The Signal chats that cost three OpenAI researchers their jobs

OpenAI dismissed three AI security researchers after suspecting they leaked sensitive information. The company found that some had used disappearing messages on Signal. The firings occurred amid concerns about AI oversight and control. OpenAI stated the dismissals were due to policy violations, while the researchers claimed they were promoting industry collaboration on security. They expressed worries about new AI architectures that could complicate oversight. Other AI labs are also debating information sharing with external security researchers. OpenAI recently collaborated with METR and Redwood Research to evaluate security systems, but tensions arose over access to proprietary information.
