Claude vs Codex — a pixel-art cartoon written entirely in code

Generated by the new Claude Opus in Claude Code — **one-shot, 1 user turn**, ~5.5 hours of wall-clock time.

![cover](cover.jpg)

A 93-second, 1080p, 30 fps cartoon about Clawd (the Claude Code mascot) and the Codex pet: they argue over who is better, duel in code, race, get caught in the rain, make up and watch the sunset.

There is no video editor, no After Effects and no image generation here. Every frame is computed by ~15 000 lines of Python + NumPy that Claude wrote in one turn: a tiny pixel engine, a Mode-7-style 2.5D camera, eight scenes, a chiptune synth and a mixer. The complete result — picture, sound design, music, credits, cover and English version — was made as a one-shot.

One-shot prompt

make a cool cartoon 16:9. make it with code.

in the cartoon - clawd (the claude code mascot, pull him out of the bundles and the claude app) and codex (the codex pet, pull him out of the codex app pets too)

well basically the vid is like they at first argue like I'm better, no I'm better. and then by the end they make up and sit cute at sunset hugging. different scenes.

world is pixel so make both of them fit in nicely (they’re both pixel), you can generate the world background and stuff and elements via fal if you want, or you can do it yourself.

make it in 2.5d. with sounds and music. no voiceover. you can use subagents.

Build it

macOS, Python 3.10+, `ffmpeg`, `node` (for `npx`), and the Claude and ChatGPT desktop apps installed (the character sprites are taken from *your* copies — see below).

pip install -r requirements.txt
./make.sh                    # Russian version  -> out/claude_vs_codex_ru.mp4
LANG_CARTOON=en ./make.sh    # English version  -> out/claude_vs_codex_en.mp4

Rendering takes about two minutes on an M-series Mac (8 worker processes). The output is pixel-identical to the published video — `tools/compare.
