MiniMax H3 — weights log (B200 pod c306014998a3, 216.243.220.136)
Status as of 2026-08-06 04:35 UTC.
Source
All files downloaded from the HuggingFace repo
Comfy-Org/MiniMax-H3 (the
ComfyUI repack of MiniMaxAI/MiniMax-H3),
e.g. https://huggingface.co/Comfy-Org/MiniMax-H3/resolve/main/<path>.
Downloaded with hf download + hf_transfer by scripts/pod/download-weights.sh
and download-weights-tmpfs.sh; log at /workspace/minimax-h3/download.log.
There are two model lines — fl2va (text-to-video + first/last-frame i2v)
and ref2va (reference-to-video) — each published in several precisions.
ComfyUI finds both storage locations below via /ComfyUI/extra_model_paths.yaml
(installed from scripts/pod/extra_model_paths.yaml).
Storage locations on the pod
| Path | Medium | Notes |
|---|---|---|
/workspace/minimax-h3/models/ |
RunPod network volume | Persistent. The volume has a ~100 GB quota and is effectively full. |
/dev/shm/minimax-h3-models/ |
tmpfs (RAM, 176 GB) | EPHEMERAL — wiped on pod restart. Refill with bash /workspace/minimax-h3/download-weights-tmpfs.sh (~10 min). |

diffusion_models/minimax_h3_fl2va_int8_convrot.safetensors |
int8 (fl2va) | 34 GB |
diffusion_models/minimax_h3_ref2va_bf16.safetensors |
bf16 (ref2va) | 66 GB |

bf16 (fl2va) | 66 GB |
The int8 family is split across the two locations only because of the volume quota: ref2va_int8 landed on the volume before it filled; fl2va_int8 and both bf16 files overflowed to tmpfs.
In progress: none. All nine files above are fully downloaded (sizes byte-verified against the HF API).
Not downloaded (exist upstream in the same repo)
| File | Size | Why skipped |
|---|---|---|
diffusion_models/minimax_h3_{fl2va,ref2va}_pruned_bf16.safetensors |
40 GB each | a 4th family (pruned, unquantized) — not in the 3 requested families |
diffusion_models/minimax_h3_{fl2va,ref2va}_pruned_fp8_scaled.safetensors |
21 GB each | a 5th family — same size class as pruned int8 |
text_encoders/qwen3vl_32b_minimax_h3_bf16.safetensors |
52 GB | every official template uses the nvfp4_awq TE; bf16 TE would also not fit the volume quota |
text_encoders/qwen3vl_32b_minimax_h3_int8_convrot.safetensors |
27 GB | same |
History / gotchas
- 2026-08-06: the pre-existing manual download of ref2va_pruned_int8 had a
broken filename (
...safetensors?download=truefrom a wget of the HF web URL); byte size matched HF exactly, so it was renamed and moved to the volume rather than re-downloaded. - 2026-08-06: bf16 + fl2va_int8 downloads to the volume failed with
Disk quota exceededat ~93 GB used → tmpfs overflow scheme added. - After any pod restart: tmpfs weights are gone; ComfyUI will still boot
(extra_model_paths tolerates the missing dir) but the bf16/fl2va-int8 entries
disappear from loader dropdowns until
download-weights-tmpfs.shis re-run.
