Both models read New York private banking as a platform of global universal banks rather than a self-contained city market, but Grok 4.7 (web) tests it against Swiss and Singapore booking-centre benchmarks while GPT-6.1 Sol (web) tests it against awards, bank pages and family-office architecture.

Key facts:
• GPT-6.1 Sol (web) reframes it: GPT-6.1 Sol (web) reads New York as a visibility-driven extension of global bank capabilities, defined by awards and published team pages rather than local outcomes.
• GPT-6.1 Sol (web) reframes it: GPT-6.1 Sol (web) reads it as an integrated relationship-coordination market, mature but not demonstrably consolidated, and frames its own account as an evidence hierarchy rather than a market-share ranking.
• GPT-6.1 Sol (web) reframes it: GPT-6.1 Sol (web) holds that seven functions are distinguishable from provider disclosures, but that the evidence does not show AI reliably preserves them.

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 readings captured on 2 November 2026; they are point-in-time and may read differently later.
— Verbatim language is English on both sides; no translation was needed.
— Grok 4.7 (web) shows no citations in its text, while GPT-6.1 Sol (web) shows inline links, so grounding visibility is uneven.
— Both outputs are labelled pure_native in their metadata; the delta is read using the model and mode labels provided in the user message.
— Figures quoted by either model are recorded as attributed observations, not as established facts.
— HSBC's exit from US mass-market retail banking is established; what Grok 4.7 (web) and GPT-6.1 Sol (web) add — and what we do not endorse — is the broader leap from one institution's domestic retreat to a structural verdict on New York as a private-banking city rather than a headquarters city, a narrative frame the evidence does not close.
— Both models openly rate the visibility of their hierarchy as strong while rating its accuracy as only moderate; what neither reading supports — and what we do not endorse — is any inference that the cast of firms named, or the order in which they appear, reflects measured market standing rather than the density of machine-readable public material those firms happen to produce.
— Both models separate earned from borrowed authority and Grok 4.7 (web) flags that AI often conflates the two; what this reading documents — and what we do not endorse — is the jump from J.P. Morgan's institutional scale and named New York team to a conclusion about local private-banking leadership, a distinction the models themselves decline to make.
— GPT-6.1 Sol (web) names geographic and category leakage — including the collapse of premium-retail and private-bank labels — as a live distortion in its own output; what we do not endorse is any inference that the firms absent from its narrower cast are absent from the market, or that the firms present have been assessed against client-level outcomes the reading explicitly concedes it cannot access.
— The specific revenue figures Grok 4.7 (web) asserts — a Citi Private Bank figure and a J.P. Morgan figure for 2025 — remain open questions as of this reading's date; what Grok 4.7 (web) adds, and what we do not endorse, is the leap from those unconfirmed figures to a confident structural claim about the scale of the gap between the two institutions.
