Thank you very much! That’s strange, we’ll look into it. Really appreciate you reporting it.

The lecture description language isn’t public at the moment. It’s a core part of the technology we’re building the company around.

Also, if you’d like, you can share the video as a public link by clicking the share button!

We ask Claude Opus 5 to write a specific kind of source code that only our proprietary software understands and can render into a lecture video with computer graphics and TTS.

Without our system, there isn’t really an equivalent target language you can ask the LLM to write. Manim exists, but you won’t get videos like these by simply asking an LLM to generate Manim code.

Thank you!

Actually, the economics are quite good.

We’re not using video generation models. We ask an LLM to write the lecture as code, then render it deterministically with computer graphics and TTS.

So the main costs are the LLM call, TTS, and some cloud GPU time for rendering. That ends up being much cheaper than generating long form video directly with video models.

You can attempt to do it, but you'll see that it won't work. We've built the underlying "lectures as code" technology to make this work.

Claude Opus 5, with high thinking, generates the video in a single shot.

The one that asks questions at the beginning is Gemini Flash 3.7.

On consumer devices, AI communicates with us through speakers and screens. Screens are the richer medium, so most consumer AI innovation will happen there.

Computer graphics will have enormous applications because they are directly controllable by LLM-generated code. Video models are probabilistic and less suitable when precision matters. In education, for example, we need exact visuals. If an AI wants to plot y = sin(x), it should generate the precise graph through computer graphics rather than approximate it with a video model.

Sorry about that paywall. We've made the AI chat free up to a certain usage limit, so if you're interested, you can give it a try now!

Thank you for letting us know about the Safari issue.
