Facebook parent Meta and IBM on Tuesday launched a new group called the AI Alliance advocating for an "open-science" approach to AI development that puts them at odds with rivals Google, Microsoft and ChatGPT-maker OpenAI. These two diverging camps – the open and the closed – disagree about whether to build AI in a way that makes the underlying technology widely accessible. Safety is at the heart of the debate, but so is who gets to profit from AI's advances. Open advocates favor an approach that is "not proprietary and closed", said Darío Gil, a senior vice-president at IBM who directs its research division. "So it's not like a thing that is locked in a barrel and no one knows what they are."
