Grok 3 is "scary smart," according to Elon Musk, and is "an order of magnitude more powerful than Grok 2."

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.

Grok talked the talk, but it's no longer walking the walk. The xAI chatbot pulled no punches Sunday when AI expert Linus Ekenstam turned to X and asked the online tool, "Who is the biggest disinformation spreader on X?
