John Schulman, a prominent figure in AI development and OpenAI co-founder, has departed from Anthropic just months after joining the rival AI company following Sam Altman’s temporary removal from OpenAI. Schulman’s departure from Anthropic marks another significant shift in the AI industry’s talent landscape. He had initially left OpenAI during the November 2023 leadership crisis when Sam Altman was briefly ousted as CEO. During that turbulent period, Schulman, along with other employees, had threatened to leave if the board didn’t resign. After Altman’s reinstatement, Schulman chose not to return to OpenAI and instead joined Anthropic, a competitor focused on developing safe and ethical AI systems. His tenure at Anthropic lasted only a few months, though the specific reasons for his departure remain unclear. This move highlights the ongoing volatility in the AI sector and the complex dynamics between major AI companies competing for top talent. Schulman’s contributions to the field include significant work on reinforcement learning and the development of key AI technologies. His brief stay at Anthropic and subsequent departure reflect the fluid nature of leadership and talent movement within the AI industry, particularly among companies at the forefront of artificial intelligence development.
