Elon Musk announced on Thursday that Grok, a rival to ChatGPT, is being made available to Premium+ users of social networking platform X by his artificial intelligence (AI) business, xAI.

Without providing any additional information about the launch, he made the announcement in a post on X. He had stated last month that subscribers would be able to use Grok as soon as it exited early beta testing.

The entrepreneur has emphasized lowering the company’s reliance on advertising and has shifted his focus to improving subscriptions and making them more appealing as more advertisers leave the microblogging platform.

He even intends to turn X into a “super app”, offering a range of services to its subscribers from messaging and social networking to peer-to-peer payments.

Musk launched xAI in July in a response to Big Tech’s AI efforts, which he has criticized for excessive censorship and a lack of adequate safety measures.

Large tech companies including Microsoft (MSFT.O) and Alphabet’s Google are racing to launch AI-powered products after OpenAI’s chatbot ChatGPT caught the imagination of businesses and users globally.
