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 to break down tasks) to generate a complete video game called "Moonlight & Mayhem" from a text prompt, and it produced a better result than Claude Fable 5 had generated previously. The AI-created game had a bug where raccoon characters displayed giant black spheres as eyes, which the developer fixed by asking the AI directly to identify and correct the problem through follow-up prompts.
Solution / Mitigation
The developer fixed the eyeball bug by prompting the AI with: "Why do the raccoons have huge black spheres on them?" followed by "Fix it", which resulted in a corrected version of the code.
