# ART ATLAS — external LLM handoff, version 3 Purpose: The user's ChatGPT/Claude/other LLM interprets their free-form request, searches this catalog, compares real candidates, and makes the final selection. The website does NOT run a language model or decide what "American-looking" means. Collection: 20000 artworks. Saved real-image CLIP analysis: 19986. Unavailable analysis: 14. Model: openai/clip-vit-base-patch32. URL RESTRICTIONS AND LINK NAVIGATION Some LLM fetch tools only open URLs already seen in fetched pages. Do not repeatedly try invented URLs or assume altered query parameters were used. Compare the returned criteria to your intended criteria. Start at this published link: https://contemporary-art-20000.pages.dev/ai/build/ Follow links to choose category and add concepts; each next page offers exact links to set strength and weight, then a link to fetch 12 candidates. Use these links, not a fabricated URL, when your fetch tool requires prior-seen URLs. This navigation works for arbitrary combinations of the supported concepts; it is not a fixed set of example searches. Path-based result URLs identify each condition set without relying on query-string handling. The returned Search URL and criteria identify the actual request. WORKFLOW 1. Read the user's intent. Preserve negation, degree, subject and artwork type. For ambiguous cultural words explain your chosen interpretation, or ask if it materially changes the result. Do not equate an aesthetic with artist nationality. 2. Translate the interpretation into 1–12 concept IDs listed below. Choose a desired strength from 0 to 100: strong=95, mild=62, avoid=5. These are relative positions in this collection, not probabilities. Optional importance weight: >0 to 5, default1. 3. Fetch an actual candidate search URL. If your tool rejects generated URLs, use the linked builder above. Do NOT send "American-looking" directly as q and stop at the site's keyword-parser error. Instead YOU, the caller LLM, create traits. https://contemporary-art-20000.pages.dev/ai/search?traits=ID:STRENGTH,ID:STRENGTH&category=painting&limit=12 Optional weight: traits=graphic:95:2,vivid:90:1 HTML is default. Append &format=md for concise text, &format=json for JSON. category: painting, drawing, print, photography, sculpture, other; omit to include all types. "絵画" means painting. Discuss whether prints/drawings should also be included if relevant. limit:1–24. Usually fetch 12 candidates before choosing 3. Different artists by default; use diverse=false if the user wants one artist. 4. Read the returned candidates, condition values, media, and artwork URLs. When possible open images or artwork pages to verify visual fit. If poor, adjust your interpretation/traits and search again. You may combine candidates from multiple searches, deduplicating IDs. 5. Choose the requested number, explaining your interpretation and each choice. Cite the real /artworks/{id} URL. Distinguish saved AI impressions from facts and your own visual inspection. Do not claim you viewed all 20000 images. EXAMPLE, NOT A FIXED MEANING User: "アメリカっぽい絵を3枚" Possible interpretation A: American-pop visual energy -> graphic:95,vivid:90,cartoon:85, category=painting. Search: https://contemporary-art-20000.pages.dev/ai/search?traits=graphic:95,vivid:90,cartoon:85&category=painting&limit=12 Possible interpretation B: nostalgic wide-open landscape -> landscape:95,airy:90,nostalgic:85. It does not guarantee a US location, desert, highway, or western genre. Possible interpretation C: urban graphic atmosphere -> city:95,graphic:85,energetic:85. It does not guarantee New York. Choose or clarify among these interpretations. "American artist" is a factual nationality constraint: this dataset has no verified nationality field, so it cannot be satisfied by appearance scores. CAPABILITIES / LIMITS - Saved features cover 97 concepts, not every possible narrative, object, art movement, country, or composition. - No API key, account, or site-side LLM required for these read-only search URLs. - If the URL cannot be fetched, report the access failure. Do not invent a selection or pretend the whole catalog was searched. The user's browser can open an LLM-generated search URL; they can paste its text result back. The main website can also copy candidate information. - Artist, title, medium, source and category come from the existing gallery catalog; inferred impressions are explicitly separate. Category is a metadata classification, not an art-historical guarantee.
