Opus 5.5 is good at explainer videos

Paste a URL or describe the product. Opus 5.5 writes the film and a serverless agent renders it. About four minutes and roughly 100k tokens per video.

Each one is a single run: a URL or a prompt in, an MP4 out. No edits.

“make a modern slick and punchy video for a modern startup that works on inference”

The whole product is one agent file, three tools, and this form. OpenComputer runs the agent, the microVM it renders in, the model gateway, and the session API the page polls.
