xAI, the Elon Musk-owned artificial intelligence startup, has launched an AI-powered assistant called 'Grok' to rival OpenAI's chatbot ChatGPT.

The chatbot is powered by a large language model called Grok-1, which has been trained on a massive dataset of text and code to perform a variety of tasks, including answering questions, generating creative text formats, translating languages, and writing different kinds of creative content. This is not dissimilar to the functional capabilities of other chatbots like OpenAI's ChatGPT and Google's Bard.

This comes almost a year after Musk announced that he will launch a maximum truth-seeking AI which will make an effort to understand how the universe works. Notably, the billionaire has remained critical of other AI efforts made by big tech firms due to their design to give politically correct responses

Meanwhile, Grok which is modelled after the fictional supercomputer from The Hitchhiker's Guide to the Galaxy, is designed to answer questions with a bit of humour and sarcasm.

Musk has said that while Grok is still under development, he believes that it has the potential to be "one of the most powerful AI tools ever created." He has also said that Grok will eventually be integrated into his social media platform, X (formerly known as Twitter).

The model has been made available to a limited number of users in the U.S. as a prototype and is set to add more “new capabilities and features” as it rolls out to more users in the coming months.

With ChatGPT being the most prominent rival, Grok is entering a competitive market. However, Musk believes that Grok has several advantages over ChatGPT, including its access to real-time data from the X platform and its ability to answer "spicy" questions that are rejected by most other AI systems.

It is still too early to say whether Grok will be a success, but it is clear that Musk is serious about making xAI a major player in the AI industry. With Musk's backing and the company's access to resources, Grok has the potential to become a major force in the chatbot market.
