This looks great, very exciting. The paper is not a lot more detailed than the blog. The main Thing about the paper is they have an architecture that can include more expressive text encoders (t5-xxl here), they show this helps with complex scenes, and it seems clear they haven’t maxed out this stack in terms of training. So, expect sd3.1 to be better than this, and expect 4 to be able to work with video through adding even more front end encoding. Exciting!
