Google Built It. I Ran It on AWS.
The provisioner lives at antweiss/agent-substrate-on-aws, as the AWS counterpart of upstream's GCP setup tooling. The installer overlay is in PR #2241 while the maintainers decide where cloud-specific installers should live.

DeepSeek Elastic Compute (DSec)
That's not quite right. A recurring trend in ML is figuring out how to get a Lambda like interface for the the particular quirks of ML workloads (source: I worked on an open source one years ago for inference). Recently, there's been a lot of interest in doing this for agent workloads. Google recently released something called ax that is similar in spirit. The core of it is this: https://github.com/agent-substrate/substrate
At a high level, agent sandboxes have peculiar needs. Agents are really bursty, but also long lived. You need low latency suspend/resume calls. Checkpointing and recovery have some particular considerations. And naive approaches are often really wasteful, but over optimizing without harming durability, isolation, or consistency in performance can get tricky.
This is the new hot infra topic for agent swarms, for the time being. Whether that's impressive or not is up to the reader I guess, but it's a pretty involved project nonetheless.

Sources: google/ax on GitHub, Agent Substrate, the Hacker News launch thread, and Traictory's review of the launch. Scale claims are vendor claims unless a benchmark says otherwise.

Because of Substrate's efficiency in how Actors run, you can run a plethora of Actors on a Single Worker. Google tested this with 250 Stateful Actors across only 8 Pods (the Workers).
