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 and xAI have developed a new artificial intelligence system that can create classic video games in less than 3 minutes.

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 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.

With Grok-3, xAI aims to outsmart the competition. We pit it against GPT-4o, Gemini, DeepSeek, and Claude 3.5 Sonnet to see if Elon Musk’s latest creation lives up to the hype.

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.

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.

Elon Musk’s AI company, xAI, released its latest flagship AI model, Grok 3, late Monday night, along with new capabilities in the Grok apps for iOS and the web. Grok, xAI’s answer to models like OpenAI’s GPT-4o and Google’s Gemini,
