Translated data: OpenAI's nonprofit division revealed in its latest tax documents that its net income was only $45,000 last year, despite the strong performance of its profitable business. Microsoft invested $10 billion for a 49% stake, and the valuation of the profit-making department could be as high as $90 billion. The company's structure has sparked controversy, with private investors committing billions of dollars in investment. Unlike other nonprofit organizations, OpenAI accepts venture capital.
