You're right that pricing from raw pixels is noisy! that’s why I included the isolated flatlay (S4 - No human, No outfit, only jewelry itself) as a baseline control!
I wasn't testing if models get absolute ground-truth prices correct, but how relative valuations shift when the physical item stays identical and only the attire changes.
A few interesting things we saw with the flat-lay baseline:
- Baseline Anchoring: On a plain background without a person, model estimates clustered much closer together (median ~$25–$35).
- Inflation vs. Deflation: Comparing outfits to the flat-lay revealed two opposite behaviors. Claude’s halo is formal inflation (formal gear pushes price above baseline), while Kimi’s is casual deflation (yard attire drags price below baseline).
- Fabricated Proof: Instead of expressing uncertainty, models invented visual claims under formal framing—frequently describing base metal as "gold vermeil" or "solid gold" to justify the high estimate.
