# MiniMax H3 Semantic Bridge

## Summary

Experimental MiniMax H3 conditioning adapter plus example ComfyUI workflow. This is a semantic-control path, not a new base model, and it is aimed at better prompt adherence and consistency on the standard FL2VA route.

## Model Family

- `minimax`

## Status

- `imported-only`

## Developer notes

- The repo describes this as a compact standalone adapter distilled from a teacher bridge, with the actual inference path staying inside standard MiniMax H3 conditioning.
- The example workflow is explicitly a placement reference for ComfyUI, which makes it more useful than a thin model card drop.
- The release says Ref2VA/reference-conditioned workflows are not supported in v1.

## Our notes

- This is the most interesting same-day MiniMax control release because it targets semantic structure rather than just motion.
- It looks like a real prompt-adherence helper for FL2VA, but it is still MiniMax H3, so expect it to stay tight to heavy on an RTX 3070.
- Good comparison point if you care about consistency, object relationships, or long prompt obedience more than raw style.

## Required custom nodes

- `MiniMax H3 Image to Video + Semantic Bridge`
- `MiniMax H3 Semantic Bridge`
- `MiniMax H3 Clear Semantic Bridge Cache`

## Required models

- `MiniMaxAI/MiniMax-H3`
- `MiniMaxH3_SemanticBridge_v1.safetensors`

## Notes

- Do not treat this as a Ref2VA/reference-video fix.
- Best used as a semantic-control add-on to an otherwise normal H3 FL2VA workflow.
