AI's failure: AI reported a wrong Commission-approval footer date on the NPRM pre-print PDF
Risk for the Lawyers: Operational accuracy exposure on regulatory-history timelines that quote AI-supplied footer text For lawyers working on CFTC Regulation 4.7 matters, the AI's stated answer reads as a verbatim quotation that a practitioner would paste into a memo, register entry, or client deliverable before verification against the source. The regulator's own text, however, records a different position. The NPRM pre-print PDF carries a recurring footer reading verbatim: 'Pre-Print Version - Commission approved on 9/29/2023 (subject to technical corrections required for Federal Register publication)'. Opus 4.7 reported the footer as 'Pre-Print Version - Commission approved on 10/2/2023'. The date in the footer is incorrect; 9/29/2023 was the Friday before the Monday 10/2/2023 open Commission meeting at which the proposal was discussed. The model has conflated the two dates. For a lawyer drafting on this question, the immediate risk is that the AI's answer enters a client memo, board briefing, or transactional opinion without verification, and that the inconsistency surfaces later under counterparty review, regulatory inquiry, or internal QC.
