Eval Harness First

Build the evaluation harness that gates every fine-tuning run — golden sets, per-failure-mode graders, judge calibration, and base-model baselines. Use when starting a fine-tuning effort, when converting traces into an eval set, or when calibrating a judge against human labels.

Frequently asked questions

What does Eval Harness First do?

Build the evaluation harness that gates every fine-tuning run — golden sets, per-failure-mode graders, judge calibration, and base-model baselines. Use when starting a fine-tuning effort, when converting traces into an eval set, or when calibrating a judge against human labels.

Is Eval Harness First free to use?

Yes. Eval Harness First is published by Seth Hobson under the MIT licence, and you can use it with a free Phở account.

How do I use Eval Harness First in Phở?

Press Open in Phở, then Try to apply it to your next message, or add the LLM apps and fine tuning set so Phở loads it whenever a request matches.

Does Eval Harness First need other tools?

No. It works in a normal Phở chat with what you type or upload.
