GPT-6.1 Sol (native) and GPT-6.1 Sol (web) share the same cast and the same Swiss benchmark. The native reading rests on category associations and warns that 'visibility becomes authority'. The web reading anchors the same frame in published thresholds, a Deloitte ranking and a dated tax-regime change.

Key facts:
• GPT-6.1 Sol (web) reframes it: GPT-6.1 Sol (web) keeps the same core cast but anchors it in published thresholds, Deloitte and Chambers material and a dated tax change, and warns about metric substitution.
• GPT-6.1 Sol (web) reframes it: GPT-6.1 Sol (web) argues the same substitution but anchors it in specific provider thresholds, regulatory dates and operational disclosures, calling for a conditional relationship map.
• GPT-6.1 Sol (web) reframes it: GPT-6.1 Sol (web) keeps the same institution-first logic but anchors it in cited bank pages, the FCA, Chambers and a dated impersonation report, with Arbuthnot Latham replacing HSBC.

Reading basis: Model Watch — a Deep Narrative Capture dual: 6 DNC prompts asked to GPT-6.1 Sol (native) 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:
— Neither reading supports a client-outcome or market-share ranking, and both say so themselves.
— GPT-6.1 Sol (web) draws London conclusions from UK-wide aggregates and says so, so city-level inferences stay limited.
— The figures and dates in GPT-6.1 Sol (web), including thresholds and the tax-regime change, are recorded as the model's own claims and not as established facts.
— The two readings do not rest on equal evidence: native states it had no search results or provider documents, while web draws on retrieved pages, so some divergence reflects evidence access rather than model reasoning.
— Web's figures and dates are attributed to provider pages and the readings carry no independent second source in the text, so they remain unverified here.
— No judgment on whether either reading is more accurate about the London market.
— No claim that any named bank outperforms another.
— No assertion that the web reading is superior to the native reading.
— No inference about why HSBC is absent from the web reading.
— No ranking or judgement of Coutts, C. Hoare & Co, UBS, Barclays Private Bank or Nedbank Private Wealth is made.
