# FLUX.2-klein Image Edit 9B Base

## Summary

Official `FLUX.2-klein` `9B base` image-edit workflow from Comfy's template set. Heavier than the 4B options, but likely the better choice if you want maximum flexibility from the official `klein` edit stack.

## Developer notes

- This is the official `9B base` edit template from Comfy's published workflow list.
- The docs point users to the BFL repo for acceptance and download of the 9B diffusion weights.

## Our notes

- Use this when the `4B` variants are good enough to prove the workflow direction, but you want a stronger ceiling.
- More of a second-step workflow than a first try, especially if your box is tight on VRAM.
- Also a plausible outpainting path once the lighter template is validated.

## 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-9b-fp8.safetensors`
- `models/text_encoders/qwen_3_8b_fp8mixed.safetensors`
- `models/vae/flux2-vae.safetensors`

## Notes

- Better treated as a quality-upgrade path, not the first one to debug.
