OpenAI's former chief technology officer, Mira Murati, announced her departure from the ChatGPT maker on Wednesday, followed by the departure of two other top executives of artificial intelligence firm.

According to CNN, Murati stated in a written statement that she made the "difficult decision" to step away from Sam Altman's tech firm "to create the time and space to do my own exploration."

Last year, Murati also served as the ChatGPT maker's interim CEO for a brief period as the firm experienced unprecedented changes in its leadership.

Following Murati's announcement, Altman took to social media and revealed that two other top executives were also leaving the company.

The decisions by Murati, as well as OpenAI’s Chief Research Officer Bob McGrew and another research leader, Barret Zoph, were made "independently of each other and amicably," Altman said in a note to employees he shared on social media.

Murati, McGrew, and Zoph mark the latest high-profile departures from the San Francisco-based tech firm after the company's co-founder, John Schulman, left in August to join its rival, Anthropic, which was founded in 2021 by a group of ex-OpenAI leaders.

Additionally, the company's president and co-founder, Greg Brockman said in August that he was "taking a sabbatical" through the end of the year.

Before him, another co-founder, Ilya Sutskever, who led a team focused on AI safety, left OpenAI in May to start his own AI company.
