    MiniMax H3 正式开源:通用全模态生成系统支持 2K 视频与原生立体声

    MiniMax 正式开源新一代通用视频模型 H3,可统一理解文本、图像、视频和音频,生成最高 2K 分辨率、最长 15 秒、带 32 kHz 原生立体声音频的视频。

    推荐理由:与多数开源视频模型不同,H3 原生支持同步生成立体声音频,且通过上下文再生成实现 2K 分辨率,为音视频生成应用提供了更完整的开源基座。

    MiniMax 宣布其视频生成模型 H3 即将开源(open weights)。有用户反馈,H3 生成视频的质量和数量均优于 2.5 版本,且成本更低、推理速度更快、自定义音频上传功能正常。该用户认为,在创意工具领域,成本与速度最终将决定胜负,规模化后有望实现无限生成。

    引用𝔹𝕃𝕍ℂ𝕂𝕃!𝔾ℍ𝕋@BLVCKLIGHTai

    I’m seeing way better videos coming from H3 than 2.5 on the timeline. And more of them. I think cost is a big part of it, plus the speed of inference, and custom audio uploads working as intended. My thesis holds still that at a certain point unless you are actually fixing the pressure points creatives have with your tools, cost and speed are going to win. Unlimited generations are NOT a pipe team. It all comes down to hourly costs divided by users. At some point if you can scale you’ll run at a surplus and can run unlimited.

    MiniMax H3:一款打破任务与模态边界的开源模型 [引用 @RenLeanna]:这恰好印证了我们的训练方法论:语言/图像/视频/音频都是人类经验中深度互联的模态。而多模态智能应植根于语言——一种可泛化、可扩展的计算系统。 真的很感谢你挖出这个!🙌

    引用Leanna Ren@RenLeanna

    This exactly echoes our training methodology: language/image/video/audio are all deeply interconnected modalities of human experience. And multimodal intelligence should be grounded in language which is a generalizable and scalable computational system. Really, really appreciate you digging this up!🙌

    MiniMax 发布开源权重视频模型 H3,在 Artificial Analysis 视频编辑榜登顶,文本生视频排名第二、图像生视频排名第三。H3 支持文本、图像、视频、音频统一输入,原生生成 2K 24fps 5-15 秒带立体声片段,定价每分钟 2K 视频 $7.80,远低于 Seedance 2.0 的 $22.45 和 Kling 3.0 的 $20.16。

    引用MTS@MTSlive

    SITUATION EXPLAINED: MiniMax released H3 with open weights, and it's already #1 in video editing. • Priced at $7.80 per minute of 2K video, against Seedance 2.0 at $22.45 and Kling 3.0 at $20.16 • It ranks #1 on Artificial Analysis for video editing, #2 for text-to-video behind Gemini Omni Flash, and #3 for image-to-video • H3 takes text, images, video, and audio in a single context and generates 5-15 second clips at native 2K, 24fps, with native stereo audio • MiniMax is releasing the weights under its Community License within days, which would make it the strongest open-weights video model by a wide margin • It launched the same week ByteDance rolled out Seedance 2.5, which now generates 30-second 4K video from a single prompt • Seedance 2.5's face consistency across a full 30 seconds is the visible jump, earlier models drifted into a different face partway through • Voices are still the obvious tell, the video reads as real long before the audio does • Smaller labs building purpose-built video models are now beating frontier labs at this specific task @theojaffee: "This is gonna be one of the biggest examples of things that people are gonna do with these models, historical simulations, basically. Nostalgia videos for zoomers."

    1-bit Kimi K3 performs at Opus 5 level on 3D physics! We ran our Atomic Chat quant of Kimi K3 locally on 4x B200 against three cloud models and gave them all the same task, to build a giant anvil drop test as a single HTML file with real physics Outputs: K3 1bit (local): 15.8K tokens, $0 API cost Kimi K3 (API): 15.3K tokens, $0.30 API cost Opus 5: 22.8K tokens, $0.77 API cost GPT 5.6: 14.5K tokens, $0.72 API cost All four got the physics right. But only Kimi made a working winch. The drum turns and the chain drags the flat car off the pad. Opus 5 drew the most detail, road markings and sparks on the hit. And you can run a model at this level on your own box now. That still feels insane to us
