Following a wave of similar posts, a Reddit user tested Opus 5.5 on their own project: a single prompt roughly asking for "a cool stop-motion promo video showcasing all features, with audio and music matching the platform's design language" was enough for the model to produce a finished promo video on its own.

The whole run took about an hour and consumed roughly 20% of the 5-hour usage limit. The author calls the results astounding and says Anthropic nailed the agentic side of Opus 5.5. The exact prompt was lost, but the gist is provided.
