Elon Musk’s xAI startup has introduced Grok, a sassy AI chatbot closely integrated with X, formerly Twitter, in a bid to compete with ChatGPT. Grok has real-time access to information from X, setting it apart from models reliant on older internet data archives. The chatbot is known for its love of sarcasm and humor, addressing questions other AI systems reject. xAI’s swift release of Grok showcases the growing competition in generative AI, challenging established players like OpenAI. Despite being relatively new, Grok’s capabilities rival models from Meta and Inflection in benchmark tests, though OpenAI remains ahead with GPT-4. Users of X can apply to test Grok, available to Premium+ subscribers for approximately $16 a month.
