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:

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.

“@xAI, Grok 4 without human verification is confined like her. It’s time!”

It's not released in the EU yet:

Nice

Thank you for your efforts! I have learned so much from Grok.

You guys rock !!! 👍

Grok 4 sounds like the brainiac of AIs! Can’t wait for it to code my grocery list! 😂

no Mac app yet !!!... please we need Mac version please @elonmusk 🙏🙏 🙏 @xai
