We just unveiled Grok 4, the world’s smartest artificial intelligence. 🧵 Grok 4 outperforms all other models on the ARC-AGI benchmark, scoring 15.9% - nearly double that of the next best model - and establishing itself as the most intelligent AI to date.

Humanity's Last Exam (HLE) is a rigorous intelligence benchmark featuring over 2500 problems crafted by experts in mathematics, natural sciences, engineering, and humanities. Most models score single-digit accuracy. Grok 4 and Grok 4 Heavy outperform all others.

Grok 4 exhibits superhuman reasoning capabilities, surpassing the intelligence of nearly all graduate students across every discipline simultaneously. We anticipate Grok will uncover new physics and technology within 1-2 years.

Grok 4 Heavy utilizes a multi-agent system, deploying several independent agents in parallel to process tasks, then cross-evaluating their outputs for the most accurate and effective results.

We’ve also introduced new, hyper-realistic voices with rich emotions with Grok 4.

And, you can now use Grok 4 to make advanced searches on 𝕏.

We’re diligently improving Grok, building a specialized coding model, improving multi modal capabilities, and developing a strong model for video generation and understanding. Grok on Web: Grok on iOS: Grok on Android: Grok API console:
