- A run can be tested on twenty rows, compared across models, then expanded by removing the SQL LIMIT.
Field notes
The local setup is described as one process, one SQLite file, and one data folder, launched with uvx and opened at localhost:8000. A sample review-labeling query shows a twenty-row limit, yes/no answers, model calls, and a displayed cost; the page recommends inspecting results before removing the limit. Runs create separate datasets, with branches exportable as CSV, JSONL, or Parquet.
