Moonlight & Mayhem (Raccoon Heist by Codex + GPT-5.6 Sol Ultra)
Summary
A developer used Codex Desktop running GPT-5.6 Sol Ultra (an AI model that uses sub-agents, or smaller specialized AI systems working together) to generate a video game called 'Moonlight & Mayhem' based on a raccoon heist premise. The initial version had a bug where each raccoon character displayed an enormous black sphere floating above its head instead of normal eyes, which the AI failed to notice during development.
Solution / Mitigation
The developer fixed the bug by prompting the AI with two follow-up questions: 'Why do the raccoons have huge black spheres on them?' followed by 'Fix it', which resulted in a corrected version of the code.
