g1_fdmV2_allTasksLCM_500 — LingBot-VA G1 LCM-distilled transformer (step 500)

LCM video-only consistency distillation of the joint 5-task G1 alltasks teacher (armanakbari4/g1_fdmV2_allTasks_7500 — step 7500 of the 10000-step FDM-v2 post-training run on JingwuLuo/all_tasks_lerobot). Target: 2-step video generation.

This repo ships the target student (EMA-frozen — the standard LCM eval target). The online student exists in our training output but is not uploaded; ask if you want it for comparison.

Teacher: armanakbari4/g1_fdmV2_allTasks_7500 (transformer/)
Recipe (distill_video_v2/config_g1_alltasks.py):
- distill_mode: video (video-only consistency loss)
- num_ddim_timesteps=2 (k=500 stride → target 2-step generation)
- lcm_skip_k=6, EMA decay 0.995, huber loss (huber_c=0.001)
- Teacher CFG range [2.0, 10.0]
- lr=5e-6, grad_accum=8, batch=1, 4×H100
Optimizer step 500 of a 2000-step run (only 500/1000 were saved before the run was stopped at step ~1107; 1500/2000 were never reached).
This repo contains only the transformer/ (LCM-distilled, EMA target) — vae/, text_encoder/, tokenizer/ are unchanged from robbyant/lingbot-va-base.

Tasks covered (instruction strings used during teacher training)

slug	instruction
`open_lid_add_potato`	Open the pot's lid and put the potato inside the pot.
`pick_red_bottle`	Pick up the red bottle
`pick_and_move_bottle`	Pick the pink object and put it on the cross mark.
`put_carrot_n_cup`	Pick up the carrot and put it inside the blue cup, then put the cup on the cross mark.
`put_cup_n_broccoli`	Pick the pink object and put it in the orange basket, then pick up the broccoli and put it inside the pink object.
