OpenAI just dropped a new blog post defending itself against Musk that outlines some new text messages between cofounders Ilya Sutskever, Greg Brockman, Sam Altman, Elon Musk, and former board member Shivon Zilis.

The artificial intelligence start-up argues that Mr. Musk is trying to hamstring its business as he builds a rival company.

Meta says that Musk and his co-plaintiff Shivon Zilis are 'qualified and well-positioned to represent the interests of Californians in this matter.'
