Elon Musk’s xAI has made an older version of its AI model Grok — specifically, the model weights used to shape Grok 2.5 —  available on the open source platform Hugging Face.

Elon Musk threatened to sue Apple for favoring ChatGPT over Grok in the App Store — and now he has. On Monday, Musk's AI company xAI officially filed a lawsuit against Apple as well as ChatGPT creator OpenAI over the two companies' business partnership.

Elon Musk on Monday targeted Apple and OpenAI in an antitrust lawsuit alleging that the iPhone maker and the ChatGPT maker are teaming up to thwart competition in artificial intelligence. The 61-page complaint filed in Texas federal court follows through on a threat that Musk made two weeks ago when he accused Apple of unfairly favoring OpenAI and ChatGPT in the iPhone's app store rankings for top AI apps.
