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.

The lead engineer at xAI blames an employee who 'hasn’t fully absorbed xAI's culture yet' for the glitch. Grok 3 now says Elon Musk is the biggest spreader of misinformation on X.
