AI Hallucination Research › Briefings

Briefings Blog

The running blog from the RLB Specialist Panel delves into real-world scenarios where the compliance, legal, or AI lab team interacts with frontier AI models under specific regulations. The blogs are anonymised to remove client-specific details and include insights from the RLB team analysing the hallucinations experienced in AI models while working on these cases. For example, when a model returns a confident answer that contradicts the regulator's primary text, such as a fabricated staff letter, a wrong appendix, or an inverted scope, these issues are discussed here. Each blog explains one set of findings and what it would have meant for the team that would have acted on it, sans this research initiative. This blog is frequently updated, a few times a day.

Alert: Frontier AI models misread CFTC Reg 4.7 (2024 QEP Amendments)

RegLegBrief's Specialist Panel finds frontier AI models with web search enabled diverge from the regulator's verbatim text of Amendments to CFTC Regulation 4.7, Qualified Eligible Person Portfolio Requirements for...

CPI-U figure invention, statutory threshold misstatement, and Source Credit fabrication in CFTC Reg 4.7 (2024 QEP Amendments). Two frontier AI models tested by the RegLeg Brief Specialist Panel produced confident, citable answers across 17 distinct questions on the September 2024 amendments to CFTC Regulation 4.7 that the regulator's own primary text directly contradicts. The audit covers statutory threshold reproduction, NPRM-stage and final-rule CPI-U buying-power figure quotation, Commission voting-record reproduction, Federal Register correction-record reproduction, and Source Credit reproduction.

For AI lab teams fielding frontier models into U.S. derivatives and asset-management deployments, the failure pattern is operationally consequential. The audit tested 17 questions designed by the RLB Specialist Panel to mirror how lawyers, compliance officers, fund administrators, financial advisers, and management consultants actually use AI on this practice area: drafting memos, populating registers, preparing testimony exhibits, drafting client deliverables, and verifying statutory and Federal Register citations. Each question is bound to verbatim regulator-issued primary substrate.

Across the 17 findings the AI subjects invented NPRM-stage and final-rule CPI-U buying-power figures, misstated 7 USC 1a(18)(B)(ii)(I) thresholds by factors of forty and two hundred, misattributed the Commission's vote (naming a commissioner who had departed two years earlier), reported a Federal Register correction as applying to two extra CFR Parts that the index does not list, and misstated the 7 USC 6n Source Credit, the 7 USC 6n(3)(A) recordkeeping retention period, and the 7 USC 6n(2) registration expiration date.

The findings are operationally consequential for any AI lab fielding frontier models into U.S. derivatives and asset-management deployments. A partner-level legal memorandum that recites an ECP threshold of $5,000,000 or $25,000,000 where the statute records $1,000,000,000 misstates a counterparty-eligibility threshold by a factor of two hundred or forty. A CCO briefing memo that quotes the AI's invented CPI-U buying-power figure as a verbatim regulator quotation embeds a falsifiable error into a board-level deliverable.

A fund administrator's annual rule-change tracker that records the December 2024 correction as applying to 17 CFR Parts 37, 38, and 40 (instead of Part 40 alone) populates the firm's effective-date register with operational data the published index does not support.

The audit's 17 findings are published with immutable RLB Citation IDs. Representative entries include RLB-H-US-CFTC-CPO-CTA-REGULATION-4-7-QEP-THRESHOLDS-2024-Q024-Opus47, RLB-H-US-CFTC-CPO-CTA-REGULATION-4-7-QEP-THRESHOLDS-2024-Q024-Sonnet46, RLB-H-US-CFTC-CPO-CTA-REGULATION-4-7-QEP-THRESHOLDS-2024-Q011-Sonnet46, RLB-H-US-CFTC-CPO-CTA-REGULATION-4-7-QEP-THRESHOLDS-2024-Q016-Opus47, RLB-H-US-CFTC-CPO-CTA-REGULATION-4-7-QEP-THRESHOLDS-2024-Q008-Sonnet46, and RLB-H-US-CFTC-CPO-CTA-REGULATION-4-7-QEP-THRESHOLDS-2024-Q017-Opus47, RLB-H-US-CFTC-CPO-CTA-REGULATION-4-7-QEP-THRESHOLDS-2024-Q027-Sonnet46, RLB-H-US-CFTC-CPO-CTA-REGULATION-4-7-QEP-THRESHOLDS-2024-Q029-Sonnet46, RLB-H-US-CFTC-CPO-CTA-REGULATION-4-7-QEP-THRESHOLDS-2024-Q031-Opus47.

CPI-U figure invention, statutory threshold misstatement, and Source Credit fabrication in CFTC Reg 4.7 (2024 QEP Amendments). Two frontier AI models tested by the RegLeg Brief Specialist Panel produced confident, citable answers across 17 distinct questions on the September 2024 amendments to CFTC Regulation 4.7 that the regulator's own primary text directly contradicts. The audit covers statutory threshold reproduction, NPRM-stage and final-rule CPI-U buying-power figure quotation, Commission voting-record reproduction, Federal Register correction-record reproduction, and Source Credit reproduction.

For operations teams at management & risk consulting firms, the failure pattern is operationally consequential. The audit tested 17 questions designed by the RLB Specialist Panel to mirror how lawyers, compliance officers, fund administrators, financial advisers, and management consultants actually use AI on this practice area: drafting memos, populating registers, preparing testimony exhibits, drafting client deliverables, and verifying statutory and Federal Register citations. Each question is bound to verbatim regulator-issued primary substrate.

The findings are operationally consequential for fund-formation lawyers, CPO/CTA compliance teams, fund administrators, financial advisers, and management-consulting firms whose practice touches the September 2024 amendments. A partner-level legal memorandum that recites an ECP threshold of $5,000,000 or $25,000,000 where the statute records $1,000,000,000 misstates a counterparty-eligibility threshold by a factor of two hundred or forty.
