Grok 4.7 (web) and GPT-6.1 Sol (web) agree on the core blind spot: AI's picture of Luxembourg private banking rests on highly retrievable institutional sources. They diverge on what that hides. Grok 4.7 stresses the ownership split between booking centre and relationship centre, plus a cast of unnamed wrapper insurers, external managers and service providers. GPT-6.1 Sol stresses legal-entity precision, access conditions and the gap between a documented capability and a deliverable relationship.

Key facts:
• GPT-6.1 Sol (web) reframes it: GPT-6.1 Sol (web) says AI turns institutional positioning into apparent consensus and omits access conditions, legal-entity distinctions, structuring-protection interplay and the line between capability and a deliverable relationship.
• GPT-6.1 Sol (web) reframes it: GPT-6.1 Sol argues that AI can recognise seven functions but misallocates responsibility when it follows brand narratives instead of mandates and regulatory categories.
• GPT-6.1 Sol (web) reframes it: GPT-6.1 Sol (web) frames Luxembourg as a cross-border wealth-management system with differentiated delivery models, and cautions that visibility, economic importance and client suitability are three separate hierarchies.

Reading basis: Model Watch — a Deep Narrative Capture dual: 6 DNC prompts asked to Grok 4.7 (web) and to GPT-6.1 Sol (web), each pair reconciled by a delta synthesis and left uncorrected. Every framing is the AI's own — the models speaking, not an Observatory measurement. Confidence: high; comparability: high. Governed · official DNC.

Limitations and non-claims:
— Both sides are web mode, so ai_mode_no_citations does not apply; Grok 4.7 (web) shows no URLs while GPT-6.1 Sol (web) shows inline links.
— Verbatim language is English on both sides.
— Both readings are point-in-time (2 November 2026) and describe 2024 data largely from 2025 reports.
— The AML ratings quoted by each side may measure different things (residual versus inherent); do not read them as direct contradiction.
— Neither side discloses the outputs of any AI system it criticises; claims about AI behaviour are the models' own characterisations.
— The consolidation figures — 66 banks in 2015 to 42 by 2024 — remain an open question rather than a verified count; what Grok 4.7 (web) adds, and what we do not endorse, is the leap from that unconfirmed trajectory to a settled industrial narrative about the structural consequences of scale pressure in Luxembourg private banking.
— Both models surface the KPMG beneficial-owner caveat on life-insurance wrappers as an established methodological point in the literature; what Grok 4.7 (web) and GPT-6.1 Sol (web) add — and what we do not endorse — is the inference that this caveat materially recharacterises the headline AuM figure, a conclusion that would require independent quantification of wrapper-domiciled assets that neither reading supplies.
— The personnel-cost differential between Luxembourg and Switzerland remains an open question with no conclusive public confirmation; what Grok 4.7 (web) adds — and what we do not endorse — is the use of that unverified ratio as a comparative business-model verdict, treating a figure of uncertain provenance as though it settles the question of how Luxembourg's cost structure positions it against its principal competitor.
— GPT-6.1 Sol (web) alone makes explicit that its claims are inferences from public-source retrieval, and Grok 4.7 (web) names an epistemic limit on AI sourcing at large; what both readings add — and what we do not endorse — is any implication that this self-audit resolves the underlying gap, since the operating detail that neither model can retrieve from reusable authoritative figures is precisely the detail that the self-diagnosis identifies as missing.
— The open-question status of Luc Rodesch's attributed statement is established; what Grok 4.7 (web) adds — and what we do not endorse — is the leap from one practitioner's unverified interview remark to a market-wide rule that AI may treat as definitional, collapsing the semantic distinction between private banking and wealth management across the entire Luxembourg landscape.
