AI assistant by Anthropic with advanced reasoning and long context windows

Grok, developed by Elon Musk's xAI company, brings a unique personality to the AI chatbot space. Named after the term from Robert Heinlein's science fiction, meaning to understand something deeply and intuitively, Grok is designed to be more than just an information retrieval tool. What sets Grok apart is its real-time access to X (formerly Twitter), giving it current information about trending topics, breaking news, and public sentiment. This makes Grok particularly valuable for understanding current events, social trends, and public discussions. The AI is programmed with a sense of humor and personality - it can be witty, slightly irreverent, and engaging in ways that more conservative AI assistants avoid. Grok is built on xAI's own large language models and is being continuously improved based on user interactions. Currently, Grok is available exclusively to X Premium+ subscribers, making it part of the broader X ecosystem. The AI can help with research, answer questions, provide summaries of X discussions, and even engage in creative writing. xAI positions Grok as an AI that seeks to answer "spicy questions" that other AIs might refuse, though it still maintains safety guidelines.
