The author tested Claude Fable 5.1 and DeepSeek 4.1 on business-plan review using AI-generated plans with planted mistakes and 31 anonymized real Regulation Crowdfunding companies scored against later outcomes, where both models caught about four in five problems (81% and 82%). The piece also reports that a model identified the real company behind 37 of 68 disguised plans, that both models flagged nearly half of real red herrings as problems, and that the tests are small, single-run signals rather than a ranking.
