Official Fix (2025-07-28)

The official fix is being tested: https://github.com/nunchaku-tech/nunchaku/pull/557

✅ Patched LoRAs

Patched LoRAs	Original LoRAs
flux_kontext_deblur_nunchaku.safetensors	civitai or civitaiarchive
flux_kontext_face_detailer_nunchaku.safetensors	civitai or civitaiarchive

⚡ Usage

These patched LoRAs are compatible with ComfyUI-nunchaku.
Use the Nunchaku FLUX LoRA Loader node to load LoRA modules for SVDQuant FLUX models.

🛠️ Patch References

Some original FLUX LoRA files were missing required final_layer.adaLN weights needed by ComfyUI-nunchaku’s FLUX LoRA Loader.
This patch script automatically adds dummy adaLN tensors to make the LoRA compatible with SVDQuant FLUX models.

Script: patch_comfyui_nunchaku_lora.py

Based on:

Nunchaku Issue: ComfyUI-nunchaku #340

Node Type: NunchakuFluxLoraLoader
Exception Type: KeyError
Exception Message: 'lora_unet_final_layer_adaLN_modulation_1.lora_down.weight'
