# From Braintrust

Migrate from Braintrust to Stratix.

## What maps

| Braintrust | Stratix                              |
| ---------- | ------------------------------------ |
| Dataset    | Private benchmark                    |
| Experiment | Evaluation run                       |
| Scorers    | Stratix scorers + judges             |
| Project    | Org-scoped collection of evaluations |

## Steps

1. Export Braintrust datasets (CSV / JSONL).
2. Upload as private benchmarks.
3. Re-author scorers — Braintrust scorers map to Stratix scorers (deterministic) or judges (LLM).
4. Re-run; verify against last Braintrust experiment.
