SpaceX has recently started pitching itself as an orbital datacenter company. If you buy into that business model (or pretend to), it makes sense for SpaceX to start selling compute early. Their "earthside compute" clients of today are "skyside compute" clients of tomorrow. A part of Musk's old pitch for Starlink was: space-based solar makes perfect sense for powering space assets, and no sense whatsoever for powerin…

Why would it ever be more economical to put datacenters in orbit, rather than on some dirt cheap land?

Because dirt cheap land usually does not have dirt, cheap water or dirt cheap electricity.

Is this admission that google’s proprietary chips etc. are not cutting it? Why would you need a bunch of nvidia GPUs if you have your own silicon? (AFAIK they have their own for both inference and training do they not?)

Kinda; while it does show that overall Google's proprietary chips etc. are not cutting it, it doesn't say if the problem is the hardware itself or the factories to make more of the hardware. Without more information, it could be that Google's hardware is 100x the energy efficiency per token, but they can only make enough hardware for 1% of the tokens there's currently demand for: 1% of your product being 0.01% of your costs isn't nothing, but it leaves the other 99% at full price.

These deals are part of how the AI economy operates. Amodei has explained this in his recent Patel podcast.

1. Building datacenters takes time. Months, if not years. They take billions of investment.

2. AI revenue is highly unpredictable. Sure, you can make predictions, but maybe your competitor releases a better model 2 weeks after your release, maybe the new model you built isn't as much better, maybe the chinese models steal your show, etc.

3. AI revenue grows a lot. Anthropic's case is 10x per year.

4. So if you are off by just a year in terms of how much GPU you actually need, then that means a 90% of your compute capacity is wasted, and you go bankrupt.

As a solution, companies buy compute from each other! If one company's model did well, they can buy compute from the company whose model didn't do well (like in the case of grok). It's beneficial for both sides, so positive sum game. So deals like this aren't something bad in itself.

It's nothing new either. In SAAS deals, you often commit to a certain revenue and then pay extra if your revenue exceeds that amount. And power market is cut in two as well: longer term deals plus spot markets. Spot prices are way higher than the longer term deal prices.

Given it's SpaceX of course there is financial engineering involved: the GPUs aren't actually owned by SpaceX but a daughter company, and it's been financed via loans that are backed by pension funds. So it's already the case that pension funds back bear the risks associated with SpaceX's operations.

Right now, the bulk of the AI bubble sits in such debt statements and not in public markets.

When I hear space I think "that's the perfect location for a data center", since data centers are lightweight, small, require little power, don't need human intervention, have lifetimes measured in decades and don't have to reject heat. Since space easily satisfies these requirements, space is an ideal deployment location for data centers.

This may be one of the rare instances where the sarcasm is obvious without using the sarcasm font

The data link between earth and space has so much bandwidth.

There are sensors in space that send data to earth it gets processed and then the data is sent back to space then to the end user back on earth. If you do the compute in space you save the space-earth transfer time twice. Latency and availability of bandwidth are both factors.

There may be limited utility for this outside of military.

Is there any data on whether Google, Amazon, Microsoft, Anthropic, OpenAI etc are most cost efficient in getting datacenter compute online and operating it? I'd be interested in how large the range is here across company and region and specific data center and how it relates to companies like Hetzner if at all.

I don't think they are most efficient for small GPUs. I think they might only be the one which have capex and certainty required for multimillion dollar purchase of GB200 NVL72 or something of that scale.

Space-based datacenters simply won't work. That people are talking about them shows Musk is the greatest snake oil salesman the world has ever seen.

You think the military can’t or won’t dump billions into this to make killing people with drones more effective?

It’s a engineering challenge not impossible.

Can anyone explain how the thermals will work? One of the biggest challenges on Earth is cooling the data center, and it's at least as challenging in space.
