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'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’s xAI unveiled Grok-3 on Tuesday, announcing that the new artificial intelligence model has “more than 10 times” the compute power of its predecessor. xAI said its latest flagship outperforms OpenAI’s GPT-4o, Google’s Gemini, and DeepSeek’s V3 models in early testing, and now features “advanced reasoning” capabilities.
