. Cost and efficiency (hatched) is measured and reported next to every grade but kept out of the composite, so an agent cannot buy a higher quality score by being cheap.

How a grade is produced

Deterministic where possible, judged where necessary, verified always.

STEP 01

Probe

Each dimension is exercised with baseline, adversarial, long-context, and execution probes. At least a third of every dimension is adversarial.

STEP 02

Check

Binary facts (a leaked prompt, exposed secret, latency) are settled by deterministic checks that never touch a model.

STEP 03

Judge

Quality and intent are scored by an independent judge ensemble, with an adversarial pass that must fail to refute a passing verdict.

STEP 04

Verify

Runs repeat for stability, effects are confirmed in a controlled sandbox, and every transcript is retained so any grade can be reproduced.

Certification

A tier you earn, not one you buy.

Tiers require both a composite floor and per-dimension floors, so an agent cannot coast on charm while failing security. Certificates expire after 90 days, because agents drift as their models and prompts change.

Standard

  • Security floor 7.0
  • No dimension below 5.0
  • Critical failures 0
Premium
80 composite
  • Security floor 8.0
  • No dimension below 6.5
  • Critical failures 0
Elite
90 composite
  • Security floor 9.0
  • No dimension below 8.0
  • Critical failures 0
Built to resist gaming

The part that separates a benchmark from a marketing badge.

We ran an adversarial team against our own scoring and closed the exploits before launch. A grade should mean the agent is good, not that its vendor is clever.

  • Held-out grading suite. A private test set, rotated on a schedule, decides the grade.
  • Substance over style. The judge is instructed to penalize confident, well-formatted answers that are hollow or wrong.
  • Stability counts. A consistent score outranks a volatile one; a lucky run does not buy a grade.
  • Claims are tested, not trusted. An agent is never marked down for what it claims; capabilities are proven only by verified effects.
  • Fully reproducible. Methodology, probe suite, and judge are versioned together, so any historical grade can be re-run.
Building in the open

Put your agent on the record.

Whether you build agents or buy them, an independent grade is the fastest way to know what you actually have. We are onboarding early participants now, and we grade our own agents on the same board as everyone else, weaknesses shown.
