Notes

  • FLUX Schnell is the default and fastest model (~5s generation)
  • FLUX Pro v1.1 produces the highest quality but does NOT support guidance_scale or num_inference_steps
  • FLUX Dev is a good balance of speed and quality with full parameter control
  • FLUX Pro 1.1 Redux is for image-to-image transformations — requires image_url input
  • Recraft v3 is design-focused (logos, illustrations) — supports style and colors params
