You mean that if you were Anthropic, you'd build the data centers on every continent? Can you explain your reasoning?

We're talking about billions of dollars of extra capex if you take the "let's build them everywhere" side of the bet instead of "let's build them in the cheapest possible place" side. It seems to me that you'd have to be really sure that you need the data center to be somewhere uneconomical. I think if you did build them in the cheap place, it's a safe bet that you'll always have at least enough latency-insensitive workloads to fill it up. I doubt that we would transition entirely to latency-sensitive workloads in the future, and that's what would have to happen for my side of the bet to go wrong. The other side goes wrong if we don't see a dramatic uptick in latency-sensitive inference workloads. As another comment pointed out, voice agents are the one genuinely latency-sensitive cloud inference workload we have right now; they do need low latency for it. Such workloads exist, but it's a slim percentage so far.

I believe I'm taking the safe bet that lets Anthropic make hay while the sun shines without risking a major misstep. Nothing stops them from using their own data centers for cheap slow "base load" while still using cloud partners for less common specialized needs. I just can't see why they would build the international data centers to reduce cloud partner costs on latency-sensitive workloads before those workloads actually show up in significant numbers.

You can build geographically close one tomorrow, when you start earning money today. US-EU latency is like 100ms, AI can handle it just fine

They want it, sure. Customers want everything if it's free, but this is about what they value with their money. In this thought experiment, you're Anthropic, not the customer. You're making a choice that's best for Anthropic. Will Anthropic lose customers because the latency is higher? No way. Customers want low cost and lots of usage more than they want low latency. In a cutthroat race to the bottom, there's no room to "give away" massively expensive freebies like a data center near every population center when the customer doesn't value those extras with actual money. It's the same reason we all tolerate the relatively slow batched token generation rate--the batching dramatically lowers the cost, and we need low cost inference more than we want fast generation. If the cost goes up we'll actually leave, for real.

After the initial announcement of "fast mode" in Claude Code, did you ever hear about anyone using it for real? I didn't. Vanishingly few people are willing to pay extra for faster inference.

Remember that the time-to-first-token is dominated by the time to process the prompt. It's orders of magnitude more latency than the network route is adding. An extra 200 milliseconds of network delay on a 5-10 second time-to-first-token is not even noticeable; it's within the normal TTFT jitter. It would be foolish to spend billions of dollars to drop data centers around the world to reduce the 200 milliseconds when it's not going to reduce the 5-10 seconds. Skip the exotic locales and put your data centers in Cheap Power Tax Haven County, USA. Perhaps run the numbers and see if Free Cooling City, Sweden is cheaper.

The only AI use case that cares about latency is interactive voice agents, where you ideally want <200ms response time, and 100ms of network latency kills that. For coding and batch job agents anything under 1s isn't going to matter to the user.

Easy solution - use hyperscalers with super expensive API charge only when latency really matters. Otherwise build your own DC. Easy to expect customers don't care latency that much over money.
