FLUX 3 Image Klein: Comfy Workflow, HF Space and Prompt Upsampler Links
bfl_ai · x · 2026-10-17
BFL's follow-up post collects all FLUX 3 Image Klein resources: the ComfyUI workflow, Hugging Face Space, prompt upsampling tool, and the recommended system prompt published in the repo.
The model card details Klein as a 5.6B open-weights model (BF16/int8/NVFP4 weights) for text-to-image and editing, and stresses never using it without a prompt upsampler — raw short prompts produce generic output.
