How Sellie picks models
Identify item · photos → details
claude-opus-5.5 → claude-sonnet-5.5 → claude-opus-5
Reading tags right sets the price, and it runs once per item, so it gets the strongest vision model.
Providers tried per model: anthropic, vertex, bedrock
Grade photos · photos → scores
claude-haiku-5.5 → claude-sonnet-5.5
A simple good/fixable/retake call; Haiku is ~40× cheaper than Opus and the fastest.
Providers tried per model: anthropic, vertex, bedrock
Write listings · text → text
claude-sonnet-5.5 → claude-haiku-5.5 → claude-opus-5.5
Good marketplace copy at half Opus's price and faster; nothing here needs top-tier reasoning.
Providers tried per model: anthropic, vertex, bedrock
Honesty check · photos → verdict
claude-sonnet-5.5 → claude-opus-5.5
Runs on every edited image and must catch changed items reliably; Sonnet balances both.
Providers tried per model: anthropic, vertex, bedrock
Item outline · photo → mask
gemini-nano-banana-2.1 → gemini-3.1-flash-image → gemini-2.5-flash-image
Output is just black and white, so the fastest, cheapest image model wins (~$0.03).
Providers tried per model: google, vertex
AI model photo · photos → photo
gemini-3-pro-image → gemini-nano-banana-2.1 → gemini-3.1-flash-image
Buyers see it, so it gets the most faithful image model (~$0.13); cheaper backups are still gated by the honesty check.
