Elon Musk's artificial intelligence startup xAI will be integrated into his social media platform X and also be available as a standalone app, he said on Sunday in a post. The billionaire also said xAI released its first AI model, a bot named Grok, after making it available to all X Premium subscribers on Friday. The startup aims to create AI tools that'assist humanity in its quest for understanding and knowledge' and that Grok has been designed to answer questions with a bit of wit. Musk who has criticized Big Tech's AI efforts as ridden with censorship, in July launched xAI, calling it a "maximum truth-seeking AI" that tries to understand the nature of the universe to rival Google's Bard and Microsoft's Bing AI. "Grok has real-time access to info via the X platform, which is a massive advantage over other models," Musk added. X, the social media firm formerly known as Twitter which Musk owns, is separate from xAI, but the companies work closely together.
