Grok-3: Elon Musk’s xAI Launches “Scary Smart” AI to Challenge OpenAI and DeepSeek
Table of Contents
The AI arms race reached a pivotal moment on February 18, 2025, as Elon Musk’s xAI unveiled Grok-3, a next-generation AI chatbot touted as the “smartest AI on Earth.” With record-breaking benchmarks, advanced reasoning, and a $10 billion supercomputer, Grok-3 isn’t just competing with giants like OpenAI and DeepSeek—it’s redefining the rules of the game.
What Makes Grok-3 a Game-Changer?
1. Unprecedented Computational Power
Grok-3 was trained on xAI’s custom-built supercomputer, “Project Chocolate,” featuring 200,000 NVIDIA H100 GPUs—a tenfold increase over its predecessor. This infrastructure allowed xAI to complete pre-training in just 122 days, enabling Grok-3 to process complex queries 10x faster than Grok-2 19.
2. Advanced Reasoning and DeepSearch
Grok-3 introduces “Big Brain” reasoning mode, which mimics human-like problem-solving by breaking down tasks into logical steps. Paired with DeepSearch, a research tool that explains its thought process, Grok-3 can tackle PhD-level physics questions and generate code for hybrid games like Tetris-meets-Bejeweled 612.
3. Benchmark Dominance
- Chatbot Arena Score: 1402 (first model to cross 1400) 1
- AIME 2025 (Math): 52/75 vs. GPT-4o’s 38 12
- GPQA (Science): 75/100, outperforming Gemini 2.0 and DeepSeek-R1 12

Technical Breakdown: How Grok-3 Works
Training and Architecture
Grok-3’s training dataset includes court filings, synthetic data, and real-time user interactions. Unlike OpenAI’s GPT-4o, xAI emphasizes “truth-seeking” over political correctness, though early tests show lingering biases in responses 9.
Multimodal Capabilities
While Grok-3 excels in text and code generation, its image creation lags behind rivals like o3-mini. However, a voice interaction mode and video generation features are slated for mid-2025 912.
