One-time economic leader the Harvard professor is exiting the governing body at the ChatGPT creator, just days after a series of emails between him and late convicted sex offender the accused trafficker became widely known.
Summers commented in a statement that he was "appreciative for the chance to have participated, excited about the promise of the organization, and eagerly await observing their advancement".
The former Harvard president, who formerly headed the Ivy League institution, declared on earlier this week that he would be withdrawing from public roles due to his relationship with the convicted sex offender.
The newly public communications revealed that the economist communicated with the financier until the eve of the financier's 2019 apprehension for accused sex trafficking of young people.
In additional comments, the AI firm expressed it accepted Summers' decision to resign.
"We value his significant contributions and the insight he offered to the Board," OpenAI remarked.
This announcement follows after both chambers of the legislative branch decided on Tuesday to endorse a legislation that would require the US justice department to make public its documents on Epstein.
The legislation will then head to the administration of US President Donald Trump for endorsement. He has stated he plans to sign the legislation, after reversing his position on the matter following pushback from his base.
A batch of Epstein-connected correspondence released by the House Oversight Committee days ago included several high-profile figures in the billionaire's former circle, without implying any illegal behavior by those people.
The messages revealed that Summers and the financier often met for meals, with he often trying to connect the academic to influential global figures.
After the correspondence were made available with the wider community, Summers stated he assumed "total ownership for my misguided choice to maintain corresponding with Jeffrey Epstein".
He continued that he hoped "to restore faith and repair bonds with the individuals closest to me".
The professor served in senior posts under Democratic administrations; acting as treasury secretary under Bill Clinton, and as head of the National Economic Council under President Obama.
He led the institution from five years and is still a professor there. When announcing his departure from public commitments previously on Monday, he indicated he would maintain his educational duties.
Following the economist's announcement on Monday, the Center for American Progress, a liberal research organization in DC where the professor was a senior fellow, verified that Summers was ceased to be affiliated with the organization.
Summers entered the directorate of the AI company, which creates the AI chatbot, in 2023 - following a failed attempt to replace its chief executive OpenAI's head.
