MiniMax-H3-Image-PE-NVFP4-MTP-Repacked

MiniMax-H3-Image-PE is MiniMax's prompt-expansion model for its MiniMax-H3-Image image generator. It is fine-tuned from Qwen3.8-27B and released in FP4. It turns a short request into a detailed image description and recommends an aspect ratio, returned as JSON with expanded_caption and aspect_ratio, with the output constrained to a schema by XGrammar. It runs with thinking on by default (reasoning_effort xhigh, 4,096 max tokens including reasoning), and the reasoning is returned separately. The weights cover text-to-image expansion. For image editing, the release provides only a task prompt and a message-assembly example for a vision-language model of your choice, and the card says editing support is still under development. In editing mode the model describes what is preserved and changed and returns a target_aspect_ratio. It can be served with SGLang (0.5.23 or later) or run locally through the Modular Diffusers blocks, where the FP4 weights use about 19 GiB of GPU memory. The Diffusers path runs activations in bf16, so its outputs differ slightly from the SGLang deployment. The card gives no benchmarks. The license is the MiniMax-H3-Image Community License Agreement, not Apache 2.0, and some uses need separate written authorization from MiniMax. The Qwen3.8-27B base is Apache 2.0.
