[AINews] Reve 2 and Ideogram 4: Layouts in Imagegen

Reve 2.0 launches as the best 4K image model worldwide with precise layout generation enabling touchable images. Ideogram 4.0 becomes the best open image model using bounding boxes linked to region descriptions for structural understanding. Both models improve layout accuracy through explicit supervision and region labeling. The shift to layout-based prediction reduces image generation to a next token problem, cutting compute load significantly.
