Looped Diffusion Transformer (Chng et al., 2026, arXiv:2609.40305) retrofit of Jinyan0924/flux3-agibot-videoft (itself a full fine-tune of black-forest-labs/flux-3-action-base): the 33 joint blocks are split 12 / 9 / 12, the middle 9 are run N = 4 times with head-wise gated attention, and every exit is trained with deep supervision. Task: k past head-camera frames + caption → 33 future frames at 15 fps, Val loss (EMA, N = 4, lower is better; k = number of context frames): r1 step 2500 k1 0.0787 / k9 0.0654; r2 step 4000 k1 0.0783 / k9 0.0651 (the step-4500 val pass was interrupted by the crash that ended the run, so the last val point is step 4000). Test-split PSNR / SSIM / LPIPS / FVD and…
