A Professional's Review of FLUX: A Comprehensive Look

In this video, we explore Flux - the groundbreaking new image generation model from Black Forest Labs. As a fashion photographer and AI workflow expert, I break down:

What is Flux and how does it compare to previous models?
The different versions: Schnell, Dev, and Pro
My professional perspective on Flux's strengths and current limitations
Detailed installation guide for ComfyUI
Practical workflows and examples
License considerations for commercial use
Early impressions: Stunning results but some frustrations

How to Install Flux
Depending on the version you want to install, follow the following steps:

- Update ComfyUI by going to the ComfyUI folder, opening it in the Terminal, and typing "git pull"

Flux Dev (full version):

Schnell (full version):

Schnell or Dev, Quantized version:
- Download the model and place it in the ComfyUI/models/checkpoints folder
- You don't need to download and load the vae and clip models for quantized versions.

LoRAs:

ControlNet:
- switch ComfyUI branch by opening the ComfyUI folder in the Terminal and typing "git checkout xlabs_flux_controlnet"

Thanks for making tutorials that are not just the Bog standard “do this, do that, don’t explain why”
I love that you give us some perspective here in terms of the full view of the genAI landscape .

[houseofcontent]

This is an awesome review! I love that you're putting all the aspects in perspective. Thanks for sharing your honest opinion.

[MIkenpv]

I really like your perspective and teaching style! Thank you for making these videos!
As a newbie in diffusion model pipelines, I sometimes get lost in terminology in terms of what things do on practice. It would be really valuable to have high-level overview of different pipeline parts: checkpoints, encoders, loras, control-nets, IP adapters, VAE, CLIP, Samplers etc and most importantly what effect they have on the final result

[pixelcounter]

Thank you very much for sharing your information about the new model! From my point of view there is no need to hurry, because you already see some fast developments in improving the schnell and dev-versions .

[jovanniagara]

wow you're amazing, i'll use it for my bussiness

[ViralManiaElRey]

I thought the girl in the thumbnail was going to be the youtuber talking, I was shocked to realize that it was actually the generated image. It was great for me, considering I'm really into this topic.

[FrostyDelights]

Thanks very good video very clear and precise instructions !

[ubemark]

Enjoyed your Flux review. It is clear that you have expert knowledge as to how all this works together in order to get a desired result. Have you considered creating a sort-of walk-through video of your workflows that identify the parts.. like the checkpoint you choose provides this.. this sort of node does this to the image.. you mention IPadapters and controllers and so on.. I am just a hobbyist and I have used much of this.. but its really just a lit of tinkering and getting lucky.. or not. If any such video, or even a text and graphics source, for this stuff exists on a basic level that would allow someone to knowingly put together workflows like yours while knowing what goes where and why... that would be very helpful.

Flux is excellent, and to think that it is a base model. it promises a lot. I hope Matteo will develop IPadapter soon. The only problem I see is sometimes not understanding the depth of field, the blurs are very exaggerated and the image does not look organic in some cases.

[DarioToledo]

I am, or better I was a fashion photographer 😂😂😂😂
As time passes by, I'm afraid the more and more of us WERE photographers here.

Discussed it on reddit as well, but I find that Flux still has that "MidJourney" smooth effect that makes it less suitable for images in production. still a great model though, waiting for more development, I think the best way to use it now is for fast iteration and then img2img with traditional SD techniques

As a professional user in February 2025, I’m struggling to make a choice of what to learn next. I am a seasoned CGI guy 20 years experience and looking into the future which is obviously genAI.

Just a bit confused because flux pro has the horrible command line interface., I tried schnell and it just seems super basic in terms of tools and the generations are worse. But then there is this commercial license problem with dev, which otherwise seems pretty great.

I want to use comfyUI and all the fancy tool notes that come with dev. I have a lot of experience with nuke so comfy just seems super ace. 👍

do you recommend I learn some SDXL next?
I don’t mind paying, but I want control and I think comfy gives us that? Want to start using genAI for client work and all the endless revisions that clients want.

I am getting: KSampler
This Controlnet needs a VAE but none was provided, please use a ControlNetApply node with a VAE input and connect it.

I have a VAE-dev installed. do I need a separate one for the ControlNet? thanks

[svenhinrichs]

i realised the lora realism really fucked up my controlnet workflow for my aim to do architectural stuff....

[RutzNumberbutAfk]

Hey! What GPU do you recommend? I want to run Flux locally but currently have a 1070 ti :/

[havemoney]

I find it more convenient to use Forge for FLUX

[kaymifranca]

I am an art director and I work on advertising campaigns. What would be the best AI to generate product images? Or reproduce an image in different ways? thanks

[laemon]

what's the prompt for 16:20? or maybe link to the source 🙏

[frustasistumbleguys]

Can we use Flux with IPAdapter? How about combining Flux Lora realism with sdxl model checkpoint?

[robadams]

I've had no problems with many different input sizes, I use 1280 a lot. Dev does poor initial generations txt 2 img at higer resolutions but it does img to img up to 3000 picels without issues.
