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):we'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! https://t.co/c4dQhEzSCs ...
