Grok 4.2
Launching today
Grok 4.2 is a native multi agent system where four specialized heads share the same context. They run parallel reasoning and debate internally to cross check facts before answering. It also features a rapid learning loop that improves every week.

Hi everyone!
There are so many new models dropping lately, but 4.2 is one of the very few that instantly feels genuinely innovative. Haven't experienced this kind of raw fascination in a while.
The coolest part is being able to audit the thought process and actually watch the four agents battle it out before giving you an answer.
I'd say the structural shift is what makes this special. Instead of a single monolithic brain, you are querying a native team. You have:
Grok (Grok Leader) coordinating everything
Harper (Agent 1) pulling real-time research & fact-checking
Benjamin (Agent 2) pushing heavy logic, math, and code verification
Lucas (Agent 3) injecting creative angles and out-of-the-box ideas
They debate and peer-review internally, which is why the hallucination rate on complex engineering tasks is insanely low right now. The architecture also supports rapid learning, meaning the weights aren't static after launch. We are getting weekly improvements based on user feedback.
And according to Elon:
If you want to see this internal debate dynamic in action, open your Grok, manually select 4.2 in the menu and throw your hardest open-ended problem at it.
