'Earthquake' at ChatGPT developer as senior staff quit after sacking of boss Sam Altman

The crisis at artificial intelligence firm OpenAI deepened this weekend amid a reported exodus of senior staff in the wake of boss Sam Altman's mystery firing. OpenAI, the company behind the ChatGPT bot, abruptly ousted Altman on Friday for allegedly misleading the board. In a statement, it said it had lost confidence in its 38-year-old co-founder after "a deliberative review process" concluded he had not been "consistently candid in his communications", without specifying how. Shortly afterwards, Greg Brockman, the company's president, announced he had resigned. "Sam and I are shocked and saddened by what the board did today… We too are still trying to figure out exactly what happened," he wrote on X.
