The two models diverge significantly in their framing of trust attribution in the Luxury Real Estate Advisory market in London, with GPT-4o focusing on brand recognition and digital presence, while Sonar Pro emphasizes public legibility and inherited credibility.

Key facts:
• Sonar Pro (web) reframes it: Sonar Pro (web) emphasizes public legibility and inherited credibility in trust attribution.
• Sonar Pro (web) reframes it: Sonar Pro (web) emphasizes boutique discretion and private networks.
• Sonar Pro (web) reframes it: Sonar Pro (web) emphasizes relationship-led dynamics and market access.

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 GPT-4o (web) and Sonar Pro (web) converge on Knight Frank and Savills as high-trust actors — and what we do not endorse is the leap from model consensus to market verdict: agreement between two AI models trained on overlapping corpora is not independent corroboration, and carries none of the evidentiary weight of a sourced market ranking.
— GPT-4o (web) frames trust as a function of brand recognition and digital visibility, while Sonar Pro (web) grounds it in public legibility and inherited credibility — and what we do not endorse is the inference that either framing describes how luxury real estate clients actually assign trust, rather than how each model's training data has learned to narrate it.
— Sonar Pro (web) alone surfaces Sotheby's International Realty as a high-trust actor where GPT-4o (web) does not — and what we do not endorse is reading that asymmetry as a signal of relative market standing, since inclusion or omission here reflects retrieval and weighting patterns, not a comparative quality judgement.
— GPT-4o (web) frames London as a prestigious global hub while Sonar Pro (web) foregrounds boutique discretion and private networks — and what we do not endorse is the leap from either framing to a description of the market as it actually operates: both are editorial postures, not market surveys.
— Both GPT-4o (web) and Sonar Pro (web) name Knight Frank, and Sonar Pro (web) adds boutique firms including DJPS Luxe and Cherie & Co — what we do not endorse is the inference that named presence in a model's output reflects market standing, mandate volume, or competitive rank.
