video with native stereo audio.
|

-
to just **4 steps** — approximately a 5x speedup. The distilled `base_schedule` `[1.0, 0.7, 0.4, 0.15, 0.0]` replaces
|
| 25 |
-
the *uniform* `linspace(1, 0, num_inference_steps)` grid `MiniMaxH3Scheduler.set_timesteps` would otherwise build, and
|
| 26 |
-
H3's per-modality exponential sigma shift still applies on top of it — a single base schedule can serve both
|
| 27 |
-
modalities precisely because it is pre-shift. So the video scheduler runs
|
| 28 |
-
σ `1 → 0.9655 → 0.8889 → 0.6792 → 0` (`shift = 12.0`) and the audio scheduler σ `1 → 0.875 → 0.6667 → 0.3462 → 0`
|
| 29 |
-
(`shift = 3.0`). Each shifted grid is injected through `MiniMaxH3Scheduler.set_timesteps(sigmas=...)`, which takes it
|
| 30 |
-
verbatim, and *pinned* onto its scheduler, because the pipeline's own denoise step calls
|
| 31 |
-
`set_timesteps(num_inference_steps, ...)` again — and for this scheduler `num_inference_steps` counts sigma grid
|
| 32 |
-
points (terminal `0.0` included), so it runs `len(sigmas) - 1` model evaluations. Pinning is the runtime equivalent of
|
| 33 |
-
`merge_lora_ckpt.py` writing `_minimax_h3.base_schedule` into `model_index.json`. Each generation reports the number
|
| 34 |
-
of Euler steps the scheduler actually took, read back off `scheduler.step_index`, rather than a hardcoded 4.

|

-
## How the LoRA is applied
|
| 46 |
-
|
| 47 |
-
The LoRA repo ships its own merge script,
|
| 48 |
-
[`merge_lora_ckpt.py`](https://huggingface.co/Beidouqixing/minimax-h3-4step-lora-flashgen/blob/main/merge_lora_ckpt.py),
|
| 49 |
-
and this Space follows it rather than a default diffusers LoRA load. The adapter is **merged** into the base weights
|
| 50 |
-
at startup — `W' = W + scale * (lora_B @ lora_A)`, accumulated in fp32, at `scale = lora_alpha / rank = 1.0`
|
| 51 |
-
(FlashGen's alpha equals its rank of 64) — instead of being attached as a runtime PEFT adapter, and all 259 LoRA
|
| 52 |
-
targets are required to resolve or startup fails, exactly as the reference script does.
|
| 53 |
-
|
| 54 |
-
The reference script merges into the *original* MiniMax-H3 partition, whose keys are the LoRA's own
|
| 55 |
-
(`blocks.N.attn.qkv_proj.weight`, `mlp.fc1/fc2`, `attn.out_proj`, `adaln_proj.linear`). Merging into the diffusers
|
| 56 |
-
port instead requires replaying the same layout transforms
|
| 57 |
-
[`convert_minimax_h3_to_diffusers.py`](https://github.com/huggingface/diffusers/blob/main/scripts/convert_minimax_h3_to_diffusers.py)
|
| 58 |
-
applied to the base weights, because a delta is only valid in the layout of the weight it is added to:
|
| 59 |
-
|
| 60 |
-
| Original LoRA target | diffusers parameter | Transform |
|
| 61 |
-
|---|---|---|
|
| 62 |
-
| `blocks.N.…` / `token_refiner.blocks.N.…` | `transformer_blocks.N.…` / `token_refiner.refiner_blocks.N.…` | rename |
|
| 63 |
-
| `attn.out_proj` | `attn.to_out.0` | rename |
|
| 64 |
-
| `mlp.fc2` | `ff.net.2` | rename |
|
| 65 |
-
| `final_layer.adaln_proj.linear` | `norm_out.linear` | rename |
|
| 66 |
-
| `adaln_proj.linear` | `adaln_proj.linear` | identity |
|
| 67 |
-
| `mlp.fc1` | `ff.net.0.proj` | fused halves swapped, `[gate; value]` → `[value; gate]` for diffusers' `SwiGLU` |
|
| 68 |
-
| `attn.qkv_proj` | `attn.to_q` / `to_k` / `to_v` | **de-interleave the per-head rows** (`[head0: q k v, head1: q k v, …]` → `[q_all; k_all; v_all]`), *then* split thirds |
|
| 69 |
-
|
| 70 |
-
That last row is the one that is easy to get wrong: the checkpoint's fused QKV rows are per-head interleaved, so
|
| 71 |
-
splitting them into contiguous thirds — the naive reading — scatters every head's q/k/v across all three projections
|
| 72 |
-
and turns the adapter into noise on all 52 attention blocks. With the de-interleave in place, the merged weights
|
| 73 |
-
reproduce `merge_lora_ckpt.py`-then-convert to within bf16 rounding.

The FlashGen LoRA (``Beidouqixing/minimax-h3-4step-lora-flashgen``) is a data-free DMD2 distillation

adapter (rank 64, alpha == rank) that reduces MiniMax-H3's T2VA inference from ~20 steps to **4**. It

``mlp.fc1/fc2``, ``attn.out_proj``, ``adaln_proj.linear``). Following ``merge_lora_ckpt.py`` — the merge

The distilled schedule ``[1.0, 0.7, 0.4, 0.15, 0.0]`` is a ``base_schedule``: it replaces the *uniform*

per-modality exponential sigma shift (``shift = 12.0`` video, ``3.0`` audio — the release's

|
| 15 |
-
modalities precisely because it is pre-shift. It is injected through

-
``MiniMaxH3Scheduler.set_timesteps(sigmas=...)``, which takes a sigma grid verbatim, so each scheduler is
|
| 17 |
-
handed ``BASE_SCHEDULE`` already pushed through *its own* shift. Note that ``num_inference_steps`` counts
|
| 18 |
-
*sigma grid points* for this scheduler (the terminal ``0.0`` included), so a 4-step schedule is 5 points
|
| 19 |
-
and the pipeline has to be asked for 5, not 4 — and because the pipeline re-runs ``set_timesteps`` itself
|

inside the denoise step, the distilled grid is pinned onto both schedulers rather than merely set before

the call.
