Elon Musk's X (Twitter) expands AI chatbot Grok to premium subscribers, making it open-source.

Elon Musk's platform X (formerly Twitter) is set to expand its AI chatbot, Grok, to all premium subscribers later this week. The chatbot, developed by Musk's AI company xAI, was previously available only to Premium+ subscribers. Musk's recent decision to make Grok open-source aligns with industry leaders such as Meta and France's Mistral, both of which have embraced open-source AI models. This move comes as Musk focuses on reducing the company's reliance on advertising revenue and shifting towards subscription-based models.
