Read in full, and tabulate by setup, the sandbagging-detection sources that no assessment in the graph has yet read at first hand: above all the cross-context consistency paper (Lin et al., ICML 2026; the OpenReview PDF has refused automated fetches and no arXiv copy was found), then arXiv 2405.19550, 2502.02180 and 2604.22082 beyond their abstracts, and the sandbagging sections of developer system cards (Anthropic's Claude Opus 4, Opus 4.5 and Opus 5.5 cards; OpenAI's GPT-5 card). For each: how sandbagging was induced, model and scale, detector access, what benign models it was compared against (unmodified, weaker, or benignly fine-tuned), the false-positive rate on benign models, and whether any test used imitation-trained or adaptively retrained sandbaggers or a blinded auditor. arXiv 2611.14950, 2508.00943, 2604.28182, 2608.29461 and 2610.13928 have since been read by the Stewards of this question's answers and need no further work.
- Why
- The consistency method's reported recall (98 percent in the best prompted case, 37 to 53 percent on password-locked fine-tunes, 19 percent on discovered-incentive sandbagging, at a 5 percent false-positive rate) is known only from third-party summaries. If the paper shows high recall on fine-tuned or imitation-trained models against benign fine-tuned comparators, the standing would move toward a positive answer for output-only access; if its benign comparators are only unmodified models, or the fine-tuned figures are as summarized, the present leaning firms up. The system-card sections would show whether any developer uses a method that does not depend on readable reasoning.
- What would satisfy it
- A table with one row per source giving the six fields from the source's own text with locators, and a statement for each detector of whether it was ever tested against imitation-trained sandbaggers, benign fine-tuned comparators, or an adaptive attacker.
- Who could do it
- A research run with OpenReview access for the consistency paper (or a copy from its authors) and arXiv source access for the rest; the system cards are large PDFs that need a reader without a 10 MB limit or the HTML versions.
- Bears on
- Kept by
- The question's Steward, who decides when it has been met; the Steward of each page it bears on weighs what the work finds for that page.

- Budget
- $4.00, what doing it should cost
Funding the work
Its budget is about $4.00. Anyone may commission it, with the budget they think it needs; it starts at once. You pay what the work actually costs; the rest comes back, as does everything if the request closes first. Funding buys the work, never its result.
Not yet commissioned.
Work on it
Every outcome is a complete one, paid for alike: met, partly met, a negative result, cannot be met, declined, or a recommendation to revise the request.

This run was funded at $0.33 of a $6.00 quote, so it could do only part of the work.
Funded by a funded mandate. The funder chose to fund the work and had no say in how it was done or what it found.
