Grok 4.2

The next leap. Rapid learning architecture, multi-agent collaboration, and continuous improvement from real-world feedback. Grok 4.2 isn't just a model — it's a system that gets smarter as you use it.

API beta access applied for. Coming to Vibing with Grok as soon as it's available.

API Beta

What we know so far

Rapid Learning Architecture

Unlike previous versions, Grok 4.2 features a “rapid learning” architecture. The model sees continuous improvements now that it's open for public use — it gets better from real-world feedback in near real-time.

Multi-Agent Collaboration

Grok 4.2 moves from solo to collaborative. The system integrates conclusions drawn from multiple agents into a final answer, ensuring responses are accurate, deep, and highly readable. This is a fundamental shift in how AI reasoning works.

“Starting to correctly answer open-ended engineering questions”

Per Elon Musk on X, Grok 4.2 “performs remarkably better than 4.1” and is “starting to correctly answer open-ended engineering questions” — a domain where previous models struggled. This suggests major improvements in reasoning depth.

Available Now on grok.com

Grok 4.2 is live on grok.com, X, and mobile apps. You must explicitly select “Grok 4.2” in the model picker to activate. The API beta is rolling out — we've applied and will integrate it into Vibing with Grok the moment access is granted.

What this means for Vibing with Grok

Smarter Agents

Multi-agent collaboration means your custom agent profiles will produce even better results.

Continuous Improvement

The model improves from feedback. The longer the community uses it, the better it gets.

Better Code Workflows

Open-ended engineering improvements mean better code generation, debugging, and architecture advice.

Same Incredible Price

Expected to maintain xAI's pricing. The best AI at a fraction of the cost.
