FLUX.2-klein Image Edit 4B Base

Summary

Official FLUX.2-klein 4B base image-edit workflow from the Comfy workflow templates. Good for general editing tasks when you want the more flexible base model rather than the faster distilled path.

Developer notes

• This is one of the official workflow templates linked directly from the Comfy docs.
• The guide positions FLUX.2-klein as a unified text-and-edit model family for interactive editing, object changes, multi-reference work, and iterative edits.
• The workflow includes a documentation note listing the expected model filenames and storage locations.

Our notes

• Best use: trustworthy baseline for FLUX.2-klein editing without betting on a random community graph.
• This is probably the safer "quality over speed" 4B edit starting point.
• It is not labeled outpainting explicitly, but it is the same family of edit workflow you would use as an outpainting base after expanding the canvas / source image setup in Comfy.

Required custom nodes

• none beyond current official Comfy support for the FLUX.2-klein template nodes

Required model files

• models/diffusion_models/flux-2-klein-base-4b-fp8.safetensors
• models/text_encoders/qwen_3_4b.safetensors
• models/vae/full_encoder_small_decoder.safetensors

Notes

• If you mainly care about speed for outpainting experiments, use the 4B distilled entry first instead.
