xAI introduced Grok 4, its latest chatbot model, trained on the Colossus supercomputer for advanced, scientist-grade reasoning. This model offers stronger logical reasoning and text generation capabilities. A coding-focused variant, Grok 4 Code, is designed to write, debug, and explain code efficiently, similar to GitHub Copilot or GPT-4 Code Interpreter.
Multimodal and Voice Features
Grok 4 supports multimodal inputs, including text, images, and potentially video, addressing previous limitations and competing with OpenAI’s GPT-5o and Google’s Gemini 2.5 Pro. It also includes Grok 4 Voice, which features a natural, human-like voice with fewer interruptions.
Real-Time Web Access and Cultural Fluency
The model incorporates DeepSearch, enabling real-time web access by pulling live data from Musk’s X platform, allowing up-to-date results during chats without needing a separate browser tab. Grok 4 is also tuned for cultural fluency, understanding memes, slang, and humor with high accuracy, making it one of the most internet-savvy AI assistants.
Musk’s Claims and Development Progress
Elon Musk described Grok 4 as "smarter than all graduate students in all disciplines simultaneously," "better than PhD level in every subject," and expects it to discover new, useful technologies by next year. The xAI team skipped the Grok 3.5 version to highlight the significant leap forward with Grok 4 and maintain a competitive advantage.
