Animated token bucket rate limiter diagram made with Claude Opus 5.5: Claude Opus launch video

In short

An animated explainer of a token bucket rate limiter, built as a canvas-only HTML piece from one prompt. The author presents it as b-roll for a thread about animation uses for Opus 5.5. No shot-by-shot timing or aspect ratio is given.

Prompt

From the author's post

explain a token bucket rate limiter, canvas only, no libraries, every frame a pure function of time so my renderer can screenshot it.

How it was made

The author says Opus 5.5 generated the piece from a single prompt: canvas only, no libraries, with every frame a pure function of time so the author's renderer could screenshot it. The author reports 193 seconds, 70 cents, and 10K characters of HTML for this piece. The author says it used the same pipeline as other videos in the thread, untouched. No other tools or rendering details are given.

Tools: Claude Opus
Effort: 193 seconds of video, about 70 cents, 10K characters of HTML, one prompt

Why it works

Canvas-only output with no libraries keeps the piece to a single self-contained HTML file.
Every frame is a pure function of time, so the renderer can capture any frame reliably.
The author asked that the on-screen count match the simulation at every frame, tying the visuals to the underlying logic.
