Multimodal is the only image generation modality that matters going forward. Flux, HiDream, Stable Diffusion, and the like are going to be relegated to the past once multimodal becomes more common. Text-to-image sucks, and image-to-image with all the ControlNets and Comfy nodes is cumbersome in comparison to true multimodal instructiveness.
I hope that we get an open weights multimodal image gen model. I'm slightly concerned that if these things take tens to hundreds of millions of dollars to train, that only Google and OpenAI will provide them.
That said, the one weakness in multimodal models is that they don't let you structure the outputs yet. Multimodal + ControlNets would fix that, and that would be like literally painting with the mind.
The future, when these models are deeply refined and perfected, is going to be wild.
