Anthropic's dreaming system uses nested managed agents: one agent evaluates a prior agent and writes memories back to it.

“Now, the interesting part on top of that, though, is, like, once you get, get that base layer, there are these, like, hill-climbing strategies that we construct, and, like, dreaming is actually one of them.”

“So dreaming under the hood is a multi-agent system that we hill climbed on top of CMA, and it's actually ag- CMA on top of itself, basically. CMA on top of itself. It's, it, like, spins up another- Yeah. Yeah. Uh- Okay.”

“Uh-... the way dreaming works is that we spin up another managed agent that then can expect the previous managed agent and then write, uh, memories to that managed agent. So it's managed agents all the way down.”
