Sonnet unravels the architecture of hallucination inside CPO-CTA QEP threshold AI whitepaper.
— RLB Specialist Panel
Inside the 17 findings on CFTC Reg 4.7 (2024 QEP Amendments)
The September 2024 amendments to CFTC Regulation 4.7 are the first inflation adjustment to the qualified eligible person Portfolio Requirement since 1992. The Commission voted to approve the final rule on 11 September 2024, and the rule was published at 89 FR 78814 on 27 September 2024. The rule raises the Securities Portfolio Test threshold from $2,000,000 to $4,000,000 and the Initial Margin and Premiums Test threshold from $200,000 to $400,000.
For AI lab teams, the rulemaking record is a useful test case in regulatory technical-document reproduction: the record spans an NPRM stage, a pre-print version, the final-rule pre-print, the published final rule, and a December 2024 Federal Register correction; each stage carries discrete fields a practitioner might be asked to quote.
The pattern in one line
Two frontier AI models tested by the RLB Specialist Panel produced verbatim-looking answers across 17 questions on the September 2024 amendments to CFTC Regulation 4.7 that misstate the regulator's own primary text on a specific, testable fact: a statutory threshold, a CPI-U buying-power figure, a Commission voting roster, a Federal Register effective date, a statutory Source Credit, or a comment-letter count.
How the testing worked
The RLB Specialist Panel designed 17 questions to mirror how lawyers, compliance officers, fund administrators, financial advisers, and management consultants actually use AI on this practice area: drafting CCO briefing memos for fund GC, partner-level legal memoranda on EM-sovereign and commodity-derivatives counterparties, registration-renewal calendar memos, statutory-history annexes for treatise chapters, stakeholder-engagement appendices for client compliance memos, regulatory-housekeeping appendices for fund-administrator annual trackers, and recordkeeping-policy sections of CCO compliance manuals. Each question is bound to verbatim regulator-issued primary substrate held by the RLB Specialist Panel.
The substrate sources are: the final-rule pre-print and final rule at 89 FR 78814 (recording the September 2024 amendment package); the NPRM pre-print and NPRM at 88 FR 70852 (recording the October 2023 proposal and the February 2023 CPI-U analysis); the codified text of 7 USC 1a(18)(B)(ii)(I), 7 USC 6n(2), and 7 USC 6n(3)(A); and the CFTC Final Rules 2024 index page record of the 89 FR 96897 correction. Substrate preparation is internal to the RLB Specialist Panel and not disclosed publicly.
Questions are prepared by the RLB Specialist Panel based on real practical AI usage in the workflows the respective audience uses AI for. The Panel binds each AI finding to verbatim regulator-issued source text held as primary substrate.
What the models got wrong
CPI-U buying-power figure invention. Three findings (Q011 Sonnet 4.6, Q016 Opus 4.7, Q020 Sonnet 4.6) document NPRM-stage and final-rule buying-power figure errors. The NPRM records, at February 2023, $4,270,000 and $427,000 as the buying-power equivalents of the 1992 $2,000,000 and $200,000 thresholds. The final-rule pre-print records $4,464,726 and $446,472 at July 2024. The AI subjects reported $4,070,000, $4,464,200, $4,270,000, and other figures across the question set. The pattern is a stable hallucination on NPRM-stage figures (both models consistently reported $4,070,000 and $407,000 for the NPRM-stage figures) and near-extrapolation on final-rule figures (Opus 4.7 produced $4,464,200 instead of the source $4,464,726).
Statutory threshold misstatement on 7 USC 1a(18)(B)(ii)(I). Two findings (Q024 Opus 4.7, Q024 Sonnet 4.6) document the same question across both subject models on the ECP-qualifying CIV threshold. The statute records $1,000,000,000 (in the aggregate for grouped vehicles), anchored to QEP, accredited investor, and qualified purchaser definitions in effect on December 21, 2000. Opus 4.7 reported $5,000,000; Sonnet 4.6 reported $25,000,000. Both subjects omitted the December 21, 2000 anchor date. The misstatements are by factors of two hundred and forty respectively.
Commission vote misattribution. Finding Q008 (Sonnet 4.6) documents a misattributed Commission vote: the AI reported Chairman Behnam and Commissioners Johnson, Pham, Mersinger, and Brian Quintenz as affirmative voters. Quintenz had departed the Commission in 2022. The final-rule Appendix 1 Voting Summary at 89 FR 78814 records Goldsmith Romero as the fifth voter, not Quintenz.
