A viral claim says Claude Opus 5 was left running for 24 hours and built a full game from scratch.
- The post says the game was created without external assets or code.
- It also claims the prompts, workflow, and code are included, making it useful as a concrete demo of long-horizon agentic coding.
- The tone suggests disbelief, which is exactly why the post reads more like a model-capability spectacle than a routine product update.
