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.

AI on Monday unveiled its updated Grok 3 artificial intelligence model, as the Elon Musk-led startup works to keep pace with the reasoning and search capabilities in competitors’ models.

Musk described Grok 3 as the "smartest AI on Earth," launching the AI via his social media platform X (formerly Twitter). Newsweek contacted OpenAI and DeepSeek for a response to
