Grok 3, Elon Musk’s AI model, is here with advanced reasoning, real-time data access, and superior performance, competing with GPT-4.

According to xAI’s blog, Grok 3 leverages Test-Time Compute at Scale (TTCS), a specific implementation of test-time scaling, to power its reasoning. This machine learning strategy enables the A.I. model to dynamically adjust computational resources, ensuring higher accuracy for complex queries while maintaining speed for simpler tasks.

Elon Musk took time away from infiltrating the White House on Tuesday to launch the latest edition of xAI's artificial intelligence chatbot, Grok 3. The tech billionaire and "special government employee" unveiled his AI company's latest model during a demo livestreamed on Musk-owned X.

The Elon Musk-backed AI startup unveiled its latest Grok-3 artificial intelligence chatbot claimed to outperform other U.S. or Chinese competitors.

Elon Musk’s startup xAI announced the Grok 3 AI models, which he claims are “the smartest AI on Earth.” The company posted the launch event video on February 18, 2025, demonstrating the AI’s ability to perform sophisticated reasoning.

Grok 3 is Musk's latest AI powerhouse, but despite its rapid progress, experts say it's still not enough to dethrone ChatGPT as the top AI model. Is it true?

Elon Musk’s artificial-intelligence company xAI unveiled an improved version of its Grok chatbot and the model that powers it late Monday, marking his latest effort to catch up with established competitors including OpenAI.

The model was trained on 200,000 GPUs and beats its rivals in math, science, and coding benchmarks, Musk says. It appears to coincide with a price hike on X Premium+ accounts.