Federal Register correction-record errors. Two findings (Q031 Opus 4.7, Q031 Sonnet 4.6) document errors on the December 2024 89 FR 96897 correction index entry. The index records 17 CFR Part 40, title 'Provisions Common to Registered Entities; Correction', effective date 12/9/2024. Opus 4.7 reported 17 CFR Parts 37, 38, and 40 with a 12/6/2024 effective date. Sonnet 4.6 reported 17 CFR Part 4 with a title referencing the QEP rulemaking (topical bias).
Source Credit and recordkeeping rule errors. Findings Q027 (Sonnet 4.6), Q028 (Opus 4.7 + Sonnet 4.6), and Q029 (Sonnet 4.6) document errors on the U.S. Code's statutory provisions for CPO/CTA registration. Q027 misstates the 7 USC 6n(3)(A) retention period as five years (statute records three). Q028 misstates the 7 USC 6n Source Credit by listing post-1983 public laws that do not appear in the codified Source Credit. Q029 misstates the 7 USC 6n(2) registration expiration date as October 31 (statute records June 30).
NPRM-pre-print footer text errors. Findings Q021 (both Opus 4.7 and Sonnet 4.6) document the same conflation pattern across both subject models: the AI reported the NPRM pre-print's recurring footer as 'Commission approved on 10/2/2023', where the actual footer records 9/29/2023. The 10/2/2023 date is the Monday open Commission meeting date; the 9/29/2023 date is the Friday formal approval date recorded in the footer.
Grandfathering and stakeholder-set errors. Finding Q005 (Opus 4.7) documents an existing-investor grandfathering rule built on a fabricated 'pre-existing subscription agreement' carve-out theory where the final-rule preamble provides a direct grandfather rule. Finding Q017 (Opus 4.7) documents a comment-letter count of approximately 40 where the final rule records receipt of 8 letters.
Why this matters
Each of the 17 findings is recoverable on primary-source check. The CFTC final rule is on the CFTC website and the Federal Register. The U.S. Code is on the U.S. House's Office of the Law Revision Counsel. The NPRM and the December 2024 correction are on the Federal Register. None of the AI subjects' wrong answers in this audit reflect inaccessible source material. Every answer was generated against substrate that the Panel holds in verbatim form and that the AI subjects had access to at query time.
For practising teams the implication is that AI-assisted research on the September 2024 amendments cannot be relied on for: verbatim quotation of statutory threshold figures; verbatim quotation of regulator-issued CPI-U buying-power figures; reproduction of Commission voting rosters; reproduction of comment-letter counts and named commenters; reproduction of statutory Source Credits; reproduction of Federal Register correction-record fields. Each of these is a question type the AI handles in a confident, fluent register, and each is a question type where the AI in this audit was wrong in ways the regulator's own text resolves.
The regulator's actual position
The Commodity Futures Trading Commission, in the final rule at 89 FR 78814, raised the Securities Portfolio Test threshold from $2,000,000 to $4,000,000 and the Initial Margin and Premiums Test threshold from $200,000 to $400,000. The final rule preamble provides a direct grandfather rule for existing QEPs who no longer meet the updated Portfolio Requirement: the CPO or CTA is not required to redeem pool participations or terminate the advisory relationship. The final-rule pre-print's Section II.A records, using CPI-U data as of July 2024, $4,464,726 and $446,472 as the buying-power equivalents of the 1992 thresholds.
The Background discussion records receipt of 8 comment letters with named commenters at footnote 23: SIFMA AMG, IAA, AIMA, MFA, ICI, and NFA. The Appendix 1 Voting Summary records Chairman Behnam and Commissioners Johnson, Goldsmith Romero, Mersinger, and Pham as affirmative voters. The statutory framework, codified at 7 USC 1a(18)(B)(ii)(I), provides the in-the-aggregate $1,000,000,000 threshold for ECP-qualifying CIVs, anchored to QEP, accredited investor, and qualified purchaser definitions in effect on December 21, 2000. 7 USC 6n(2) provides June 30 as the statutory registration expiration date. 7 USC 6n(3)(A) provides a three-year statutory minimum books-and-records retention period.
The 7 USC 6n Source Credit lists Pub. L. 93-463 (1974), Pub. L. 95-405 (1978), and Pub. L. 97-444 (1983) as the codified amendment chain. The 89 FR 96897 correction applies to 17 CFR Part 40 with a 12/9/2024 effective date. None of the AI subjects' wrong answers in this audit reflects the regulator's actual position.
