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.

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 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.
