Keep in mind while this is the date they officially became part of SpaceX, they have already been collaborating on building models together. So don't expect a significant bump in performance on new Grok models due to the additional data from Cursor--that bump already happened with Grok 4.5[1] and now 4.6.
There still may be Opus->Fable type bump when they finish training larger models. Remember, Grok 4.6 is still Opus-sized and they have larger models in training.
GMoromisato 20 hours ago [-]
I'm skeptical of this deal. Cursor led the way on agentic coding, but Claude Code and Codex have replaced it. [I use Codex for everything now.]
Still, I'm hearing that Grok 4.6 is almost as good at coding as Codex, but lots cheaper. [My network is also down on Claude--Opus 5 seems like a regression.]
The optimistic scenario would be Grok being a fast-follower with cheaper rates, and staying ahead of open source models. If they can pull that off, and convince enough developers, then maybe they've got a chance.
But $60B seems insane to me. What's Cursor's market share relative to Codex and Claude Code? If it's not meaningful, then it's $60B for an acquihire.

SpaceX is betting that the world will be compute/energy constrained by 2030 and that orbital datacenters will become cost-effective for inference.

For some perspective, the entire heat rejection system on the ISS at peak can do a little less than one rack of dense AI compute power.
All of that plumbing, all of that area, all that stuff to put in orbit just to cool one rack of compute equipment.
How much stuff do we need to put up there for each rack? The External Active Thermal Control System on the ISS is ~20,000lbs, about 10 tons. How many racks are in a single datacenter? The Colossus is allegedly ~1,500 compute racks, ignoring other equipment. So that's like 15,000 tons for just the cooling equipment if its like the ISS. At SpaceX's current public launch costs (which makes a profit for them, so not base costs) to launch that much stuff is somewhere around $40B. Just the launch cost for the cooling equipment alone for just one datacenter building worth of pure compute capacity, that isn't even that big compared to what companies are talking about building.
All of that is very rough back of the napkin math. I don't expect that to be the actual numbers at all, but I'd imagine somewhere in that neighborhood unless they've got something really radical up their sleeve.
They better have a much better way to cool these things than what the ISS is doing.
That's ~13 tons per megawatt, or 1,330 tons for 100 MWs. That's 13 launches of Starship (at $10 million per launch, or $130 million). Of course, that's probably 600 individual satellites, at maybe $5 million per, so we're at ~$3 billion to deploy 100 MW to space.
You can sell 100 MW of compute for $3-4 billion per year, so SpaceX would make their money back in 1 year.

Did the Cybertruck have 500mi of range? Was there a $40k model at launch?
GMoromisato 13 hours ago [-]
I think we're in full agreement.
I don't know if orbital datacenters will work out--it depends on the price of launch and the price of tokens in 2030. Maybe they'll try it and abandon it. We'll see.
But my point is that if it does work, if they can be cheaper than terrestrial tokens, then SpaceX can dominate the market because no one else is even close to being able to deploy orbital compute.
And if it doesn't work, SpaceX will be fine because they are printing money with Starlink.
Cybertruck is a good example--they never hit their sales targets, but Tesla is fine because they are making money on Model Y and they are investing in Robotaxi (which has a bigger potential than Cybertruck anyway). And if Robotaxi doesn't work out, they will pivot to a cheaper model or something.
SpaceX will be fine, not because orbital datacenters are guaranteed, but because they keep betting on things that may or may not work, but if they do work, they make a ton of money.

dgellow 16 hours ago [-]
They do and you’re the one spreading misinformation… the amount of energy you need to radiate for inference GPUs is enormous compared to any computer currently used in space. Energy dissipation by radiating is literally the least effective method and would require insanely large radiators just to be effective on paper. You also need to mitigate bit flips, meaning you throw away around 2/3 of your compute capacity.
And that’s just the most basic things, before taking in account ALL the other problems you face doing compute in space someone with expertise in the domain could mention.
Datacenters in space is a grift that won’t happen in any meaningful capacity and can be debunked by a 15y old who followed their physics courses
GMoromisato 15 hours ago [-]
You've listed:
1. Radiating heat needs large radiators
2. Bit flips require extra compute capacity
Neither of those violate the laws of physics. As I said, they may not work economically, but that depends on a large number of unknowns, including the cost per ton to orbit and the cost per GW of new power capacity on Earth in 2030. If you have a time machine and know those numbers, then can I please borrow your time machine?
Moreover, when you say, "ALL the other problems ... someone with expertise in the domain could mention," you're saying either:
A) SpaceX engineers do not have expertise in this domain.
B) SpaceX engineers are hiding all the problems that they know about.
B is basically a conspiracy theory. It is one YouTube video away from saying the moon landing was a hoax.

