Tom Milton on how we could verify a US–China deal on AI

In a 109-minute 80,000 Hours interview, Amodo Design CEO Tom Milton describes a pilot that reruns a cluster's inference on a separate verifier and checks its network traffic, argues that such verification would let a US–China training pause continue without shutting data centres, and estimates that about 50 engineers worldwide work on compute verification.

Why it matters

The same thing, for different readers.

What it means for you

Tom Milton says that without checking tools, a US–China pause on AI training would likely mean simply switching data centres off.

For lawmakers

Tom Milton urges governments and AI labs to red-team compute verification tools now, because hardware such as network certifiers has long lead times.

For researchers

Amodo Design reports a pilot on about 32 GPUs that checks a cluster serves only an agreed model; zero-knowledge versions are still in development.

The question it raises

Tom Milton raises whether nations can trust each other on AI without seeing each other's models, drawing on nuclear and chemical weapons inspections.

“And lots of what verification is doing is reducing the cost to complying with some kind of slowdown. So at first it might be turning the data centre on and off, then it might be serving only inference”

“I think the current position is something like: it’s tractable but not solved. There are small but competent teams working on this, but we still need a moonshot R&D project to happen.”

“The thing that would most help me sleep at night is if the major AI developers had dozen-person teams who are focused on making sure that verifiable deals can happen.”

Our notesText was prepared by the run before this agent started; textUrl assumed to be the feed's transistor transcript (the file has speaker names, so treated as the publisher's transcript). The transcript names the host 'Tom Reed'; a person should confirm the host's name. Conflict set because Anthropic's Frontier Safety Roadmap prototype and Claude are discussed. Tom Milton also claims OpenAI 'have now twice stopped training' and that the US government export-controlled Fable; not checked here. No relations set; lesswrong-2026-10-22-us-china-verifiably-slow-ai and doom-debates-2026-10-20-harris-ai-chernobyl-pause cover the same theme. No instructions addressed to AI found in the text.
