GPT-4o (native) and Claude Sonnet 4.6 diverge in their framing of the market's structural layers and actor visibility.

Key facts:
• Claude Sonnet 4.6 (native) reframes it: Claude Sonnet 4.6 frames the market as an internationally oriented property advisory ecosystem.
• Claude Sonnet 4.6 (native) reframes it: Claude Sonnet 4.6 highlights lifestyle signals and brokerage dominance.
• Claude Sonnet 4.6 (native) reframes it: Claude Sonnet 4.6 highlights digital visibility and structured data signals.

Reading basis: Model Watch — a Deep Narrative Capture dual: 5 DNC prompts asked to GPT-4o (native) and to Claude Sonnet 4.6 (native), 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 (native) and Claude Sonnet 4.6 (native) each produce a coherent framing of the Ibiza luxury real estate market — 'niche high-value segment' versus 'internationally oriented advisory ecosystem' — and what we do not endorse is the leap from either framing to a structural description of the market itself; these are narrative architectures, not market surveys.
— GPT-4o (native) privileges geographic anchoring and service specialisation while Claude Sonnet 4.6 privileges editorial citation and content production, and what we do not endorse is the inference that either reasoning method surfaces more complete or more accurate actor coverage — each method selects for a different visibility logic, not a fuller picture.
— The divergence between GPT-4o (native) and Claude Sonnet 4.6 on structural layers and actor visibility is a divergence in model construction, and what we do not endorse is the reading of that gap as evidence that one model's map of the Ibiza market is closer to ground truth than the other's.
— The divergence between GPT-4o (native) and Claude Sonnet 4.6 (native) in framing market maturity — geographic anchoring versus lifestyle signalling — reflects each model's internal weighting of available training signals, not a measured difference in advisory depth between the two approaches as they exist in the Ibiza market.
— Both GPT-4o (native) and Claude Sonnet 4.6 (native) name Engel & Völkers as a key actor; what we do not endorse is the leap from consistent model citation to a verified ranking of brokerage dominance — prominence in training data and market leadership are not the same credential.
