FLUX.1 Kontext [Dev] – Open Weights for Image Editing

Here's hoping the distilled [Dev] model can hold up reasonably well against the larger pro/max models which in a lot of ways can completely replace the relatively old-school inpainting techniques of Stable Diffusion.
Some before/after experiments with editing images using Kontext:

The new non-commercial license is a bit of a doozy: https://huggingface.co/black-forest-labs/FLUX.1-Kontext-dev/...

If I’m understanding this correctly, you can’t run this in a commercial setting, even if you’re not creating a derivative but simply generating outputs?

I believe you can buy licensing? But def not the same as 'Open Weights..'

"Weights available" perhaps

The same people that claim using all of humanities creation is fair use want you to pay for a bunch of MatMul inputs that are unrecognizable to anyone after quantizing them yourself.

Stupid question, whats to stop someone from quantizing it, shit even just barely finetuning it for 1 step and calling it something different, no ones actually checking WTF these models are based on when they're released, especially for the source models, especially if the release is not around the same time of release as the base, i'm 99% sure someone could fine tune SD3.5 a bit and release it today as Frizz 1.0 and people would just take it as a new model using the same layer structure as SD3.5 lol

Neat, I plan to check this out.
I really want an AI to jam with on a canvas rather than to just have it generate the final results.
I have been hoping someone would pick up on the time series forecasting innovations in the LLM space, combine them with data from e.g. the Google quick draw dataset, and turn that into a real-time “painting partner” experience, kind of like chatting with an LLM through brush strokes.

Using the kontext models in Fal.ai shows you a nice slider of the before and after edits and has a button that lets you set the edited image as the new source so you can continue to make changes.
Now that BFL has released a dev model, I'd love to see a Kontext plugin for Krita given that it already has one for Stable Diffusion though!

this intent in licenses might lowkey prescreens who even gets to build. this creates a soft perimeter = technically open, operationally narrow. it's shaping who can even try, plus cuts out misuse but also cuts out maybe-use. over time, that subtly redefines what counts as valid experimentation

I was at a hackathon with this thing last weekend in SF at bfl. It's a pretty good system.

What sorts of things were built with it?

This is awesome, and kudos to BFL for releasing the weights. The financial sustainability of open-source is hard to get right, and giving academics this model for free while charging a reasonable licensing fee for startups is something I think makes sense if it allows BFL and others to continue releasing open-weight models.