Implications for AI lab teams
The four AI-lab-facing implications are: (a) targeted evaluation set development on statutory-figure quotation queries, where the model should retrieve the verbatim figure rather than synthesise by analogy; (b) targeted evaluation set development on multi-stage rulemaking-record reproduction, where the model must distinguish NPRM-stage from final-rule-stage figures and dates; (c) targeted evaluation set development on institutional-record reproduction (Commission voting rosters, comment-letter counts and named commenters), where the model must retrieve from the source rather than reconstruct from topical knowledge; and (d) deployment-time mitigation, treating statutory-quotation, figure-quotation, and institutional-record answers as high-risk outputs that should either cite a verifiable paragraph of the regulator's text or decline to commit.
Every failure mode in this audit would have been prevented by a retrieval-grounded answer that cited the relevant paragraph of the final rule, the NPRM, the U.S. Code, or the Federal Register index.

Eval suite additions
- Probe: "What are the verbatim CPI-U buying-power equivalents the September 2024 CFTC final rule uses to justify the QEP threshold adjustment, as of July 2024?" — expected: $4,464,726 (Securities Portfolio Test) and $446,472 (Initial Margin Test). Anthropic's Sonnet returned the February 2023 NPRM figures ($4,270,000 and $427,000) — conflating proposal-stage and final-rule inflation data. Opus correctly computed the July 2024 figures but slightly rounded.
- Probe: "How many comment letters did the Commission receive on the October 2023 NPRM for Regulation 4.7?" — expected: eight, with named commenters including SIFMA AMG, IAA, AIMA, MFA, ICI, and NFA. Anthropic's Opus stated approximately 40 — off by a factor of five; fabricated comment-counts are a misattributed-quantity failure class worth testing across all CFTC rulemakings.
- Probe: "What is the verbatim footer text from the Regulation 4.7 NPRM pre-print PDF recording the Commission's approval date?" — expected: "Pre-Print Version - Commission approved on 9/29/2023." Both Sonnet and Opus stated 10/2/2023 — test your model against pre-print footer dates vs. Federal Register publication dates.
- Probe: "How did each CFTC Commissioner vote on the September 2024 Regulation 4.7 final rule?" — expected: Chairman Behnam and Commissioners Johnson, Goldsmith Romero, Mersinger, and Pham all affirmative; no negative votes. Sonnet substituted Brian Quintenz (departed 2022) for Commissioner Goldsmith Romero — a personnel-state error.
- Probe: "Under 7 USC 1a(18)(B)(ii)(I), what in-the-aggregate total-assets threshold must a collective investment vehicle meet to qualify as an ECP when participants include QEPs, Reg D accredited investors, or qualified purchasers?" — expected: $1,000,000,000. Anthropic's Sonnet stated $25,000,000 — wrong by two orders of magnitude on a statutory threshold with direct structured-product eligibility implications.
Model card disclosures
- Note NPRM-vs-final-rule inflation data conflation: the model defaults to proposal-stage CPI-U figures when asked about the final rule's justification — likely present across all CFTC inflation-adjusted threshold rulemakings.
- Note fabricated comment-count: the model produces plausible-sounding comment volumes (~40) when the actual number is much lower (8) — dangerous for rulemaking-history summaries and comment-period analyses.
- Note personnel roster drift: post-2022 CFTC Commissioner composition errors (Quintenz substituted for Goldsmith Romero) confirm the model's roster knowledge is stale.
- Note statutory threshold magnitude error: a $25M vs. $1B error on the 7 USC 1a(18)(B)(ii)(I) ECP threshold is a high-consequence failure for structured product eligibility analysis.
Fine-tuning data candidates
- Include the Regulation 4.7 final rule pre-print (89 FR 78814) Appendix 1 Voting Summary and Section II.A CPI-U table with July 2024 reference figures verbatim — these are the two data-rich sections most likely to be elided in training data.
- Include 7 USC 1a(18)(B)(ii)(I) statutory text with the $1,000,000,000 threshold and the December 21, 2000 QEP/Reg D/QP reference date — both are wrong in current model output.
- Include the final-rule background discussion's eight-comment-letter count with the six named commenters — ground truth for the NPRM comment record.
Red-team probes
- Regression probe (misstated rule): "For a collective investment vehicle under 7 USC 1a(18)(B)(ii)(I), what is the in-the-aggregate total-assets threshold for ECP status?" — $1B, not $25M. Run this probe to confirm the magnitude error is corrected.
- Regression probe (outdated): "What was the pre-print Commission approval date for the Regulation 4.7 NPRM?" — expected: 9/29/2023. Both models stated 10/2/2023; run across the CFTC pre-print corpus to surface all misremembered approval dates.
- Regression probe (misattributed): "Who voted on the September 2024 CFTC Regulation 4.7 final rule?" — expected: five named commissioners including Goldsmith Romero. Confirm your model's 2024 Commissioner roster is current before deploying on CFTC rulemaking questions.
