The post adds cost and token stats to the earlier atomic-agent demo and links the GitHub repo.
- The test compared Kimi K3 and Claude Fable 5 on the same prompt set for building three 3D arcade classics.
- Kimi K3 ran locally on 8× B300, produced about 237K tokens, and incurred $0 in API spend.
- The author says Kimi’s Snake scene was the best of the six outputs, with soft shadows, dust, and self-checking game logic; its maze also regenerated on restart with a live minimap and ghost tracking.
- The linked project, atomic-agent, is positioned as a local-first AI agent with long context, proper tool calling, private on-device execution, memory/skills docs, and eval folders.
