<p><strong><a href="https://github.com/PipeNetwork/minimax-h3-mlx">PipeNetwork/minimax-h3-mlx</a></strong></p> MiniMax released <a href="https://huggingface.co/MiniMaxAI/MiniMax-H3">MiniMax-H3</a> two days ago - they describe it as a "a general-purpose, omni-modal generative system", which in practice means it accepts text, images, audio and video and can use them to generate up to 15 second video clips with audio included.</p> <p>This Python package ports it to MLX for running on Apple Silicon.</p> <p>I got it running on my M5 Max MacBook Pro. I cloned the repo and ran the model like this:</p> <pre><code># First download the models uvx --from huggingface_hub hf download MiniMaxAI/MiniMax-H3 \ --include 'FL2VA/*' --exclude 'FL2VA/transformer/*' uvx --from huggingface_hub hf download pipenetwork/MiniMax-H3-MLX-8bit # Now run the prompt uv run --with mlx-vlm \ --with-requirements requirements.txt python scripts/generate.py \ "a rainbow colored skunk leaps over a mossy log in a supermarket" \ -o skunk.mp4 \ -c ~/.cache/huggingface/hub/models--MiniMaxAI--MiniMax-H3/snapshots/fa9c8ab1eaa21c8ae25e7e40b83b2e6002f340af/FL2VA \ -t ~/.cache/huggingface/hub/models--pipenetwork--MiniMax-H3-MLX-8bit/snapshots/3ac52081470b0488921c3ec3ba84a39097bf2361 </code></pre> <p>Here's the video I got for the prompt:</p> <blockquote> <p><code>a rainbow colored skunk leaps over a mossy log in a supermarket</code></p> </blockquote> <p><video controls loop preload="none" poster="https://static.simonwillison.net/static/2026/skunk.jpg" width="1344" height="768" style="display: block; width: 100%; height: auto;" > <source src="https://static.simonwillison.net/static/2026/skunk.web.mp4" type="video/mp4"> Your browser does not support HTML5 video. </video> </p> <p>It downloaded ~115 GB of model files, and the video generation took just under 45 minutes.</p> <p>The video is impressive, but the audio is weird speech-like garbage, because I didn't provide any prompt guidance as to what the audio should be. The <a href="https://huggingface.co/MiniMaxAI/MiniMax-H3/blob/main/docs/VIDEO_PROMPT_WRITING_GUIDE_base_en.md">prompting guide</a> (which I didn't read prior to this experiment) has a whole bunch of information on how to get this to work. <p>Tags: <a href="https://simonwillison.net/tags/ai">ai</a>, <a href="https://simonwillison.net/tags/generative-ai">generative-ai</a>, <a href="https://simonwillison.net/tags/mlx">mlx</a>, <a href="https://simonwillison.net/tags/text-to-video">text-to-video</a>, <a href="https://simonwillison.net/tags/minimax">minimax</a></p>
