    How do you run this model in ComfyUI when in Nunchaku repo are missing files like transformer_blocks.safetensors, unquantized_layers.safetensors and all the .json files which are required by Nunchaku FLUX DiT Loader?

    Do you have run (Flux dev nunchaku version) before ?
    If not, you have to install nunchaku to your comfyui

    If yes, you have run Flux dev nunchaku version on your comfyui.
    you have to check a u downloaded this 2 safetensors

    6.3GB\\ ComfyUI\models\diffusion_models\svdq-int4_r32-flux.1-krea-dev.safetensors

    4.8GB\\ ComfyUI\models\text_encoders\t5xxl_fp8_e4m3fn_scaled.safetensors

    if yes, then you may need to install missing node at your comfyui manager
    I wan run these on WIn11-(comfyui desktop app), easy to use and manage

    BlackLabe188 My problem are all the missing LoRAs in the workflow. (Style)aidmaMJv7-FLUX-v0.1.safetensors, (Detail)Flux_Detailer_v3.safetensors, (Detail)FluxDFaeTasticDetails.safetensors, (Light)AestheticDetails_V1.safetensors

    vladulidloAug 4, 2025

    Thank you. I have run Nunchaku before but only with "folder models". I didn't know Nunchaku started to support single safetensor files, this is new.

    When using your models and your workflow in latest comfyui (desktop github install ) i always receive

    Lora Loader errors

    https://imgur.com/a/ctol9zg

    and this although everything mentioned in your models and workflow is at its place and installed including nunchaku nodes from the manager.

    I tried to switch nightly or latest but it makes no difference .

    Also set comfy it to "weak" level with same issue.

    I am using Win11-Comfyui-desktop.
    I think you are unsuccessful install nunchaku plugs-in into comfyui, it is not just install a node.

    another way to fix
    1) run comfyui desktop app
    2) click [Manager] to open comfyui manager
    3) click [Install via Git URL] and paste https://github.com/nunchaku-tech/ComfyUI-nunchaku
    4) should be wait 2min, when done restart comfyui may continue install, may need restart again.

    metulski Locate the config.ini file of ComfyUI Manager. C:\ ?ComfyUI/user/default/ComfyUI-Manager/config.ini
    security_level = normal ---> security_level = weak

    sound like you a New on Workflow ?
    you can <disable all Lora node> and just run the base-model & text_encoder to create photo.
    Select the nodes you want to ignore and press “CTRL + B” for bypass.

    metulskiAug 4, 2025

    BlackLabe188 Hi. Thanks or the Info. I know that I can disable them, but how an I surposed to know that these are not needed for the workflow?

    Hi. This workflow need s a hidreamCLIPDistilledFor_distilledCLIP text encoder. Do you have a link for that file?

    metulskiAug 3, 2025

    I is like a puzzle. I found a hint to the text encoder on the Flux krea dev (nunchaku svdq-fp4) Base-Model page. It says text_encoders 2 : HiDream CLIP - Distilled for Flux (Download). However the link goes to a page with two versions of a file, and non has the name from the workflow. The names are "longCLIPDistilledNew_distilledCLIPG" and "longCLIPDistilledNew_distilledCLIPL"

    No need to copy all my lora / text_encoder
    find your way to try any possible 😎

    metulskiAug 4, 2025

    BlackLabe188 I did use the noral clip_l encoder and it works just fine. But it wound be great it you would only upload workflows with stock encoders or clead instructions on where to get these files.

    mystifying you can use any Flux Dev text_encoders / e.g: clip_I ,
    I use (hidreamCLIP) because it's easier to get high quality pictures.
    hidreamCLIPDistilledFor_distilledCLIP (471.71MB), I always rename the files

    1) to Gen. a photo in 20sec, you have to use nunchaku-base-model _file.name: svdq-**4_r32-flux.1-krea-dev.safetensors
    2) comfyui install nunchaku node / plug-in
    3) use my workflow
