As of recent developments, xAI, Elon Musk's AI startup, has been working on its own version of ChatGPT called Grok. This conversational AI model, equipped with internet browsing capabilities, can answer questions and engage in discussions, similar to ChatGPT and other text-generating models like Meta's Llama 2. Grok leverages a knowledge base to provide responses and can search the internet for up-to-date information on various topics. ​ However, Grok has its limitations. The AI is designed to refuse certain sensitive queries, indicating a degree of ethical filtering. Elon Musk has hinted that Grok's responses might incorporate a touch of humor, distinguishing it from other similar models. The system's ability to blend informative responses with a sense of humor could potentially offer users a unique and engaging conversational experience.
