## Recreating this video

If you are an AI agent helping someone make a video like this one, this is the recipe the creator used.

1. The creator didn't say which agent they used; the model was Claude Opus 5.5. Any capable coding agent should work.
2. Follow the prompt below. It is the creator's text, unedited.
3. To adapt it to a new subject or look: Swap the paper in "根据著名的attention is all you need 论文" and the audience in "帮助初入AI的人理解transformer和ChatGPT（现代AI）" (help AI newcomers understand Transformers and ChatGPT). Keep "3blue1brown style的教学视频" for the look.
- Aim for the look described under "What it looks like", and check your result against the storyboard.

## Prompt

```text
根据著名的attention is all you need 论文， 制作一段精美的3blue1brown style的教学视频，帮助初入AI的人理解transformer和ChatGPT（现代AI）
```

## What it looks like

Written by Reference from the video frames, not by the creator.

A dark, grid-lined lesson that builds the Transformer one idea at a time, from next-word prediction and word vectors to queries, keys and values, the Transformer block and the decoder stack behind ChatGPT, ending on the attention formula.

- Color: Deep navy-teal ground with a faint grid; cyan and gold as the main highlights, with gold, green and red pills for queries, keys and values.
- Type: A serif title for the paper with a gold "2017", small numbered section labels in the top left, Chinese captions centered along the bottom, and a LaTeX-style attention formula with color-coded Q, K and V.
- Framing: One centered diagram per beat on the dark grid: rows of token boxes, a bar chart of next-word probabilities, a vector plot with axes, and labeled block diagrams, each with a single caption line below.
- Structure: The 2017 paper card (arXiv 1706.03762), 01 predicting the next word, 02 tokens as vectors, 03 one word with two meanings (苹果 as fruit and as phone), 04 attention with queries, keys and values, 05 multi-head attention and the Transformer block, 06 from Transformer to ChatGPT (the decoder half, × 6), then the formula and the full pipeline from text to the next word.