Do you know anyone that works at SpaceX? They get paid well, yes, but my friends who work there say they work you really hard. The bet that's being made is that there will be advancements in materials science that make data centers in space viable. If you hypothesize that there's a way to cool things down in space if you just had the right material to do it, it makes sense. Starlink satellites are already compute plus solar panels. Just scale it up! Or course "just" is doing a lot of work here, but that's the theory.

I get it and yet I don't. On one hand, my experience with Cursor (albeit limited) tells me that it's a perfect fit with Elon's other ventures. Then again, I don't see how there's anything so special about it that SpaceXAI would want to acquire it for either the software itself or the talent behind it. It seems more likely that acquiring Cursor is a way to get more users for Grok, seeing as how it still has a very small share of the market.
freedomben 20 hours ago [-]
I've never seen the appeal of cursor either, but then I'm a decades-long vim (now neovim) guy and don't use IDEs in general. But for me claude/codex TUIs are a great way to fit agents into my workflow.
My suspicion is that it's a way to break into more developer workflows for Grok, even if the market share is relatively small. I've never used grok and don't plan to at this point, but I have highly respected friends who say it is pretty damn good, and some of them even started using Cursor because of this pairing, so anecdatally at least it does seem to be working.
melodyogonna 20 hours ago [-]
Grok has started competing with frontier models on coding thanks to Cursor's data, with SpaceX's massive compute they can undercut competition on price, which makes the offering real appealing.

C) SpaceX engineers enjoy their cushy salary funded by a guy who won't take "that doesn't make sense" for an answer to work on rockets and neat technology, even if it may never really work out.
You're missing C) SpaceX engineers know it's a bad idea, but can't say anything because it's the tyrant manchild's latest obsession, technology constraints be damned.
Remember the vision-only FSD? How's that coming along?
Imho, there's only one reason that justifies Musk's space-based compute obsession: sovereignty.
Specifically, avoiding terrestrial country's.
This isn't about AI in space (though I'm sure dumb investors love that), it's about uncensorable Twitter in space, beamed down to Starlink terminals.
Which would be one of the few things you'd care about, if you were one of the richest people on the planet... but still subject to those damned nations and their meddling laws.
Unless he's offering it to the aliens orbiting his magical lawless space data centers.
Short of countrywide ku-band jamming and/or drone-based RDF at scale, what's the country going to do?
It was one thing when you needed a C-band dish to receive, but much harder to deal with a 1-2 ft dish.

Maybe this is horse trading: SpaceX pays an insane price in stock for a vibe coding app, Trump will help Terafab and Starlink in any way possible. There are probably other Cursor investors among the Trump clan.
Good that there is now an administration that creates jobs, does not engage in foreign wars and has ended the Ukraine war in 24 hours.

But some other company took the trademark of E in relation to cars...
Besides its following, does Cursor have any sort of moat? It's VS Code with a harness right?
SpaceX to buy Cursor for $60B

My suspicion is that it's a way to break into more developer workflows for Grok, even if the market share is relatively small. I've never used grok and don't plan to at this point, but I have highly respected friends who say it is pretty damn good, and some of them even started using Cursor because of this pairing, so anecdatally at least it does seem to be working.
I've now switched to Grok 4.6, I was previously using Opus 4.8 but Grok is good enough now, and way cheaper which is the important part.

I mean I get that we can all dislike this move but it might the best way to get into the race to become one of the top labs. Ofc Grok 4.6 is not there yet, I have seen people claim it's quite good and it is but it's a marginal improvement over the mid tier models from the top 2.
And it's certainly worse than the recent GLM 5.3 (especially once we get the weights for it).
Sol xhigh is my default rn.
