Terminal-Bench
Agentic terminal tasks. Epoch publishes one row per agent harness; the best score per model is kept, because the harness is not a property of the model. Aggregated from Epoch AI's AI Benchmarking Hub (terminalbench_external.csv, column 'Accuracy mean'), used under CC-BY 4.0. The Known Good aggregates published results; it runs no evaluations.

The Known Good
Provenance. These figures are published by Epoch AI and redistributed here under CC-BY 4.0.
The publisher's own page is here. We did not run this evaluation and we do not adjust the published numbers — where a score feeds an index it is
min-max normalised against every other model holding the same evaluation, and nothing else is done to it.
This evaluation is one of the seven components of the
Known Good Index. Full licence detail is on attribution, and every score here is
in the CSV download.
