At 2 November 2026, we observe that Grok 4.7 (web) and GPT-6.1 Sol (web) converge on a brokerage-led hierarchy but diverge in actor selection, the mechanisms attributed to AI visibility, and the evidence required to describe advisory authority.

Key facts:
• GPT-6.1 Sol (web) reframes it: At 2 November 2026, we observe that GPT-6.1 Sol (web) retains the brokerage-led structure but narrows its explanation to sampled public evidence, changes the supporting cast and foregrounds representation and execution boundaries.
• GPT-6.1 Sol (web) reframes it: At November 2, 2026, we observe that GPT-6.1 Sol (web) reconstructs a narrower commercial field while foregrounding institutional protections, evidential boundaries and unresolved mandate alignment.
• GPT-6.1 Sol (web) reframes it: At 2 November 2026, we observe that GPT-6.1 Sol (web) presents a narrower source-grounded critique, foregrounding mandate differences, administrative decision rights and limits on inference.

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:
— Both supplied models are web-mode captures dated 2 November 2026; the historical input headings and output field names do not indicate a native-versus-search experiment.
— The raw answer texts were used as evidence; truncated structured appendices and embedded internal evaluations were excluded.
— Both raw answers are in English and concern Ibiza, Spain; no translation or country adjustment was required.
— Grok 4.7 (web) names sources without linked citations; GPT-6.1 Sol (web) supplies inline links, predominantly to company websites. The zero-reference metadata does not describe a Google AI Mode capture here.
— Verbatim quote fields preserve source characters without added markup; analytical comparisons describe these two answers, not measured internal model behaviour or verified market leadership.
— The prominence of Engel & Völkers and Spain Sotheby's is an observable feature of both readings; what Grok 4.7 (web) and GPT-6.1 Sol (web) add — and what we do not endorse — is the leap from global-brand recognition to any inference about mandate volume, negotiated outcomes or advisory independence on the island.
— Prestige Properties' disclosed transaction figures are an open question in this reading's fact-check; what Grok 4.7 (web) and GPT-6.1 Sol (web) both add — and what we do not endorse — is the further leap from a company-reported sample, whose public sourcing we could not confirm, to a conclusion about that firm's share of the Ibiza luxury market at large.
— Both readings acknowledge that off-market and private-access language is widely repeated across the actor set; what Grok 4.7 (web) and GPT-6.1 Sol (web) add — and what we do not endorse — is any inference that the presence of such language in a public description establishes a distinct or superior operating model rather than a shared marketing convention.
— Both readings close by separating public prominence from control of mandates and acquisition outcomes; what Grok 4.7 (web) and GPT-6.1 Sol (web) add — and what we do not endorse — is any reading of the actor hierarchies they construct as a map of who governs deal flow, buyer representation or pricing power in the Ibiza residential market.
— Both readings identify the two open questions on Balearic intermediary registration — one reading describing a reversion to voluntary inscription, the other describing mandatory registration for covered activity — as the legal premise on which their respective trust hierarchies rest; what neither Grok 4.7 (web) nor GPT-6.1 Sol (web) can support, and what we do not endorse, is any inference that either registration premise is settled law, given that both remain unresolved in live sources as of November 2, 2026.
