- A user shows another Three.js video game built with Opus 5 and ultracode mode from a single prompt.
- The referenced example was a Homeworld-style space RTS generated with Opus 5 workflow.
- The quoted run used 68.6k input tokens, 4.6M output tokens, 837.2M cache reads, 13.6M cache writes, and cost $632.65.
- The post emphasizes that, despite minor gameplay issues, watching the model “cook” a playable game is impressive.
