The Elon Musk-backed AI startup unveiled its latest Grok-3 artificial intelligence chatbot claimed to outperform other U.S. or Chinese competitors.

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 took time away from infiltrating the White House on Tuesday to launch the latest edition of xAI's artificial intelligence chatbot, Grok 3. The tech billionaire and "special government employee" unveiled his AI company's latest model during a demo livestreamed on Musk-owned X.

Elon Musk announced Grok 2 will soon be upgraded to Grok 3, enhancing AI interpretation on the platform. The new model, launched by xAI, boasts ten times the computing power of Grok 2.

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?

The model was trained on 200,000 GPUs and beats its rivals in math, science, and coding benchmarks, Musk says. It appears to coincide with a price hike on X Premium+ accounts.

Billionaire Elon Musk said on Saturday that his xAI's artificial intelligence chatbot and ChatGPT challenger Grok 3 would be released with a live demo at 8 p.m. Pacific time on Monday (0400 GMT on Tuesday).

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 AI’s ability to perform sophisticated reasoning.

Elon Musk has announced that Grok 3, the latest AI model from xAI, will be available for free temporarily. The advanced model promises improved reasoning and language comprehension. Users can access it via X,
