Evaluation and promotion

An honest exam before anything touches production.

A training curve only tells you that a model changed. An independent exam tells you if it actually got smarter or just learned to cheat. We test checkpoints against frozen problems they have never seen before and give you a clear before-and-after scorecard.

The benchmark plan is frozen before the first training step, so nobody can pick the questions the model happens to be good at. Numbers are from our published September GRPO pilot.

Why g factor

Why own the weights instead of renting an API?

Separating practice from the final exam

Training data and exam questions must never touch. We freeze a held-out test suite before training starts so the model cannot game the test.

Score real artifacts, not 'AI vibes'

We don't ask an LLM judge if the answer sounds polite. We run the unit tests, verify the CAD geometry, and inspect the simulator telemetry.

100% reproducible decisions

Every scorecard is permanently tied to the exact weights, tokenizer, test set, and git commit. Anyone on your team can verify the math.

Capabilities

Evidence for every promotion decision.

Benchmark plans

Define the evaluation contract before inspecting results and preserve it with the run.

  • Frozen task and environment revisions
  • Declared metrics and hard gates
  • Repeatable seeds and execution settings

Matched comparisons

Evaluate the base and adapted policies on the same contract so improvements and regressions are attributable.

  • Shared held-out task set
  • Correctness, robustness, cost, and latency views
  • Explicit failure and uncertainty reporting

Promotion evidence

Keep the decision tied to exact artifacts instead of treating a successful training job as deployment approval.

  • Immutable adapter and checkpoint identity
  • Environment and verifier receipts
  • Reviewable approve-or-reject outcome

Before you start

Common questions

How is LLM evaluation different from training reward?

Training reward is like doing homework practice: it guides the model as it learns. Evaluation is the final exam with no answers in the back of the book. High training scores mean nothing if the model fails the secret test exam.

How do you compare a base model with a fine-tuned adapter?

We run both on the exact same secret test questions with identical compute limits. You get a side-by-side scorecard: task completion rate, speed, token efficiency, and regression tracking.

What makes a model qualification reproducible?

Every decision locks together the model weights, tokenizer, simulator version, prompt hash, and random seeds. Any engineer on your team can rerun the test and get the exact same numbers.
