+# MiniMax H3 Ref2Image Javawock Pack
+
+## Summary
+
+Same-day `MiniMax H3` reference-image workflow from the `javawock7618` pack. This is the most useful extra sibling in the pack if you want reusable subject and object control instead of another video variant.
+
+## Model Family
+
+- `minimax`
+
+## Status
+
+- `imported-only`
+
+## Source
+
+- Workflow pack page: <https://huggingface.co/javawock7618/comfy-MiniMax-H3-workflows>
+- Workflow file: <https://huggingface.co/javawock7618/comfy-MiniMax-H3-workflows/raw/main/extra/MiniMax_int8-Ref2Image-javano2608.2.json>
+- Original publisher: `javawock7618`

+
+## Developer notes
+
+- The graph is built around reference-role prompting, subject definitions, and a MiniMax H3 image workflow with latent upscaling.
+- It uses a large prompt-rewrite block, so the practical value is in the workflow structure rather than a tiny graph.
+- This looks closer to a reusable reference-control helper than a flashy one-off image demo.
+
+## Our notes
+
+- Good fit for the current reference-image watch area.
+- More interesting than a generic style LoRA because it is trying to preserve subject roles and reference structure.
+- Still likely heavy on an `RTX 3070` with `8 GB` VRAM, so keep expectations realistic.
