An imo fascinating wrinkle that the article doesn't get into, Black Forest's main use case for their Flux models is "analytical" (modifying the user's pre-existing material, storyboards in this case) rather than "generative" (modifying stored material from the model's training corpus). In my experience with these tools so far, the analytical approach is more filmmaker-friendly, with image models fitting comfortably into well-established rendering and compositing roles. Meanwhile my current guess is that creative applications of the generative approach are going to end up looking a lot more like gamedev than filmmaking.
