MiniMax H3 开放权重发布，社区测试活动升温

MiniMax has introduced H3, its latest multimodal AI model capable of understanding text, images, video, and audio within a unified context to generate high-quality videos with native stereo sound. The model supports up to 15-second videos in 2K resolution, offers advanced editing capabilities such as motion transfer, image-to-video, and video-to-video generation, and is designed for commercial applications including advertising, e-commerce, product design, gaming, and UI/UX. MiniMax also plans to release H3 as an open-weight model, giving developers greater flexibility to customize and deploy it. The company claims H3 delivers industry-leading price-performance, producing premium-quality videos at a significantly lower cost than competing models. H3 is built on a unified multimodal [...] Together, these developments highlight how AI is evolving beyond static models toward systems that can create, learn continuously, and interact intelligently with the physical world. ## MiniMax H3 Unv

Closed-source models have long dominated video generation, with slower iteration and a less open ecosystem than fields like large language models. To support the open-source community, accelerate compatibility with a broader range of AI hardware, and make it easier for users to build their own customized versions, we plan to open up the model weights in the coming days, subject to applicable laws and regulations. Hardware compatibility has been a key consideration since the earliest stages of H3's design. ### Multimodal context understanding [...] AIH3MultimodalVideo Generation Today, we're launching MiniMax H3, a general-purpose multimodal generation model. H3 understands unified context across text, images, video, and audio, generating video with native stereo sound, up to 15 seconds at 2K resolution. Early testing shows H3 is ready for commercial content creation across a wide range of use cases, excelling at instruction following, accurate text and brand rendering, and V2V motio

Ranked #1 in video editing and top-3 in text-to-video. But they didn't open-source all of it. In this video: which of the six weight variants to actually download (and the trap that wastes 45GB), the two-checkpoint catch, real speed and VRAM numbers from my RTX 5090, the prompt structure that replaces the closed Context-IR module, and my honest verdict vs LTX 2.3. 📥 Workflows, exact settings & the prompt template: Codebreakers site: 🔔 Subscribe — to keep up to date with latest drops!

Their servers regenerate the 768p output at 2K and that one you generally can't have locally. So, we top out at native 768p and then upscale with our own tools, which is what every result in this video is. That's the truth of it. Astra, give people the numbers. T
