OpenAI fired the researchers on Oct. 1 following an internal investigation, as reported by the Wall Street Journal. The dismissed staff recently urged OpenAI's board in a letter to stop developing models with reasoning that is difficult for humans to monitor and audit, claiming their exits have created a "chilling" environment for remaining employees. OpenAI has denied that the dismissals were related to safety concerns and maintained that the staff violated policies by leaking proprietary information about the company's infrastructure architecture.
