The eagerly anticipated Grok-4 has launched, exceeding expectations despite a delayed stream. xAI’s Elon Musk hailed it as “PhD-level in everything,” stating it achieves perfect scores on tests like the SAT and excels across various fields, including humanities, math, and engineering. Grok-4’s reasoning is likened to human cognition, solving previously unseen problems and outperforming graduate students in multiple disciplines.
Two versions are available: Grok 4 and Grok 4 Heavy, the latter utilizing a multi-agent system for enhanced problem-solving. Grok-4 leads on the ARC-AGI-2 benchmark with a 15.9% accuracy rate, significantly outperforming competitor models. It unlocks practical applications across fields like robotics, biomedical research, and finance, showcasing robust real-time decision-making.
Enhanced voice capabilities also offer a variety of natural vocal options. Future developments aim to improve multimodal performance and introduce video generation capabilities, reinforcing Grok-4’s status as a groundbreaking AI tool.
