Wed Feb 19 16:12:37 UTC 2025: ## Elon Musk’s xAI Unveils Grok 3: A Powerful New AI Challenger

**SAN FRANCISCO** – Elon Musk’s xAI has launched Grok 3, a new artificial intelligence model boasting significantly enhanced capabilities designed to rival industry leaders like OpenAI, Google, and DeepSeek. Grok 3 features improved performance in mathematics, science, and coding, incorporating “Think Mode” for step-by-step reasoning and “Big Brain Mode” for tackling complex problems using increased computational resources.

Musk claims Grok 3 is “the smartest AI on earth,” leveraging ten times the computational power of its predecessor. Trained using 200,000 Nvidia H100 GPUs (estimated cost: $6-$8 billion), Grok 3’s development involved a two-stage process totaling 214 days. This massive computational power allows for faster, more accurate processing of vast datasets. Key enhancements include synthetic dataset capabilities, self-correction functions, and reinforcement learning mechanisms.

Access to Grok 3 is available via a subscription to X Premium+ or the higher-tier SuperGrok ($30/month) on Musk’s X platform (formerly Twitter). This pricing model, which also saw a near-doubling of X Premium+ costs, is justified by Musk as providing wider access to powerful AI tools. Grok 2, the previous version, remains free and will be open-sourced.

While xAI highlights Grok 3’s superior benchmark performance, user feedback is mixed. Some users praise its code generation and insightful responses, while others express concerns about response length, clarity, and overall consistency compared to competitors like OpenAI’s GPT-4. Independent benchmark tests are expected to further clarify Grok 3’s position in the competitive AI landscape. Despite initial uncertainties, experts suggest Grok 3 has the potential to become a major player in the field. The launch also includes “Deep Search,” a next-generation search engine powered by the Grok AI agent. The name “Grok,” inspired by Robert Heinlein’s *Stranger in a Strange Land*, emphasizes the model’s aim for deep understanding.
