Introducing ManimGX, the 3D animation engine for agents. - Blazingly fast: 90× faster than ManimCE - Rust + wgpu core - Compatible with Manim's Python API - Lightweight: one pip install, no system dependencies Open source: Docs: For 40 years we built GUIs for humans. Now we build APIs... for agents. Try it. Paste this into your favorite coding agent: "Follow to make me a 3D animation of the solar system, and open it."show more

How fast? 36 s of 1080p60 video in 3.1 s, from launch to finished MP4. 90.6× faster than ManimCE 11.5× faster than ManimGL 18.7× faster than Blender Workbench Method:

Made for agents: - manimgx inspect (CLI command): storyboard PNGs your agent checks before rendering the video - 2D layout checks: content cut off, text overlapping or too small, by variable and line - Fully statically typed: TypedDict keyword arguments, typed .animate chains

pip install manimgx. That's the whole setup on macOS, Windows and Linux (Python 3.13+): 65–110 MB download, and no system dependencies like LaTeX or FFmpeg. It runs in the browser too: npm install manimgx, and Pyodide and WebGPU render the scene.

Voiceover support, built in. self.say() speaks a line and starts each animation at its words in brackets: self.say("The derivative of [x squared] is [two x].", anim1, anim2) Any text-to-speech service can be the voice, and render writes the captions.

Thanks to the giants we stand on: Grant Sanderson (@3blue1brown), who created Manim, and @manimcommunity, whose API ManimGX targets. And to the projects we build on: wgpu, Google's Filament, Typst, mitex, x264, FFmpeg, libopus, Pyodide and Mesa. And to @fal for sponsoring us.

That will get my infra bill down by 90x

This is the reply I’ve been waiting for 😎

can this make more commonplace 3d videos than just math and science concept vids? sounds impressive, but doesn't look too practical for most cases

Technically, it can make anything that can be created with 3D computer graphics. Though, we'll keep improving the API with better abstractions, such as 3D modeling operations like extrusion, revolution, boolean operations, like CAD software.

im actually gonna test this on a vid im editing now

Share the results!

Oh trust I plan too for my YT channel growth

Made this with ManimGX: 25 layered torus knots, rotating and breathing in a 12s loop. Loop recipe: integer particle revolutions + periodic deformation + matching camera endpoints. The equations describe the motion. Thanks for building this, @sinaatalay!

I gave Claude the link of my public repository which is a remote controller for MacBooks, and asked it to use manimgx to create promo gifs to showcase the features. I was shocked how good the results were!!

insane edu alpha in videos rendered fast enough that you can actually ask followup questions live tried this out while refreshing myself w/ CMU's 15-213 slides on memory hierarchy and it's about 60-90s from question to beautiful visuals (bottlenecked by agent speed)

you rock man, thanks for open sourcing it

I call it the best 3D animation engine in history!

Holyyyyy this is insane I gotta test it out

That's impressive.

This is nuts! And the narration is just incredible. The storytelling. Is that Eleven labs voice ?

Thank you! Yes, it's ElevenLabs v4.

Amazing!

Great great great work

here is the video

This is amazing

looks pretty awesome well done making it faster than blender would you say it's more suited to scientific anims?

AI is so general that I don't think ManimGX should be limited to scientific use cases. We envision ManimGX as a way to create any video that can be made with 3D computer graphics. But thanks to its math typesetting support and all the features Manim has developed over the years, it's quite capable for scientific purposes.

looks cool. have u compare the quality with blender or threejs with same ai agent. and can you recommand tools for 3d modeling . i used blender and feel it not so gokd for agent use

Yes, ManimGX's quality is very comparable to Blender's.

thanks .bender is too slow , manimGX will be better tool

Building 3D animation tools for agents is a smart move. Excited to see what creators build with this!

Now I can be 3b1b

rust core with python API is exactly how you build tooling in 2026

massive speed boost, perfect for agent pipelines. gonna test on my LLM workflow

Add us as the audio layer and take your video to the next level

I bet audio as code will be huge soon too. I'll check out your work!

Looking forward for your feedback!

老的 Manim 脚本能直接跑吗，手头攒了不少

Used luna. Thank you very much 🙏

the storyboard checks before rendering sound useful can it flag when text is only on screen too briefly to read

@izzyjhlee you should take a look

great

90x faster is wild — love the API-for-agents angle

rust사랑해

90倍？？卷疯了

Shipping a Rust and wgpu core that keeps the Manim Python API, with an llms.txt so a coding agent can drive it from one prompt, is a smart way to lower the switching cost. I would be curious how you keep the output frame accurate against ManimCE as the 3D feature set grows.

Pretty sick stuff

Making 3D animation easier for AI agents is a smart move.

my SI said to download it :)
