Multi-Task DiT (Diffusion) — rm65b-sort-v0

LeRobot Multi-Task DiT policy trained on rm65b-sort-v0 (bimanual RM65 sort task, 3 cameras, 198 episodes / 91.5k frames @ 30 Hz, 1 task).

This repo holds three candidate deployment checkpoints from the same 100k-step run.

Training summary

• Architecture: Multi-Task DiT (multi_task_dit), CLIP ViT-B/16 vision (separate encoder per camera) + CLIP text encoder
• Objective: diffusion (DDPM scheduler, prediction_type=epsilon, 100 train timesteps, squaredcos_cap_v2 betas); DDIM-compatible — switch noise_scheduler_type to DDIM and set num_inference_steps=10 for fast eval
• Total steps: 100,000 | batch size 32 | Adam lr=2e-5, cosine decay, AMP, grad-clip 10
• Hardware: 1× L40S, ~17 h wall-clock
