Elon Musk made good on that promise early on by sharing the source code that powers the Grok chatbot. A few days ago, Tesla and SpaceX CEO released a statement with the following content. “@xAI will open source Grok this week.”

Late last month, Musk sued OpenAI and Altman, arguing that the ChatGPT maker’s multi-year, multibillion-dollar partnership with Microsoft betrayed its core desire to benefit humanity. The lawsuit alleges breach of contract, duty and unfair business practices. The billionaire also wanted OpenAI to make its research and technology public.

OpenAI, which Musk founded with Altman in 2015, responded to Musk’s lawsuit earlier this month with a blog post that included screenshots of emails Musk received during his time at the company. They cited support for turning OpenAI into a commercial company and trying to merge with Tesla to compete with Google’s AI efforts.
