Flux 3 Image Klein: open weights, 5.6B parameters

People on reddit claim it's bad at generating images of people, apparently because they removed anything close to nsfw from the training set. Anyone already tried it?

Some examples of the Reddit posts/memes:

I gave Flux 3 Klein my typical human test that has never failed on newer image models and it did fail; in addition to lower quality, the fingers were definitely not the correct proportions.

Whether the cause is due to more safeguards against NSFW content is hard to confirm technically; it was more an intuition back in the Stable Diffusion XL days but I suspect modern training paradigms are better at correlative inference.

did you try with https://huggingface.co/black-forest-labs/flux-3-image-klein-... apparently the model is not going to work well unless this type of "prompt upsampler" is added

I did it in OpenRouter, which hits the direct BFL API.

It's editing capabilities have been really solid, but I've been disappointed with its ability to do finer text details (a niche use case for my own purposes). There's also a lot of reports of body horror outputs, but I haven't encountered any myself.

Still though, it's a lot like the porsche mission S vs the tesla roadster situation with the weights release. Moss Image dropped which looks far better at the moment, leading to a "why Flux?" question in the community.

I still think the edit capabilites are absolutely excellent, but for t2i I'd try out moss: https://huggingface.co/OpenMOSS-Team/MOSS-Image-Base/tree/ma...

I've been VERY impressed with Moss' design capabilites out of the box. Some samples:

https://image.non.io/5130501a-5c07-4635-82f5-fa64d60e8871.we...

IMO the taste is lacking, but it has some of the best text reproductions I've seen with their new VAE. Here's a type ramp example:
