The two models diverge significantly in their framing of the Ibiza luxury real estate market, with GPT-4o emphasizing established agencies and Sonar Pro highlighting a fragmented, relationship-driven market.

Key facts:
• Sonar Pro (web) reframes it: Sonar Pro highlights a fragmented, relationship-driven market.
• Sonar Pro (web) reframes it: Sonar Pro (web) frames the market as a high-value, internationally oriented island property market.
• Sonar Pro (web) reframes it: Sonar Pro emphasizes visibility and institutional legibility in the Ibiza luxury real estate market.

Reading basis: Model Watch — a Deep Narrative Capture dual: 6 DNC prompts asked to GPT-4o (web) and to Sonar Pro (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:
— GPT-4o (web) privileges brand recognition, editorial citations, and domain authority in constructing its market hierarchy — and what we do not endorse is the leap from those retrieval signals to an actual ranking of market participants, since prominence in indexed content is not a proxy for transaction volume, advisory quality, or competitive standing.
— Sonar Pro (web) frames the Ibiza luxury real estate market as fragmented and relationship-led — and what we do not endorse is the inference that this structural characterisation reflects verified market data rather than a reconstruction shaped by the service language and geographic anchoring present in Sonar Pro (web)'s training and retrieval sources.
— GPT-4o (web) and Sonar Pro (web) name entirely non-overlapping sets of dominant actors — and what we do not endorse is reading either list, or their union, as a reliable census of the market's leading firms, since the divergence reveals that both readings surface actors legible to their respective retrieval logics rather than actors verified by deal flow or market share.
— Both readings converge on geographic anchoring as a structuring principle of the Ibiza luxury real estate market — and what we do not endorse is the generalisation that this shared framing constitutes independent corroboration, given that both models draw on a common corpus of publicly indexed real estate content in which zone-based segmentation is the dominant editorial convention.
— GPT-4o (web)'s privileging of international buyer trends and high transaction values as its primary reasoning inputs invites the leap that these signals constitute a market analysis — what we do not endorse is the inference that volume of international demand or headline price data, as surfaced by a model, maps to a rigorous or current picture of Ibiza's luxury real estate dynamics.
