In May 2023, British Prime Minister Rishi Sunak convened a significant meeting with key figures in the artificial intelligence (AI) landscape, including Demis Hassabis, CEO of DeepMind; Dario Amodei, CEO of Anthropic; and Sam Altman, CEO of OpenAI.

OpenAI, established in 2015, initially garnered substantial support from a consortium including Sam Altman, Greg Brockman, Elon Musk, Jessica Livingston, Peter Thiel, Microsoft, Amazon Web Services, Infosys, and YC Research, securing an initial funding of $1 billion. Notably, Altman transitioned to full-time leadership as CEO in March 2019, a move coinciding with a notable fundraising effort that yielded an additional $1 billion from Microsoft by the summer of 2019.

In a pivotal moment in May 2023, Altman testified before the United States Senate Judiciary Subcommittee on Privacy, Technology, and the Law, addressing critical concerns surrounding AI oversight. Subsequently, he embarked on a comprehensive world tour, engaging with leaders and diplomats from 22 countries, including notable figures such as British Prime Minister Rishi Sunak, French President Emmanuel Macron, and German Chancellor Olaf Scholz.

However, the trajectory of OpenAI experienced a significant shake-up in November 2023, marked by the removal of Altman as CEO and Greg Brockman from the board. The decision, announced by the board comprising notable figures such as researcher Helen Toner and Quora CEO Adam D’Angelo, cited communication discrepancies on Altman’s part. Brockman resigned from his role as President of OpenAI in response to the announcement.

Subsequent negotiations between Altman and the board ensued, with Microsoft CEO Satya Nadella announcing Altman’s recruitment to spearhead a new advanced AI research team at Microsoft on November 20. In a show of solidarity, OpenAI employees, including co-founder and chief scientist Ilya Sutskyver, rallied behind Altman, issuing an open letter threatening mass resignation unless the board resigned and Altman was reinstated.

This collective action prompted an “agreement in principle” for Altman and Brockman to return to their respective leadership roles at OpenAI, signaling a pivotal moment in the organization’s governance structure.
