Dice-roll

Dice Roll was created during a hackathon organized by OpenAI and 42AI. The brief was simple: give Codex a capability it didn't already have.

Our team started with one observation : AI systems can generate pseudo-random numbers, but they are incapable of creating pure randomness. We decided to give Codex the ability to do so.

Over the course of a single day, we designed and built Dice Roll—earning third place and a bronze medal in the competition.

Dice Roll gives AI systems access to randomness generated in the physical world.

When Codex calls the tool, a real six-sided die is rolled in front of a camera. The result is visually identified and returned to the AI, allowing it to continue its task using the number that was physically produced.

No artificially generated number. Just a real die rolling in the real world.

The idea is intentionally a little absurd—and we fully embraced that. Its simplicity made the concept immediately understandable while demonstrating how an AI agent could interact with an event outside its digital environment.
