# MiniMax H3 Seamless Chain v2.6.0

## Summary

Same-day `MiniMax-H3` multishot workflow from `joeygambino`. This is the full
graph, not the CORE cut-down version: it adds the LLM prompt lane, remote text
encoder support, raw-latent continuity, the extend-take path, and the
speed/VRAM helper switches.

## Model Family

- `minimax`

## Status

- `imported-only`

## Developer notes

- The source README says the full pack adds Motion-Context, RES4LYF, sol-attn,
  block cache, custom scripts, and GGUF support on top of the base H3 pack.
- The workflow is built around the `ComfyUI-H3-Multishot` node pack and the
  same MiniMax-H3 weight family used by the CORE workflow.
- The current upstream release is v2.6.0 and adds the long-chain audio drift
  fix, `audio_tone_control=flatten`, `take_seconds`, `audio_pin_frames`, and
  the `H3_Extend_Take` workflow.
- The prompt-writer lane expects a `qwen3:14b`-class local or remote
  OpenAI-compatible endpoint if you keep it enabled.

## Our notes

- This is the more interesting same-day MiniMax import if you want the full
  feature set and are willing to pay for it in complexity.
- On an `RTX 3070 8 GB`, this is a heavy workflow, but the memory and remote
  encoder options are the kind of practical extras that make it worth keeping.
- The v2.6.0 audio fixes make this the strongest MiniMax H3 roundup item
  today.
- If you want the simpler starting point, the CORE workflow is still the
  cleaner local baseline.

## Required custom nodes

- `ComfyUI-H3-Multishot`
- `ComfyUI-H3-Motion-Context` for the context-pin lane
- `RES4LYF`
- `ComfyUI-sol-attn`
- `comfyui-minimax-h3-blockcache-T8`
- `ComfyUI-Custom-Scripts`
- `ComfyUI-GGUF` if you run GGUF weights

## Required model files

- MiniMax-H3 weights from `Comfy-Org/MiniMax-H3`
- matching MiniMax-H3 text encoder and audio/video VAEs from the same family
- optional `qwen3:14b`-class prompt-writer model or endpoint if the LLM lane
  stays enabled

## Notes

- Load `workflow.json` directly in ComfyUI.
- Best kept as the full-feature reference for MiniMax H3 multishot work.
