3Blue1Brown parody on how LLMs work
A three-minute vertical parody of a 3Blue1Brown math explainer about how LLMs work, in which the narrator slowly gives away that he has no idea. Claude Code wrote and rendered it from a one-sentence prompt, with ElevenLabs narration.
“To be clear, the model doesn't output video directly. It writes the code, renders it, and orchestrates tools like TTS and video models to put the final result together.”
Do a funny 3blue1brown parody video about how LLMs work where it becomes increasingly clear the narrator doesn't know what he's talking about
Make it yours. Swap "how LLMs work" for your own topic, and change the running joke in "where it becomes increasingly clear the narrator doesn't know what he's talking about".
You'll need
- An ElevenLabs API key for the narration
How it was made
The creator gave Claude Code an ElevenLabs API key for the narration; otherwise the prompt was this one sentence. They don't name the animation library. Commenters guessed Manim, which the creator didn't confirm.

A black-background math-explainer pastiche in vertical format: serif titles and simple diagrams for each LLM concept, bold captions, and two pi-shaped characters, one teal and one brown, watching from the bottom corners.
- Color
- Black, white, teal, and brown, with yellow for highlights and arrows and small dots of pink, orange, and green in the scatter plots.
- Type
- A classic serif for headings and diagram labels ("Tokens", "Embeddings", "Attention", "Gradient descent"), heavy rounded sans-serif captions, and a red rubber stamp reading "CITATION NEEDED".
- Framing
- 9:16 frame with a heading and diagram in the upper half, a two-line caption at mid-height, and the two characters in the bottom corners.
- Sound
- ElevenLabs narration, according to the creator.
- Structure
- "The cat sat on the" fed into an LLM box with a question mark, "straw" and "berry" tokens, an embeddings scatter plot, king and queen vector arrows stretched to "cowboy" minus "cow", attention lines from "it" to "cat", a grid of parameter dials ("Little knobs."), a ball on a "wrongness" curve for gradient descent, a hallucination card with a fake "Albert Einstein, 2021" quote stamped "CITATION NEEDED" ("Great catch. You're absolutely right."), and a closing title being drawn.
