OpenAI’s chief communications officer, Hannah Wong, announced internally on Monday that she is leaving the company in January, WIRED has learned. In a statement to WIRED, OpenAI spokesperson Kayla Wood confirmed the departure.

“Hannah has played a defining role in shaping how people understand OpenAI and the work we do,” said CEO Sam Altman and CEO of applications Fidji Simo in a joint statement. “She has an extraordinary ability to bring clarity to complex ideas, and to do it with care and grace. We’re deeply grateful for her leadership and partnership these last five years, and we wish her the very best.”

Wong joined OpenAI in 2021 when it was a relatively small research lab and has led the company’s communications team as ChatGPT has grown into one of the world’s largest consumer products. She was considered instrumental in leading the company through the PR crisis that was Altman’s brief ouster and rehiring in 2023—a period the company internally calls “the blip.” Wong assumed the chief communications officer role in August 2024 and has expanded the company’s communications team since then.

In a drafted LinkedIn post shared with WIRED, Wong said that OpenAI’s VP of communications, Lindsey Held, will lead the company’s communications team until a new chief communications officer is hired. OpenAI’s chief marketing officer, Kate Rouch, is leading the search for Wong’s replacement.

“These years have been intense and deeply formative,” said Wong in the LinkedIn post. “I’m grateful I got to help tell OpenAI’s story, introduce ChatGPT and other incredible products to the world, and share more about the people forging the path to AGI during an extraordinary moment of growth and momentum.”

Wong says she looks forward to spending more time with her husband and kids as she figures out the next chapter in her career.

Update: 12/15/2025, 7:30 pm EDT: WIRED has clarified Kate Rouch’s title.
