+# MiniMax H3 Seamless Chain v2
+
+## 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, and the speed/VRAM helper switches.
+
+## Model Family
+
+- `minimax`
+
+## Status
+
+- `imported-only`
+
+## Source
+
+- Workflow pack page: <https://huggingface.co/joeygambino/MiniMax-H3-Multishot-Workflow>
+- Workflow file: <https://huggingface.co/joeygambino/MiniMax-H3-Multishot-Workflow/resolve/main/workflows/H3_Seamless_Chain_v2.json?download=true>
+- Original publisher: `joeygambino`
+- Date imported: `2026-08-16`
+
+## 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 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.
+- 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.
