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· 17 févr. 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!

ruing technical terms here. Mixture of Experts (MoE) has literally nothing to do with what xAI actually shipped in 4.20.
This isn't one singular model, dense or MoE, with internal routing or sparse experts. It's four separate replicas (instanced) running at once in a quorum-st

It’s worth pointing out that ChatGPT 5.2 performed significantly worse on this test, as shown in the first image.
The second image shows Opus 4.6.
The third image shows Gemini Pro.
The fourth image shows Grok 4.2.

Grok is most physically accurate of the four.
Opus rear bike frame makes no sense structurally, there is no connection from pedals to rear wheel, both legs of Pelican are on the right side of the bike and handle bars are disconnected.

The Grok 4.2 release candidate (public beta) is now available for use. You need to select it specifically.
Critical feedback is appreciated. Unlike prior versions of Grok, 4.2 is able to learn rapidly, so there will be improvements every week with release notes.

I just got access to Grok 4.20 beta & I’m testing it on biomedical questions; I can already say it has greatly improved. In fact, for a very complex experiment outcome prediction, Grok 4.20 gave an amazing response! I’d even say it’s the best I’ve seen from any model! Looking 👍!

The monthly cost per illegal alien in Vienna far exceeds the average Austrian's salary.
It’s pretty shocking when you look at the numbers: the city is paying up to €18,000 a month for every unaccompanied, underage asylum seeker, and the reality is, many adult migrants just

The Spanish police have just announced that the real figure of migrants being “normalized” under Pedro Sanchez’s new laws is actually 1.35 MILLION.
The government originally lied and said it was 500,000.
The later revised it to about 800,000.
