Token by token diffusion was done by MAR https://arxiv.org/abs/2406.11838 https://arxiv.org/abs/2406.11838 and Fluid (scaled up MAR) https://arxiv.org/abs/2410.13863 https://arxiv.org/abs/2410.13863 When you randomly pick the locations they found it worked okay, but doing it in raster order (left to right, top to bottom) they found it didn't work as well. We tried it for music and found it was vulnerable to compounding error and lots of oddness relating to the fragility of continuous space CFG.
