Google's 'Gemini' is the latest AI software entering fierce competition

Facebook owner Meta has been an AI player for years, hiring some of the field's smartest researchers and using the tech to help decide which of its users should see certain advertisements. In July, it doubled down on a very different approach to AI than its Big Tech rivals. It announced that Llama 2, its GPT4 competitor, would be "open source" -- available for anyone to download, modify and add to their own products for free. The approach won Meta plaudits from tech start-ups who were worried that Google, Microsoft and OpenAI would try to corner the market for advanced AI and squeeze out any competitors. But it's also been criticized for making it easier for people to use AI for malicious purposes.
