Elon Musk, CEO of Tesla, X, and SpaceX and a member of the Trump administration team, founded a startup called xAI to challenge OpenAI’s dominance of ChatGPT. While ChatGPT and other AI models are by far the most popular,

Grok 3, Elon Musk’s AI model, is here with advanced reasoning, real-time data access, and superior performance, competing with GPT-4.

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.
