AI Glossary
H3 is a multimodal generation model developed by MiniMax, capable of generating high-resolution video and supporting unified context understanding for text, images, video, and audio.
Ant Group inclusionAI · Hugging Face new modelsinclusionAI releases Duo 1.0 causal-base model, a full-duplex multimodal world model for real-time audio-video interaction, including implementation weights and backbones, intent models and adapters, audio-video encoders, speech recognizers, and forced aligners. The model weights are based on MiniMax H3 initialization and are open-sourced.
Comfy BlogMiniMax H3 Image now natively supports ComfyUI, offering 4096×4096 high-resolution output, supports text-to-image generation and reference image editing, and can also be run directly through Partner Nodes.
The RunningHub platform under Haiyun, through self-researched computing power pools and vertical model post-training, increases computing power utilization to over 70% in the industry, launching RH Upscale super-resolution models, H3 Lightning video generation models, etc., achieving low-cost, high-efficiency AI content production. The platform integrates Agents, tool chains, and expert knowledge context, supporting dynamic model routing and intelligent orchestration, allowing users to complete professional-level tasks without complex operations, with a monthly token consumption of 900 billion.
NVIDIA and MIT team open source video enhancement solution Open-H3-Regenerate-2K, based on MiniMax H3 model to regenerate low-resolution video to 2K (2560×1440) or 4K (3840×2160) video.
Comfy Blog7070Using the FastVideo FastH3 V2 checkpoint, it generates 15-second 448×256 resolution video on a single RTX 5090 GPU through optimizations like four-step sampling, sparse attention, small text encoders, small checkpoints, and fused FP4 MLP. VRAM requirements are reduced from 80GB to <30GB; this custom Comfy node is open-sourced and can be deployed by requesting GPU and models via Comfy API.
MiniMax NewsMiniMax has released the H3 model, supporting unified context understanding for text, images, video, and audio, capable of generating 2K resolution video with native stereophonic sound (up to 15 seconds long).
MiniMax · Hugging Face new modelsMiniMax-H3 is a general multimodal generation system that supports unified understanding of text, images, video, and audio, capable of generating video with up to 2K resolution and up to 15 seconds of stereoscopic audio. Its H3-Context-IR module is used for deep understanding of input commands and converting them into an intermediate representation understandable by H3-Base, but it is not open source. The H3-Base and H3-Regenerate-2K modules are responsible for audio and video generation at 768p and 2K resolutions, respectively; the former is open source, while the latter requires API calls.
