Where each one falls short

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

AWS (Amazon Web Services)

  • Data transfer in is free and data transfer out is charged, which is the standard source of unexpected bills
  • Discounts require one or three year Savings Plan commitments rather than being automatic
  • Every service is priced separately, so a working architecture has no single published cost
  • The free tier is a promotional allowance rather than an ongoing free plan

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
