# MiniMax H3 INT8 R2V Javawo 2608.23

## Summary

Same-day `MiniMax H3` reference-to-video workflow from the `javawock7618` pack. This is the newest R2V variant in that collection and the most directly useful current MiniMax consistency path.

## Model Family

- `minimax`

## Status

- `imported-only`

## Source

- Workflow pack: <https://huggingface.co/javawock7618/comfy-MiniMax-H3-workflows>
- Workflow file: <https://huggingface.co/javawock7618/comfy-MiniMax-H3-workflows/resolve/main/MiniMax_int8_R2V-javano2608.23.json?download=true>
- Original publisher: `javawock7618`
- Date imported: `2026-08-20`

## Developer notes

- The pack positions this as an `INT8` reference-to-video workflow with:
  - `Sol-Attn`
  - `Spectrum`
  - optional `Lightx2v LoRA`
  - optional `Turbo-LoRA`
  - native `Extend`
  - latent upscaling
- The source README says the R2V graph uses the reference LoRA:
  - `minimax_h3_ref_lora_rank_256_bf16.safetensors`

## Our notes

- This is the strongest same-day MiniMax import for character retention and reference control.
- It still looks heavy for an `RTX 3070`, but it is a real low-VRAM-oriented path rather than a generic full-fat MiniMax demo.
- Good fit for testing whether MiniMax H3 is now practical enough for local reference-video work.

## Required custom nodes

- `ComfyUI-SolAttn_triton`
- `ComfyUI-Spectrum-MiniMax-H3`
- `ComfyUI-MiniMaxH3_LatentUpscaler`
- `ComfyUI-KJNodes`
- `ComfyUI-Easy-Use`
- `ComfyUI-VideoHelperSuite`

## Required models

- `Comfy-Org/MiniMax-H3`
- `minimax_h3_ref_lora_rank_256_bf16.safetensors` from `Kijai/MiniMax-H3-experimental`
- `lightx2v/Minimax-h3-Turbo` if you enable the acceleration path
- `drbaph/MiniMax-H3-Turbo-Lora-ComfyUI` if you enable the optional turbo LoRA

## Notes

- Best same-day MiniMax workflow for reference retention and identity control.
- Still experimental, but the most practical current MiniMax video path in this repo.
