"Elon Musk's xAI Unveils Grok 3: Revolutionizing AI with Colossus Supercomputer"
1min read Elon Musk's artificial intelligence company, xAI, has unveiled its latest AI model, Grok 3, on Tuesday, February 18, 2025. The release showcases the company's expanded computing infrastructure and claims improved performance across various benchmarks.
At the heart of Grok 3's development is Colossus, a supercomputer cluster utilizing 200,000 GPUs for AI training. The system was built in two phases, with initial training taking 122 days on 100,000 GPUs, followed by a 92-day scaling period to reach full capacity.
The model will be available to X Premium subscribers starting Tuesday in the United States, with access also provided through a separate subscription for web and app versions. XAI announced plans to introduce voice assistance features in the coming weeks.
During a live demonstration streamed on X, Musk expressed enthusiasm about the new model's capabilities. "We're very excited to present Grok 3, which is, we think, an order of magnitude more capable than Grok 2 in a very short period of time," he said.
Early testing results show promising performance. The base model topped charts in math (AIME), science (GPOA), and coding (LCB) tests. A specialized version called Reasoning Beta achieved 93% on the AIME 2025 benchmark, surpassing competing models that scored below 87%.
The company revealed that an early version of Grok 3, codenamed "Chocolate," received the highest ratings on Chatbot Arena, a platform where users evaluate AI models without knowing their identity. This blind testing approach helps prevent potential bias in evaluation.
XAI introduced a new feature called DeepSearch, described as a "next generation search engine." The tool is designed to search the web and generate comprehensive reports on various topics, similar to existing offerings from other AI companies.
The development team demonstrated Grok 3's abilities in solving physics problems and writing game code. They also announced plans for an AI gaming studio that will allow developers to create games powered by the new model.
Some early users have shared positive experiences. Computer scientist Lex Friedman praised the model's capabilities, while X user Penny2x demonstrated Grok 3's ability to create a 2D platformer game through
