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.

Hours after Elon Musk’s AI company, xAI, unveiled the latest version of its AI model, Grok 3, X has significantly increased the cost of its top-tier Premium+ subscription plan. This plan, which provides users access to the latest AI model, now costs nearly $50 per month.

“This is it: The world’s smartest AI, Grok 3, now available for free (until our servers melt),” xAI wrote on X, the platform previously known as Twitter. “X Premium+ and SuperGrok users will have increased access to Grok 3, in addition to early access to advanced features like Voice Mode.”
