The four models that make up the Grok 3 family were trained on a considerable amount of synthetic data and are designed to self-correct by analysing inconsistencies.

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

Elon Musk’s xAI has introduced Grok-3, a next-generation AI chatbot designed to change the way people interact on social media. Integrated directly into X (formerly Twitter), Grok-3 is built to provide more intelligent,

Elon Musk's startup xAI announced the Grok 3 AI models, which he claims are “the smartest AI on Earth.” The company posted the launch event video on February 18, 2025, demonstrating the

On Tuesday, February 18, Elon Musk’s xAI launched its latest flagship AI model, Grok 3, with enhanced capabilities. Grok 3 is a significant upgrade to Musk's AI models, which have been developed as an alternative to similar models like OpenAI’s GPT-4 and Google’s Gemini.

During the Grok 3 announcement livestream on X, Elon Musk claimed the new model is 10 times more powerful and "an order of magnitude" more capable
