## 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
