MVWM LoRA checkpoints

Research checkpoints from MVWM, a multi-person, multi-view video world model project. Every file is a LoRA (plus a few small extra modules) trained on top of the Ref2VA variant of MiniMaxAI/MiniMax-H3. The weights cannot be used on their own: you need the base model and the matching training/inference code, which is not public. The safetensors headers carry no metadata beyond {"format": "pt"}.

Layout

<run>/step-N.safetensors is the checkpoint after N loop steps. In the dual-DiT runs (ckpt_gather_*), 2 loop steps make one optimizer update.

Run	Recommended step	What it is
ckpt_gather_s11	1200 (also 800)	Current main line. Two views run as two sequences. In every self-attention layer, each view's keys and values also include up to K=128 tokens per frame gathered from the other view, under one softmax with no new parameters (gather_config.json). Not fully trained.
ckpt_gather_s12	1200	Same as s11, but with K=64.
ckpt_gather_s14	400 (also 600)	s11 plus Plücker ray-map camera conditioning. Ties s11 at step 400 and is about 1 dB worse at step 600.
ckpt_v1_kf3_cont	1250 (also 1812)	Stage-1 final recipe: both views stacked into one video, full attention, soft first-frame anchoring, gray-background box proxy, time-aligned proxy, rank 32. Step 1250 is the final stage-1 checkpoint (2250 steps in total).
ckpt_v1_kf3	—	Run that ckpt_v1_kf3_cont continues from.
ckpt_v2_ha, ckpt_v2b_ha	1812 (v2b)	Stage-1 variant: hard anchoring, rank 128. Did not beat v1.
ckpt_v3b / ckpt_v3b_shared	750 / 1002	Stage-2 identity-colored proxy, without / with a shared-entity cross-view attention mask.
ckpt_cwm_v3c, ckpt_cwm_v3c_eval	300	Stage-2 CWM-style recipe; the stacked-video line stopped here.
ckpt_v0, ckpt_v0_dlc	—	Early baselines.

Every file without a recommended step is an intermediate checkpoint, kept as a complete record. ckpt_gather_s11/step-700 is missing because the original file was corrupted (0 bytes).
