Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

Refact

  • Requires configuration for optimal performance
  • On-premise deployment adds operational complexity
  • Free tier limited by daily agent request quota
  • Coin system adds complexity to cost calculation

Stable Diffusion

  • Generated images have lower resolution and quality at non-standard dimensions
  • Struggles with complex multi-object prompts and text generation
  • Poor rendering of human hands, limbs, and faces due to training data limitations
  • Trained primarily on English-language descriptions, reinforcing Western cultural bias
  • Requires significant GPU computational resources for local deployment
