Made entirely with Opus 5.5 + OpenRouter API key
Reddit users report one-shot production of 30-60s hand-drawn collage-style animated videos by running a single shared prompt through Claude Code with Opus 5.5, letting it autonomously orchestrate scripting, asset generation, animation, and text-to-speech via OpenRouter APIs. The original run took about 1h20m and roughly $23 in combined model spend; a follow-up replication produced a full English explainer for a real product in 1.5-2 hours for about $4. The results demonstrate Opus 5.5 handling multi-step agentic creative work unattended.

User creates 15-second motion graphics showreel with Opus 5.5 on Medium effort
