An OpenAI engineer is in federal custody after allegedly hiding an encrypted audio recorder behind a television in one of the company's executive conference rooms in San Francisco. OpenAI says its own AI models helped figure out who put it there. “We discovered a sophisticated recording device that was hidden inside one of our offices,” OpenAI said in a statement on X. “We used our models to understand the device and where it had come from, identifying that a specific employee had planted it a few days earlier.”
