Elon Musk threatens to sue Microsoft over Twitter data use for A.I.

Elon Musk has threatened to take legal action against Microsoft over claims that the company "trained illegally using Twitter data." The threat appears to be over OpenAI using Twitter data to train the large language model behind products like ChatGPT. Microsoft recently invested in OpenAI, which is building AI into tools like Bing, Edge, and Microsoft 365. Microsoft's advertising platform announced it would stop supporting Twitter, reportedly due to Twitter's changes requiring payment to access its API. Twitter's new pricing system has already led some smaller developers to abandon the platform.
