    Do not download if you have not read all the suggestions

    Because it is heavy and requires more stuff than SD.

    And we have new way to run Flux ez with 1 click: https://civarchive.com/models/628682/flux-1-checkpoint-easy-to-use

    Check out more detailed instructions here: https://maitruclam.com/flux-ai-la-gi/

    To summarize my experience with it:

    - This is the SFW model 😭😭😭

    - Really sticks to the prompt

    - Recognizes and displays text very well

    - Variety of content can be created without Lora or additional training

    - Cool cool cool!

    How to use:

    - Write a simple prompt like you don't know MidJourney or Stable Diffusion (bye bye a bunch of techniques, brackets, strange codes and negative prompts)

    - Just a simple description like: a young woman lying on a bed wearing a shirt with the words "touch me".

    Cons:

    - The model is super heavy! 24GB

    - It takes a long time to create but it's cool: 30s/ 1024x1024.

    - Should use VPS or if you are not afraid of burning your laptop (or if you are rich, it depends on you :) )

    Note:

    - If you have less than 30GB of storage and 12GB of vRam, you should probably consider using it.

    - If you download and it doesn't work, change .safetensors to .sft.

    - Currently it only works with Comfy UI, simple workflow here:

    - A1111 will probably update... maybe.

    Checklist before, during and after running Flux with tons of errors:

    Before:

    - Is your computer configuration strong enough?

    - Minimum 12GB vRam, Nvidia 3060 card or higher (this is from me, not their official information, because my laptop running Nvidia 3060 6GB vram is fine even though it goes up to 105 degrees C when running)

    - Minimum 30GB of space to store models, VAE and CLIP?

    - Do you choose dev (quality) or schnell (fast) to run?

    Also, you should check my tutorial to understand how to install and some things around: https://maitruclam.com/flux-ai-la-gi/

    While:

    - Make sure you have downloaded all the required files into UNET, VAE AND CLIP

    - Make sure you have upgraded ComfyUI to the latest version

    After:

    - On average, the reports show that the minimum time when running with schnell is 10s for 1 photo 1024x1024px.

    - For weak devices, the time for each 1024x1024 photo is 2p - 45p (wtf this guy is really patient when waiting for 45p :))

    Free GPU

    - If you have unique workflows to process photos such as: creating a series of different result prompts, can process skin, color, change style,... Contact me and I am ready to share my VPS to discuss more in: https://discord.gg/PYefENGNRY

    My setting VPS:

    - I am using VPS on AWS.

    - VPS g5.4xlarge (GPU A10 24GB vRam)

    - 800GB of storage

    - If you want to share and use VPS, you can contact me via the comment, Facebook fb.com/maitruclam4real or email: [email protected].

    - I DO NOT SHARE FREE VPS, but will exchange with appropriate value (other software, services, knowledge of using VPS, creating videos on VPS Ubuntu, how to optimize AWS...) contact and exchange with each other about what you have and what I have so that both sides can happily share resources.

    FLUX.1 [dev] is a 12 billion parameter rectified flow transformer capable of generating images from text descriptions. For more information, please read our blog post.

    Key Features

    1. Cutting-edge output quality, second only to our state-of-the-art model FLUX.1 [pro].

    2. Competitive prompt following, matching the performance of closed source alternatives .

    3. Trained using guidance distillation, making FLUX.1 [dev] more efficient.

    4. Open weights to drive new scientific research, and empower artists to develop innovative workflows.

    5. Generated outputs can be used for personal, scientific, and commercial purposes as described in the flux-1-dev-non-commercial-license.

    Usage

    We provide a reference implementation of FLUX.1 [dev], as well as sampling code, in a dedicated github repository. Developers and creatives looking to build on top of FLUX.1 [dev] are encouraged to use this as a starting point.

    API Endpoints

    The FLUX.1 models are also available via API from the following sources

    1. bfl.ml (currently FLUX.1 [pro])

    2. replicate.com

    3. fal.ai

    ComfyUI

    FLUX.1 [dev] is also available in Comfy UI for local inference with a node-based workflow.

    I don't know if the dev team likes BlackPink, but if you prompt Asian or Korean, the face will look very similar to Jennie in BlackPink :)

    Sadly it's been kind of confirmed that Flux will NOT be finetuneable. Don't expect Pony Flux or any finetune really.

    Edit: I stand corrected! https://www.reddit.com/r/StableDiffusion/comments/1ekb9qj/simpletuner_v098_quantised_flux_training_in_40/

    Can someone point out the optimal parameters for the model? The main thing is Sampler. I have works like the author of the post, a little textured (noisy), but I see that here many people post beautiful works without noise....

    Anyone know how to get rid of the bokeh effect?Flux has no negative prompt and no amount of prompting for detail seems to work.

    Stability.ai had better get their act together. Imagine the Flux models finetuned and fully mature in a few months with dozens of user made checkpoints and merges.

    What is this "renowned" prompt adherence? im using dev model and its prompt adherence is hardly any better than SDXL...

    EDIT: I guess its good prompt adherence for 100 tokens. I was expecting more though, kept pushing 200-300 token prompts on it hoping it would wow me but it kept missing details. Guess I expected too much.

    FYI, I'm running Flux1 Dev on a RTX 4070 (12GB vram) with 64GB system memory, on a core i9-9900 and it generates 1024x1024 in about 3.5s/iteration. I've optimized my system some for SDXL but just to let you know that yes - you can run it without 24GB memory. (woohoo!)

    Someone posted here that FLUX won't be fine-tuneable. Not true!
    Here's how: https://github.com/bghira/SimpleTuner/blob/main/documentation/quickstart/FLUX.md

    It takes a LOT of vram (40GB+), so probably only cloud training which can't be a surprise to anyone.

    When I try to run it I am unable to select flux1-dev.stf, I tried to change it to safetensors but still no luck, any help is greatly appreciated!

    Well this thing definitely works but I am certainly doing something wrong. I'm going to try without the VAE I downloaded from Huggingface. Generation speed is great and this thing might be very useful once I work out the kinks.

    I got it working with negative prompts, I'll post it soon. Because I'm still testing if they really work. Because my goal was to get it working on A1111 but trying with ComfyUI default workflow it works :) instead of giving an error

    .... it's stupid that i download the Flux model from https://civitai.com/models/618692/flux?modelVersionId=691639 but yet, because in probably a attempt to scam buzz, you upload the model with the same hash.. it goes here instead.

    This mentions that this is the SFW version.
    Is there a NSFW version now? The wording seems to imply that there is a NSFW version.
