Ask HN: Is there an AWS Lambda equivalent for building AI agents?

Not exactly equivalent, but I am working on a project that might achieve some of the same goals: https://www.agentstation.ai/

We are providing the infrastructure for AI agent computers at scale, with an API to drive agent actions. You can use prompted workflows (ala the Claude Computer Use API), or use your own models to drive actions within the workstation.

Is this what you were thinking? Happy to answer any questions on it!

Can you elaborate?

What do you mean?
