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.

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.
