  • 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

Stampli

  • Pricing is by quote only: the pricing page publishes no rate, no minimum and no cost driver, offering only a Request a Quote form
  • Payments and card products are sold alongside the core AP automation rather than being separately priced on the public site
