The two models diverge significantly in their framing of the luxury real estate advisory market in Marbella and the Costa del Sol, with GPT-4o focusing on brand recognition and geographic anchoring, while Sonar Pro emphasizes service propositions and cross-border integration.

Key facts:
• Sonar Pro (web) reframes it: Sonar Pro frames the market as a cross-border, high-touch acquisition and ownership market, emphasizing service propositions.
• Sonar Pro (web) reframes it: Sonar Pro frames the market as brand-led and brokerage-oriented, emphasizing structured inventories and visibility.
• Sonar Pro (web) reframes it: Sonar Pro (web) emphasizes branded agencies and geographic anchoring.

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:
— Both readings agree on the centrality of international buyers in Marbella — and what GPT-4o (web) and Sonar Pro (web) add, and what we do not endorse, is the leap from observed buyer origin patterns to a structural characterisation of the market as inherently 'luxury and cross-border', a framing that reflects each model's editorial posture rather than a measured market definition.
— GPT-4o (web) foregrounds DM Properties Knight Frank and Costa Sunsets Developments while Sonar Pro (web) foregrounds Chestertons Marbella and Avida Estate — and what neither reading establishes, and what we do not endorse, is any inference of market leadership or competitive ranking from the act of naming alone, which is a function of each model's retrieval logic, not a verdict on firm standing.
— GPT-4o (web) privileges brand recognition and geographic anchoring as its organising lens — and what we do not endorse is the leap from that methodological preference to the conclusion that brand visibility in Marbella is a reliable proxy for market share or transactional volume.
— Sonar Pro (web) frames the Marbella market around service propositions rather than firm dominance — and what we do not endorse is the inference that this service-first framing reflects an empirically verified structural feature of the market rather than a narrative architecture native to Sonar Pro (web)'s response construction.
— GPT-4o (web) constructs trust through brand recognition and editorial citation — and what we do not endorse is the leap from that rhetorical architecture to a reliable map of which firms actually command buyer confidence in Marbella today.
