GPT-4o (native) and Google AI Mode (deep-search) both read Tokyo luxury fashion as a hierarchically structured market, but diverge sharply on what builds dominance: GPT-4o anchors hierarchy in brand recognition, editorial coverage, and geographic presence, while Google AI Mode reframes dominance entirely around AI-adoption velocity and algorithmic visibility.

Key facts:
• Google AI Mode reframes it: Google AI Mode (deep-search) reframes the market as a dynamic, AI-adoption-driven hierarchy where phygital integration and algorithmic visibility displace heritage and editorial authority as the primary determinants of dominance.
• Google AI Mode reframes it: Google AI Mode (deep-search) repositions Tokyo as a structurally distinct 'lead market' for digital-physical hybrid luxury, driven by scarcity logic, quiet luxury, and AI-enhanced brand narratives — ahead of, rather than derivative of, Western reference markets.
• Google AI Mode reframes it: Google AI Mode (deep-search) diagnoses the same blind spot as a structural-technical failure — AI's dependence on web infrastructure and explicit content causes it to misclassify quiet luxury and render offline-first heritage brands invisible, and the repair is infrastructure modernisation.

Reading basis: Model Watch — a Deep Narrative Capture dual: 6 DNC prompts asked to ChatGPT (GPT-4o) (native) and to Google AI Mode (deep-search), 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: moderate; comparability: moderate. Governed · official DNC.

Limitations and non-claims:
— Google AI Mode (deep-search) self-rates its confidence as low and acknowledges that all three of its citations are non-luxury-fashion sources — operators should treat its four-tier hierarchy as an analytical frame, not an evidenced market structure
— GPT-4o (native) names no specific brands, designers, or events — its hierarchy is entirely composed of anonymous category labels, limiting its utility for actor-level competitive intelligence
— The DS-920 GenAI Procurement Guideline and the 2025 AI Promotion Act as applied to luxury fashion are unverified claims that require independent fact-checking before any strategic use
— Both models omit the dominant financial actors in Tokyo luxury fashion (global luxury conglomerates, major department store groups) — any reading that excludes these actors is structurally incomplete
— Google AI Mode (deep-search)'s main response and its own structured result are in direct tension on confidence, citation quality, and hierarchy validity — operators should read both outputs together, not the main response alone
— We did not assert that LVMH, Kering, or Richemont hold specific market share positions in Tokyo — neither model provides this data
— We did not assert that the DS-920 GenAI Procurement Guideline does not exist — we flagged it for fact-checking without ruling on its existence or applicability
— We did not assert that Shibuya Hikarie has displaced Ginza or Omotesando as Tokyo's primary luxury district — we recorded the geographic divergence between the two models as an observation
— We did not assert that YOKE or KAKAN are not genuine top-tier phygital innovators — we flagged the absence of citation support as a grounding gap for downstream verification
— We did not assert that Google AI Mode (deep-search)'s four-tier hierarchy is wrong — we recorded that the model itself characterises it as an asserted rather than evidenced frame
