OpenAI has completed its "recapitalization", with a non-profit, the OpenAI Foundation, controlling a new for-profit business, OpenAI Group PBC.
Microsoft owns approximately 27 percent of OpenAI Group PBC, valued at about $135 billion, given OpenAI's recent valuation.
"We've signed a new definitive agreement with OpenAI that builds on our foundation, strengthens our partnership, and sets the stage for long-term success for both organizations,"
Microsoft remains OpenAI's frontier model partner, with exclusive IP rights and Azure API exclusivity until Artificial General Intelligence (AGI) is achieved.
