Grok

Origins & Model Evolution
Released in November 2023, Grok progressed from version 1 to Grok 2 in 2024, and Grok 3 in February 2025—powered by xAI’s Colossus supercluster (200k NVIDIA GPUs). 

Real-Time Knowledge Integration
Grok uniquely accesses live data from X and the web, enabling the most up-to-date context in its responses.

Advanced Reasoning Features

DeepSearch: A search agent that synthesizes and reasons through information to provide concise, contextual summaries.

Think Mode: Offers transparency into the model's internal reasoning steps aitoday.com+5builtin.com+5linkedin.com+5.

Multimodal & Creativity Support
Grok supports both text and image generation (via Aurora/FLUX) and can produce code, graphs, emails, and creative texts.

Personality & Use Cases
Known for being more candid and edgy than other AI systems—Grok often answers questions that other chatbots avoid. This style suits marketing, trend insights, idea generation, and creative support—but may require verification for sensitive content.
