Code-generated AI videos: 513 viral Opus 5.5 cases and prompts open-sourced, Step 5 Preview at 1/8 cost

- Core idea: code-generated motion videos are underrated — pixel-perfect text/layout and millisecond-level timing control, and SOTA models aren't required if prompts are detailed enough.
- Author's practice: switching Claude Code to StepFun's step 5 preview (1/8 the cost of Opus 5), the author produced demos like a 3D miniature town's 24-hour cycle, Chinese kinetic typography, single-shape UI transitions, and green-screen dance × magazine layouts. One run can operate for hours, making 200+ tool calls covering code, music, rendering, and QA.
- Workflow split: code handles camera, layout, and rhythm; image models handle static assets; video models handle complex local motion.
- Open resource: awesome-opus5-5-videos (3.6k stars) collects 513 viral Opus 5.5 videos with full prompts; refine prompts to cover duration, beats, per-shot content, and acceptance criteria.
- Note: step 5 preview is on OpenRouter with 1M context; open weights due Oct 15. Already commercially viable for brand motion graphics, product demos, and batch short-video production.
