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 AI company, xAI, released its latest flagship AI model, Grok 3, on Monday, along with new capabilities in the Grok app for iOS and the web.

Elon Musk’s xAI unveiled Grok-3 on Tuesday, announcing that the new artificial intelligence model has “more than 10 times” the compute power of its predecessor. xAI said its latest flagship outperforms OpenAI’s GPT-4o, Google’s Gemini, and DeepSeek’s V3 models in early testing, and now features “advanced reasoning” capabilities.

Elon Musk’s artificial-intelligence company xAI unveiled an improved version of its Grok chatbot and the model that powers it late Monday, marking his latest effort to catch up with established competitors including OpenAI.

Grok 3, Elon Musk’s AI model, is here with advanced reasoning, real-time data access, and superior performance, competing with GPT-4.

Elon Musk revealed his new chatbot, Grok 3, on Monday. Maria Curi, tech policy reporter for Axios, joined CBS News to discuss the new product.

Grok 3 is Musk's latest AI powerhouse, but despite its rapid progress, experts say it's still not enough to dethrone ChatGPT as the top AI model. Is it true?

Elon Musk’s OpenAI rival, xAI, says it’s investigating why its Grok AI chatbot suggested that both President Donald Trump and Musk deserve the death penalty. xAI has already patched the issue and Grok will no longer give suggestions for who it thinks should receive capital punishment.

The world's richest man Elon Musk's chatbot Grok was asked which US citizen should get the death penalty - it says Elon and Donald Trump.
