“Doesn't allow me to edit any real world photos with humans involved. So it is pretty useless at this point.”
“Lol! Out of 20 images I could only get one Image to show due to filter. Uploaded a girl in a tank top simple command add armpit hair and flagged. Not very useful for any real editing. Even expanding an image with a girl walking thru a graveyard was censored.”

“the point about avoiding "laziness" of multi-referencing models in favor of first-frame image-to-video for precise camera control is a genuinely useful technique. been doing similar first-frame control with models on omnely, cheaper per generation which matters when you're being this deliberate about each shot”
“When is the token consumption for these image gen models going to go down? I burned through 300,000 tokens and now I'm stuck with just 12,000 💀. 'Nano Banana Pro' was so good I ended up using almost 90 percent of my tokens. Now I can't even try 'Flux 2' because I need the rest for voice generation.”
“BFL have a strange approach to things tbh - all their models are built for consumer hardware, yet only the weakest have licenses which really allow them to get used properly. Their higher end models like Flux2.FLEX remain completely unavailable, even though I’d be very surprised if it couldn’t run on a 5090 at Q8. Maybe Q4 at a hard push. It’s in an odd spot where it’d be godlike in the open source realm, but I can’t imagine it gets any attention at all at the frontier level since by comparison ”
“FLUX.2 [dev] generated pictures are not allowed to be used commercially =( I have read that the soon-to-be-released FLUX.2 Klein will allow it though.”

“Not a lot here I like. Mostly because there's a reason why you don't train audio/video/image models as one model. If you do, it becomes harder and harder to fit on consumer hardware. And maybe they don't care about that, but it's weird to tout their success with Flux 1 as being for consumer hardware. The other thing is that robotics have not made the same strides that AI has for one very important reason: physical problems are still present. The issue with robotics is not simply a matter of buil”
“Many thanks for another awesome video. Tried Flux2 at BFL Playground, looks great, the best result came from turning off prompt enhancement and using JSON. Then it's possible to add "log gamma, flat picture profile" as a line and while it's not perfect, you get some extra information in the midrange.”

Questions
Frequently asked
What is FLUX?
FLUX is an AI image generation platform by Black Forest Labs that creates professional-quality images from text prompts. It offers multiple model variants ranging from ultra-compact 4B parameters to full-scale versions, accessible via API or deployable as open weights. The platform supports images up to 4 megapixels in resolution with flexible pay-per-megapixel pricing instead of traditional subscriptions.
How much does FLUX cost?
FLUX uses pay-per-megapixel pricing with no subscriptions or seat fees. The highest quality FLUX.2 [max] costs $0.07 for the first megapixel and $0.03 for additional ones, while the ultra-compact FLUX.2 [klein] 4B model charges $0.014 and $0.001 respectively. There are also pro, 9B, and flex pricing tiers with different rates based on quality and speed needs.
What's the difference between FLUX model variants?
FLUX offers multiple models optimized for different needs: FLUX.2 [max] provides the highest visual fidelity, FLUX.2 [pro] balances quality and speed, while FLUX.2 [klein] comes in 9B and 4B parameter versions for high throughput applications. The smaller models generate images faster and cost less, while larger models produce higher quality results.
Can I deploy FLUX on my own infrastructure?
Yes, FLUX offers open weights licensing that allows you to deploy models on your own infrastructure. The Builder tier provides 10K images monthly for smaller teams, scaling up to Enterprise with unlimited access. This gives you full control over deployment while maintaining commercial licensing rights.
What image editing features does FLUX include?
FLUX includes FLUX Outpainting for expanding images beyond their original boundaries and FLUX Eraser for selective content removal. The platform also supports image-to-image generation with reference images for style matching, and allows fine-tuning with LoRA customization for specific use cases.
What's the maximum image resolution FLUX can generate?
FLUX can generate images up to 4 megapixels in resolution. The pay-per-megapixel pricing model means you only pay for the resolution you actually need, making it cost-effective for both small preview images and high-resolution professional outputs.
Does FLUX offer enterprise-grade security and compliance?
Yes, FLUX provides enterprise features including SOC 2 Type II and ISO 27001 compliance. The platform integrates through a REST API with comprehensive documentation and offers commercial licensing rights, making it suitable for business and production environments.
What's coming in FLUX 3?
The upcoming FLUX 3 promises multimodal capabilities that will span image, video, and audio generation within a single model. This represents a significant expansion beyond the current image-focused FLUX.2 family, though specific release details aren't provided.
