New features: DeepSearch & Think

Grok 3 comes with two significant enhancements:

DeepSearch: A cutting-edge AI agent designed to synthesize key information, navigate conflicting facts, and deliver precise insights from complex data. 

xAI states that DeepSearch produces a “concise and comprehensive report” to help users stay ahead in an ever-evolving world.

Think Mode: An advanced reasoning feature optimized for math, science, and coding. Users can ask Grok to “Think harder” for more accurate and sophisticated responses, making it ideal for technical problem-solving.

How to access Grok 3?

Grok 3 is available for free (for now) via multiple platforms:

• X (formerly Twitter): X Premium+ and SuperGrok users receive priority access.
• iOS App: Available for Apple users.
• Web Platform: A dedicated website is live for broader accessibility.

An API release is planned soon, allowing developers to integrate Grok 3 into their applications. xAI encourages developers to “join us to build the future,” hinting at continuous improvements and expansions.

Elon Musk’s vision for AI dominance

Musk’s xAI has positioned Grok 3 AI as a revolutionary model, claiming it outperforms industry leaders in multiple benchmarks. 

With open access (for now) and powerful new features, Grok 3 is set to challenge the dominance of ChatGPT and other major AI models.

Will this be the game-changer Musk envisions, or is this another ambitious claim? Only time will tell, but Grok 3 is free for now—at least “until our servers melt.”
