Frontier AI data & evaluation

Turning
ambiguity into
intelligence.

We build the benchmarks, training data, and evaluation workflows that show frontier AI teams what their models can actually do.

The measurement gap

Benchmarks are broken.

Frontier teams ship models against scores that no longer mean what they used to. We build evaluations grounded in the messy, ambiguous work models are actually asked to do.

01 / Saturated

Scores top out before models do.

Public benchmarks hit their ceiling within months. A 95% headline tells you little about what the next model generation will break on.

02 / Contaminated

Test sets leak into training data.

Once a benchmark is on the open web, it ends up in pre-training corpora. Models recall answers instead of reasoning toward them.

03 / Disconnected

Puzzles are not production.

Real work is ambiguous, multi-turn, and full of unstated constraints. Most evals test clean, single-shot tasks that rarely happen in practice.

Internal quality gate

Four gates. Every dataset. No exceptions.

A benchmark is only as trustworthy as its labels. Every item we ship, whether it's an eval task or a training record, passes the same four checks.

  1. 01

    Blind Re-Review

    A second expert independently re-evaluates every item without seeing the first reviewer's scores, removing single-reviewer bias.

  2. 02

    Consistency Audit

    Automated checks flag scoring outliers, incomplete rubric fields, and prompt-response mismatches across the batch.

  3. 03

    Senior Calibration

    A senior technical lead samples every batch to keep rubric interpretation consistent across reviewers and domains.

  4. 04

    Final Sign-Off

    Nothing ships until it clears all gates. Every record carries a provenance trail back to its source pull request.

Process

From signal to training-ready.

A four-stage engagement that starts with your model's gaps, not our catalogue.

01

Discover

Map your model's gaps, define target behaviors, and agree on the signals your pipeline needs.

02

Source

Extract signal from production repositories: pull requests, review cycles, and engineering decisions.

03

Evaluate

Experts write, solve, and score every item, then run it through all four quality gates.

04

Deliver

Provenance-tracked datasets and eval suites, formatted for your training and evaluation stack.

The quality of your evaluation is the ceiling on your model. Everything else is noise.

Find out what your model can actually do.

Tell us where your model is uncertain. We'll scope a pilot benchmark or dataset around it, usually within a week of our first call.
