+
+## Summary

+`MiniMax H3` workflow focused on ease of use, int8 convrot pieces, and a lower-memory path for local testing.

+
+## Developer notes
+
+- The model card says V2 adds an int8 convrot video VAE, memory chunks, and a Kijai resized turbo LoRA.
+- The author notes the workflow was already near the cap for `16 GB` VRAM, so this is not a tiny setup.
+- It requires several community custom node packs rather than only stock ComfyUI.
+
+## Our notes
+
+- This is one of the more serious MiniMax releases of the day because it is clearly trying to make H3 easier to run, not just more flashy.
+- On an `RTX 3070 / 8 GB`, it still looks heavy, but the memory-saving tricks make it worth keeping on the radar.
+- If MiniMax starts feeling close to practical, this is a stronger watch item than the generic wrappers.
+
+## Required custom nodes
+
+- `ComfyUI-PlagueKind-Nodes`
+- `ComfyUI-KJNodes`
+- `rgthree-comfy`
+- `Nvidia_RTX_Nodes_ComfyUI`
+- `ComfyUI-VideoHelperSuite`
+- `SageAttention`
+
+## Required models
+
+- `Comfy-Org/MiniMax-H3`
+- `Kijai/MiniMax-H3-experimental`
+- `Comfy-Org/frame_interpolation`
+- `Kijai/MiniMax-H3_comfy`
+
+## Notes
+
+- Best same-day MiniMax workflow for a more tuned local-test path.
