Microsoft and OpenAI's collaboration faces tension over access to artificial general intelligence (AGI). OpenAI may restrict Microsoft's access to new models upon declaring AGI, a milestone OpenAI CEO Sam Altman sees as imminent. Microsoft CEO Satya Nadella rebuffs this, calling it "nonsensical benchmark hacking." The partnership is further complicated as OpenAI seeks to become a for-profit entity, putting billions on the line and raising concerns over intellectual property and revenue-sharing.
