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 xAI announced its latest artificial intelligence flagship model, Grok 3, on Monday. The company also announced Grok 3 mini, a scaled-back version, plus the addition of DeepSearch, a new tool that the company calls a next-generation search engine.
