Grok 4.2 will be about an order of magnitude smarter and faster than Grok 4 when the public beta concludes next month.
Still many bug fixes and improvements landing every day. The public beta gives us more critical feedback to address.
Aaron Burnett@aaronburnett· Feb 17, 2026we're already using Grok 4.20 (agents) in our research process, from a research perspective it does feel like we jumped another 9.
I'm particularly a fan of the improved sourcing!
