Microsoft in talks to invest $10 bln in ChatGPT-owner OpenAI, Semafor reportsJan 10 (Reuters) - Microsoft Corp (MSFT.O) is in talks to invest $10 billion in ChatGPT-owner OpenAI as part of funding that will value the firm at $29 billion, Semafor reported on Monday, citing people familiar with the matter.The news underscores rising interest in the artificial intelligence company, whose chatbot has dazzled amateurs and industry experts with its ability to spit out haikus, debug code and answer questions while imitating human speech.Microsoft's cloud services arm also provides the computing power needed by the AI firm.OpenAI charges developers licensing its technology about a penny or a little more to generate 20,000 words of text, and about 2 cents to create an image from a written prompt.A Wall Street Journal report said last week OpenAI was in talks to sell existing shares at a roughly $29 billion valuation in a tender offer that would attract investment of at least $300 million."
