As artificial intelligence technology advances rapidly, Elon Musk's xAI launched Grok 3 in February 2025. Dubbed the "smartest model on Earth," it claims to surpass OpenAI's GPT-4o in math, science, and coding benchmarks. But can it truly disrupt the AI landscape and challenge ChatGPT's dominance? This in-depth review explores Grok 3's core functionalities, pricing, and how it stacks up against competitors like ChatGPT and Gemini.
What Is Grok 3? xAI's Ambitious Creation
Grok 3 is xAI's third-generation AI model, officially released on February 17, 2025. Powered by the Colossus Supercomputing Center (equipped with 100,000–200,000 NVIDIA H100 GPUs), its training computational capacity is 10–15x stronger than its predecessor, Grok 2.
The name "Grok" originates from the sci-fi novel Stranger in a Strange Land, meaning "to understand deeply." Elon Musk positions it as a "truth-seeking" AI, emphasizing reduced bias and practical answers.
Key highlights:
- Free access for all X users (launched February 21).
- SuperGrok paid tier (~NT$1,000/month) unlocks advanced features.
- Real-time data integration via X platform.
- Personalized interactions with distinctive voice modes.
