Musk-led group makes 97.4bn bid for ChatGPT maker OpenAI

OpenAI is widely credited with helping bring artificial intelligence tools into the mainstream and sparking huge investment in the sector. Musk and Altman co-founded the start-up in 2015 as a non-profit company, but the relationship has soured since the Tesla and X boss departed the firm in 2018. Altman is said to be restructuring the company to become a for-profit entity, stripping it of its non-profit board - a move Musk argues means the company has abandoned its founding mission of developing AI for the benefit of humanity. But OpenAI argues its transition into a for-profit firm is required to secure the money needed for developing the best artificial intelligence models. "It's time for OpenAI to return to the open-source, safety-focused force for good it once was. We will make sure that happens," Musk said in a statement.
