Wizard

  • • Photo is HEIC-converted and resized to 1536px in the browser
  • • Looks and scenes come from the style_options table
  • • Generate fires three calls that share one runId

Gates and model choice

  • • Rate limit 12/h anonymous, 60/h signed in; one free anonymous run, then 402
  • • Prompt text passes injection and off-topic guardrails
  • • Subtle → flux-kontext-pro; polish and reimagine → flux-2-pro

Editor and operations

  • • Tweak, background, and resize reuse the same Flux models; uploaded scenes hit Stability remove-background first
  • • Captions use gpt-4o vision on the exported artboard
  • • Hourly cron checks BFL balance; every billable call logs USD cost to ai_usage
