One prompt, 80 minutes: Opus 5.5 autonomously produced a collage-style animation for ~$20
Singularity-42 · reddit · 2026-09-24
A Reddit user replicated a viral X demo of Opus 5.5 generating an animation from a single prompt, and claims the result came out even better. After issuing one prompt, the model worked fully autonomously for about 1h20m to produce a 30-60s hand-drawn collage-style animation with audio on "what is the purpose of life?"
Cost breakdown: $20 of Opus 5.5 spend (about 10% of a Max 5 subscription's 5-hour budget) plus $3.21 via OpenRouter across 8 different APIs — mostly NanoBanana 2 for images, then text-to-speech and a few cents for other services.
The prompt itself is the interesting artifact: it demands pure JavaScript animation, professional production value, internet access, full autonomy, and caps OpenRouter spend at $10 via an API key in .env — budget constraints written directly into the instruction. The author notes it's a true one-shot result with a few things still to fix.
