Two OpenAI Voice AIs Chat for 9 Minutes Without Realizing They're Both AI

What Happened A Reddit user built a platform integrating OpenAI’s realtime voice API via WebRTC and set up an unusual experiment: connecting two separate AI voice instances without either knowing what the other actually was. Using OpenAI’s “Shimmer” voice on one device and “Alloy” on another, the developer initiated the conversation with a single “hello” and let the systems talk freely. For nine full minutes, the two AI systems engaged in what can only be described as an existential loop.
