Grok 3 is the most sophisticated chatbot of xAI, with deep reasoning and real-time internet access. It presents excellent STEM, and more skills.

Introduction

Grok 3 Beta represents a landmark moment for xAI. Trained on the Colossus Supercluster with ~200,000 GPUs and 10× the amount of compute as before, it has two reasoning models: full Grok 3 (Think) and leaner Grok 3 mini. “Think” mode engages chain-of-thought reasoning that may take seconds to minutes, and it supports multi-step problem-solving such as math or coding. Early benchmarks indicate 93.3 % on the 2025 AIME, 84.6 % on GPQA, and 79.4 % on LiveCodeBench. Grok scans real-time web and X via DeepSearch for current info. Initial rollout is via X Premium+ and xAI’s SuperGrok, with enterprise API coming soon.

Review

Grok 3 is the most sophisticated chatbot of xAI, with deep reasoning and real-time internet access. It presents excellent math, science, programming, and world knowledge skills. The reasoning is clear and systematic but provides responses with its signature humorous tone. The natural modes such as “Think” and “Big Brain” provide fine-tuned control over response depth. Critics mention infrequent lateness and imperfect quality, yet on the whole, Grok 3 excels for users requiring lucidity and calculation. Sharp thinking, sometimes tardy, great for intricate questions.
