+# 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.
