Feb 19, 2025 - cnet.com
xAI, founded by Elon Musk, has unveiled its latest AI model, Grok 3, which Musk describes as "scary smart" and significantly more powerful than its predecessor, Grok 2. Grok 3 was trained on 200,000 Nvidia H100 GPUs, double the number used for Grok 2, and boasts 15 times more computing power. The model was trained on diverse data sources, including user posts and court documents. Alongside Grok 3, xAI introduced Grok 3 mini and DeepSearch, a next-generation search engine. Grok 3 is initially available to X Premium Plus members, with a broader rollout planned through a subscription service called SuperGrok.

DeepSearch, part of Grok 3's capabilities, allows users to ask questions and receive detailed answers, showcasing the model's reasoning process. During a demonstration, DeepSearch used multiple sources to provide comprehensive responses, highlighting its advanced reasoning capabilities. Despite Musk's claims of Grok 3's superior performance, there are no independent tests available yet. Grok 3 faces competition from AI models by OpenAI, Google, and Anthropic, all of which are advancing their AI technologies in 2025.
