    Error(s) in loading state_dict for Flux: size mismatch for img_in.weight: copying a param with shape torch.Size([3072, 384]) from checkpoint, the shape in current model is torch.Size([3072, 64]).

    EDIT: Update your comfyui people...

    I'm using Forge UI and getting a similar error (VAE state dict gives weight dimensions as 3072x384, but the number of in channels when the model is initialized is 64).

    Updated and same Error.

    can you create GGUF 8 ?

    Is GGUF better then just the FP8?

    JKrekelJan 26, 2025· 2 reactions

    @runebloodstone Yes, generations with GGUF 8 are almost identical to FP16, whereas FP8 is less accurate.

    Thank you for doing this. But in my case the model sometimes doesn't follow the prompt at all somehow. Is it because it's FP8?

    willhsmitNov 23, 2024· 1 reaction

    tested this against SporkySporkness/FLUX.1-Fill-dev-GGUF quants and the differences are very subtle with the same seed. I would guess any flaws are in the original model (or maybe the frontend you're using).

    There is less prompt adhernece cause it loses precison through quantisation

    can you please post the workflow for using this?

    I tried using the flux fill template but I am seeing grainy pixels.

    using the following models

    clip_name1: clip_I.safetensors

    clip_name2: 15xxl_fp8_e4m3fn.safetensors

    unet name: fluxFillFP8_v10.safetensors

    weight_dtype: fp8.e4m3fn

    use T5XXLfp16 and update your comfy. Default fluxfill wf should work then

    superdumbkittenNov 23, 2024· 1 reaction

    same here, I already update to the newest comfy, but I still get pixelated image, don't know why

    superuser111Nov 23, 2024· 1 reaction

    I have the same thing. The image gets very muddy, consisting of dirty pixel mush. I used the standard fill workflow.

    DainzhNov 23, 2024· 1 reaction

    Can confirm that the problem is also present on the GGUF models (2 of the made gguf models have this).

    superuser111Nov 23, 2024· 1 reaction

    @Dainzh That's right, I was just using gguf. I took Q4 and Q5 from here: https://huggingface.co/SporkySporkness/FLUX.1-Fill-dev-GGUF and they both have this problem. Is there a normal gguf without this problem?

    DainzhNov 23, 2024· 2 reactions

    Seems like not a gguf problem, or fp8 problem or any other problem model related, because I've just tested with regular fill dev mode which is 22 gb and it has the same problem. Something tells me this is due to the ComfyUI problem itself, and I don't really know what might be causing it.

    @superuser111 Are you using any custom nodes by chance?

    superuser111Nov 23, 2024· 1 reaction

    @Dainzh Very sad, hope the problem is resolved soon.

    superuser111Nov 23, 2024· 2 reactions

    @Dainzh I used the standard workflow taken from here https://civitai.com/models/970162?modelVersionId=1088649, only replaced flux model node with gguf

    Thanks OP it worked! For those who are struggling try using the image provided by OP for testing.
    Also found this guide below which gives details on expected parameter values.

    For thosee who still struggling for the noisy image, adjust the cfg to 7or8, the cfg is 1 in detault workflow.

    Does anyone have a workflow for using this model's outpainting feature?

    @1girls No thanks, it's like using a push-button phone instead of a smartphone. Yes, it works too, but it has been outdated.

    @13_february wrong concept.. flux is overhyped. technically you dont need it if you are good with the tools in hand

    ApexArtist1Dec 2, 2024· 1 reaction

    @junkyard001 loads of workflow nodes from third party repo is trash.. more nodes doesnt mean you are good at it.. i dont like youtubers workflows i make my own

    13_februaryDec 3, 2024· 3 reactions

    @1girls Even so, I didn't ask for an outpaint workflow based on 1.5 model🤷 It cannot work out small details efficiently. Yes, it can expand an image with a simple background, but highly detailed images are not it's strong suit. Flux didn't get its overhype for nothing. Its main feature is high consistency in details. With it, you don't get a hodgepodge in details like in the 1.5 and SDXL models when you you work on high-resolution art illustrations.

    Does not work on Forge? "RuntimeError: mat1 and mat2 shapes cannot be multiplied"

    Zephyrus_ZealzNov 19, 2025

    Getting the same issue. Can't use ComfyUI as it shows the below error. I wonder if any tried this with WebForge NEO.
