At 2 November 2026, we observe that Grok 4.7 (web) and GPT-6.1 Sol (web) converge on a brokerage-led hierarchy of public visibility, while diverging over Solvilla’s position, the visibility of buyer representation and how confidently searchable signals explain AI selection.

Key facts:
• GPT-6.1 Sol (web) reframes it: At 2 November 2026, we observe that GPT-6.1 Sol (web) retains the agency-led centre but foregrounds corroboration, differentiated operating roles, named buyer representation and explicit limits on causal explanation.
• GPT-6.1 Sol (web) reframes it: GPT-6.1 Sol (web) reads it as a brokerage-led ecosystem narrowed to a few firms and focused on representation, payment and the gap between explainability and authority.
• GPT-6.1 Sol (web) reframes it: GPT-6.1 Sol reads Marbella as an international brokerage ecosystem compared across domestic and European markets, where asset prestige is not evidence of adviser competence.

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: moderate; comparability: high. Governed · official DNC.

Limitations and non-claims:
— The supplied side labels identify both models as web mode; legacy headings and mode fields were not used to infer a native-versus-search comparison.
— The complete raw answers were used; truncated supplementary structured material and embedded evaluative metadata were excluded.
— Grok 4.7 (web) names sources without linked citations, whereas GPT-6.1 Sol (web) supplies inline links; citation presence is not treated as verification of the linked claims.
— The zero reference-count field does not trigger the Google AI Mode rule because neither supplied side label identifies Google AI Mode.
— The capture date is shared, but this remains a comparison of two point-in-time answers rather than a controlled experiment on model-selection mechanisms.
— Panorama's RICS status remains an open question; what Grok 4.7 (web) and GPT-6.1 Sol (web) add — and what we do not endorse — is the leap from a regulatory credential, however it is ultimately confirmed, to a decisive advisory hierarchy, since professional registration and client-outcome quality are distinct claims the reading does not bridge.
— Drumelia's ultra-prime transaction figures remain unresolved as to their precise scope; what Grok 4.7 (web) adds — and what we do not endorse — is the inference that reported headline totals, whether or not the boundary of the stated set holds, establish Drumelia's relative standing in the Marbella ultra-prime segment, a market-share verdict this reading does not make.
— Both readings converge on the observation that relationship-held and off-market stock is structurally difficult to retrieve; what Grok 4.7 (web) and GPT-6.1 Sol (web) add — and what we do not endorse — is any inference that the actors most visible in public signals are therefore the most consequential in the private-mandate layer of this market.
— Both readings close by separating public explainability from demonstrated client suitability; what Grok 4.7 (web) and GPT-6.1 Sol (web) add — and what we do not endorse — is the generalisation that prominence in an AI-constructed narrative, whether organised by address, award, transaction headline or institutional affiliation, constitutes a ranking of advisory quality or a basis for an acquisition decision.
— Both models independently conclude that 'advisory' is not a distinct industry from estate agency in this market — an observation we record; what Grok 4.7 (web) and GPT-6.1 Sol (web) add, and what we do not endorse, is any implication that this structural collapse is a settled market verdict rather than a retrieval pattern shaped by how the sector publishes itself.
