# FLUX.2-klein Multi-Reference 3-Image Workflow

## Summary

Same-day Hugging Face workflow pack for `FLUX.2-klein 9B` with a practical multi-reference graph. This is the kind of reference-control workflow worth watching because it aims at composition and identity control, not just a style demo.

## Model Family

- `flux2klein`

## Status

- `imported-only`

## Source

- Model page: <https://huggingface.co/geceff/Flux2Klein9B-comfyui>
- Workflow file: <https://huggingface.co/geceff/Flux2Klein9B-comfyui/raw/main/workflow/Flux2image-reference-api-3image.json>
- Original publisher: `geceff`
- Date imported: `2026-08-15`

## Developer notes

- The source repo ships a full `FLUX.2-klein` ecosystem plus multiple workflow JSONs and packaged weights.
- This graph uses three reference images and a `FluxKontextMultiReferenceLatentMethod` node, so it is more focused on practical reference handling than a plain text-to-image template.

## Our notes

- Worth testing if you want a more functional FLUX.2-klein reference workflow than the standard edit templates.
- The source pack looks broad and somewhat opinionated, so treat it as a workflow donor rather than a clean official baseline.
- On an `RTX 3070 8 GB`, expect this to be heavy. It is more of a benchmark or tuned workflow than a comfy default.

## Required custom nodes

- `FluxKontextMultiReferenceLatentMethod` or the Comfy/Flux extension that provides it
- Current Comfy `FLUX.2-klein` template nodes such as `ResolutionSelector`, `ReferenceLatent`, `ScheduledCFGGuidance`, `ModelSamplingAuraFlow`, `CLIPVisionLoader`, and `unCLIPConditioning`

## Required model files

- `Flux2Klein_9B_v4BaseFp8.safetensors`
- `Flux2Klein_base-bf16_master_v4.safetensors`
- `fulx2vbase-lora-master.safetensors`
- `flux-2-klein-9b_extracted_lora_rank_128-fp32.safetensors`
- `bfs_head_v1_flux-klein_9b_step3500_rank128.safetensors`
- `qwen-3-8b-flux-klein.safetensors`
- `flux.2vae-bf16.safetensors`
- `clip_vision_g.safetensors`

## Notes

- The workflow file still uses `example.png` placeholders for the image inputs.
- This is a promising reference-control donor, not a proven replacement for the current `FLUX.2-klein` edit masters.
