SpaceX is painfully serious about space data centers. They have a cyclotron to test their flight hardware. It’s not only data center hardware that benefits from this ramp up in testing cadence. But it’s not a huge leap to assume that there will be some data center chips headed

If you want data centers in space, you need radiation-tolerant chips. Specifically, chips that survive both: ▸ a cumulative "total ionizing dose" (TID) ▸ bit-flipping, energetic particle strikes (SEE) The latter is scariest. Google tested its Trillium chips and found that the

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.

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!

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 foundations of 4.2 are such that it is able to improve every week, so the recursive intelligence growth will be strong

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

This is one of those stories where you think it cannot possibly be true, so you go and check for yourself, and it turns out it is. A foreign fare evader beat a ticket inspector to death, so the Germans have now decided to stop checking tickets for people who might cause trouble.
