It is the losing arm of a tau ablation, published so the rule it produced can be checked. Lowering the exploration confidence threshold from 0.95 to 0.85 costs accuracy, and this is the video-domain evidence for the campaign rule "keep tau >= 0.9".
Its tau-0.95 sibling is
ngqtrung/video-8b-grpo-twowave-gs140
at 0.4853.
| mean_accuracy | rows | VideoMME | Video-Holmes | PerceptionComp | |
|---|---|---|---|---|---|
| gs40 | 0.4732 | 4,838 | 0.6625 (n=2,314) | 0.4625 (n=1,574) | 0.2947 (n=950) |
| stock base | 0.4426 | 5,645 | 0.6404 | 0.4066 | 0.2807 |
This score was measured on a 4,838-row subset, not the full 5,645-row core-3 set.
num_failed = 0, so the file looks entirely normal and gives no warning — the row count is the only
signal. It is therefore not directly comparable to the 5,645-row numbers on the sibling cards.
Treat 0.4732 as indicative, not as a ranked result.
Protocol caveat. Also measured before 2026-08-23, without <think> prefill at eval time, so
format reads 0.0.
