“To have a stateful agent, you need like an LMOS because you need something other than the LM to kind of maintain state.”

Packer: Sleep-time compute during idle downtime is a major missed opportunity
“And practically speaking, you know, machines, they're not like humans, they can be run all the time. And there's a ton of downtime, both in advance of like questions being asked also like After questions have been asked too. So I think beyond just scaling at t…”

Insight
Packer: True AI agents run continuously rather than waiting for triggers
“And I think that's another aspect of like what makes something agentic, like not having to have a user send an event to trigger the machine to turn on, just allowing these machines to run all the time.”

PredictionNot checkable as stated
Packer: Background sleep-time agent architectures will be standard within two years
“I think those two, yeah, I think similar to memgpt, I think they're definitely like very good reference designs for just what's coming next. I think this sort of thing is, is just gonna be like the norm in like a year or two years.”

Insight
Packer: Sleep-time compute re-represents token state into easily queryable formats
“In the test time compute setting, you know, here, the state is tokens and the kind of like sleep time, like indexing process is a re-representation of those tokens into something that is like more easily queryable and more flexible.”

Packer: Sleep-time compute offers Pareto improvements across Claude 3.7 and DeepSeek
“It's like pretty consistent across like both 3.7 deep seek, three mini, which all like the way you actually scale the x-axis here is fundamentally quite different in each case with 3.7 extended thinking mode. The parameter you provide to scale it is different …”

Packer: Most test-time compute benchmarks assume stateless context delivery
“Most of the evaluations and work in this area, they kind of assume you get all of your context at test time. You get a math problem, you get like the entire setup and the question at test time.”
