Pixaroma's episode 39 tests Black Forest Labs' new FLUX 3 Klein image model in ComfyUI with 19 free workflows:
- Text-to-image: photos/illustrations, a Z-Image realism pass, a prompt upsampler, text in images, box layouts, image-to-prompt-to-image
- Single-image editing: background swaps, box-restricted edits, changing text in images, restyling, season/time changes, restoring and colorizing old photos, character sheets, outpainting
- Multi-image combining: placing characters in scenes, outfit swaps, product logos, group photos, product ads
- Honest breakdown of weaknesses: hands, normal-size faces, the AI look, some fonts
Requires ComfyUI 0.41+; FLUX 3 files need free approval on Hugging Face. License allows commercial use under $5M yearly revenue. Each workflow has its own chapter.
