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.

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.
