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.

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.
