OpenAI CEO Sam Altman’s sister, Ann Altman, filed a lawsuit alleging that he regularly sexually assaulted her between 1997 and 2006.
The lawsuit, filed Jan. 6 in the US District Court for the Eastern District of Missouri, alleges the abuse began when she was three and Mr. Altman was 12.
In the joint statement on Xwith his mother and two brothers, Mr. Altman denied the allegations, saying “all of these allegations are completely false.”
“Caring for a family member facing mental health challenges is incredibly difficult,” the statement added.
“This situation is causing tremendous pain to our entire family.”
In the filing, seen by the BBC, Ms Altman said the abuse, which took place over many years, included rape.
The lawsuit adds that the last instance of alleged abuse occurred when Mr. Altman was an adult, but she was still a minor.
The lawsuit sought a jury trial and damages in excess of $US75,000 ($60,100).
Ms. Altman had previously made similar allegations against her brother on social media platforms such as X.
Mr. Altman is one of the most prominent figures in the world of technology.
In late 2022, OpenAi launched the ChatGPT generative artificial intelligence (AI) chatbot.
