# MiniMax H3 — weights log (B200 pod `c306014998a3`, 216.243.220.136)

All files from **[Comfy-Org/MiniMax-H3](https://huggingface.co/Comfy-Org/MiniMax-H3)** (ComfyUI repack of
[MiniMaxAI/MiniMax-H3](https://huggingface.co/MiniMaxAI/MiniMax-H3)). Two model lines:
**fl2va** (text-to-video + first/last-frame i2v) and **ref2va** (reference-to-video).
ComfyUI finds both storage locations via `/ComfyUI/extra_model_paths.yaml`
(installed from `scripts/pod/extra_model_paths.yaml`).

## Storage locations

| Path | Medium | Notes |
|---|---|---|
| `/workspace/minimax-h3/models/` | RunPod network volume | **Persistent.** Volume has a ~100 GB quota — it is full; don't add files without removing others. |
| `/dev/shm/minimax-h3-models/` | tmpfs (RAM, 176 GB) | **EPHEMERAL** — wiped on pod restart. Refill with `bash /workspace/minimax-h3/download-weights-tmpfs.sh`. |

## Downloaded files

### Persistent — `/workspace/minimax-h3/models/`

| File | Family | Size |
|---|---|---|
| `diffusion_models/minimax_h3_ref2va_pruned_int8_convrot.safetensors` | **int8 pruned** (ref2va) | 21 GB |
| `diffusion_models/minimax_h3_fl2va_pruned_int8_convrot.safetensors` | **int8 pruned** (fl2va) | 21 GB |
| `diffusion_models/minimax_h3_ref2va_int8_convrot.safetensors` | **int8** (ref2va) | 34 GB |
| `text_encoders/qwen3vl_32b_minimax_h3_nvfp4_awq.safetensors` | text encoder (Qwen3-VL-32B, nvfp4 AWQ) | 16 GB |
| `vae/minimax_h3_video_vae_fp16.safetensors` | video VAE fp16 | 5.2 GB |
| `vae/minimax_h3_audio_vae_fp32.safetensors` | audio VAE fp32 | 0.6 GB |

### Ephemeral (tmpfs) — `/dev/shm/minimax-h3-models/`

| File | Family | Size |
|---|---|---|
| `diffusion_models/minimax_h3_fl2va_int8_convrot.safetensors` | **int8** (fl2va) | 34 GB |
| `diffusion_models/minimax_h3_ref2va_bf16.safetensors` | **bf16** (ref2va) | 66 GB |
| `diffusion_models/minimax_h3_fl2va_bf16.safetensors` | **bf16** (fl2va) | 66 GB |

The int8 family is split across both locations purely because of the volume
quota: ref2va_int8 landed on the volume before it filled, fl2va_int8 overflowed
to tmpfs.

## Not downloaded (exist upstream)

| File | Size | Why skipped |
|---|---|---|
| `diffusion_models/minimax_h3_{fl2va,ref2va}_pruned_bf16.safetensors` | 40 GB each | 4th family (pruned but unquantized); not in the 3 families requested |
| `diffusion_models/minimax_h3_{fl2va,ref2va}_pruned_fp8_scaled.safetensors` | 21 GB each | 5th family; same size class as pruned int8 |
| `text_encoders/qwen3vl_32b_minimax_h3_bf16.safetensors` | 52 GB | nvfp4_awq TE is the one every official template uses |
| `text_encoders/qwen3vl_32b_minimax_h3_int8_convrot.safetensors` | 27 GB | same |

## History / gotchas

- 2026-08-06: original manual download of ref2va_pruned_int8 had a broken
  filename (`...safetensors?download=true` from a wget of the HF web URL); byte
  size matched HF exactly so it was renamed + moved to the volume, not re-downloaded.
- 2026-08-06: bf16 + fl2va_int8 downloads to the volume failed with
  `Disk quota exceeded` at ~93 GB used → tmpfs overflow scheme added.
- Downloads log: `/workspace/minimax-h3/download.log`.
