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.

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 AI company, xAI, released its latest flagship AI model, Grok 3, on Monday, along with new capabilities in the Grok app for iOS and the web.

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 four models that make up the Grok 3 family were trained on a considerable amount of synthetic data and are designed to self-correct by analysing inconsistencies.

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 and xAI have developed a new artificial intelligence system that can create classic video games in less than 3 minutes.

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.

Elon Musk debuted his Grok 3 artificial intelligence chatbot, a potential competitor to ChaptGPT and China's DeepSeek in the booming technology space. CBS MoneyWatch correspondent Kelly O'Grady has more.

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.
