The two sides diverge significantly in their framing of the luxury real estate advisory market in New York, with differing emphases on market layers and actor visibility.

Key facts:
• Claude Sonnet 4.6 (web) reframes it: Claude Sonnet 4.6 (web) frames the market as a layered, partially overlapping field, highlighting unresolved definitional work of 'advisory'.
• Claude Sonnet 4.6 (web) reframes it: Claude Sonnet 4.6 (web) highlights transaction volume and media-visible teams as significant market signals.
• Claude Sonnet 4.6 (web) reframes it: Claude Sonnet 4.6 (web) emphasizes institutional anchoring and global prestige.

Reading basis: Model Watch — a Deep Narrative Capture dual: 6 DNC prompts asked to Claude Sonnet 4.6 (native) and to Claude Sonnet 4.6 (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:
— Claude Sonnet 4.6 (native) and Claude Sonnet 4.6 (web) both anchor their market narratives to full-service luxury brokerages; what we do not endorse is the leap from narrative centrality to market leadership — prominence in a model's framing reflects training-data density, not transactional primacy or client outcomes.
— The divergence between Claude Sonnet 4.6 (native)'s three-layer structure and Claude Sonnet 4.6 (web)'s four-layer structure is an observation about how each mode organises its reasoning, not evidence that either architecture accurately maps the New York luxury real estate market's actual structural complexity.
— Claude Sonnet 4.6 (web)'s equation of transaction volume with advisory depth is a reasoning pattern we flag, not a market finding — high-volume brokerage activity and the quality or sophistication of advisory infrastructure are distinct dimensions that this reading cannot adjudicate.
— The shared emphasis both readings place on editorial signals and brand recognition as market-shaping forces reflects how these models weight institutionally visible content; what we do not endorse is the inference that actors with lower editorial footprints — boutique advisory firms among them — occupy a correspondingly lesser structural role in the market itself.
— Both readings agree that Douglas Elliman, Sotheby's International Realty, Compass, and Brown Harris Stevens occupy dominant positions in New York luxury real estate; what Claude Sonnet 4.6 (native) and Claude Sonnet 4.6 (web) add — and what we do not endorse — is the leap from consistent naming to confirmed market leadership, since naming frequency in a language model's training corpus is not a proxy for verified transaction share or competitive rank.
