Alex Zhang says Headlong uses the RLM abstraction and can continue thinking about problems in its context even when it is not being queried; he considers this more interesting than the RLM abstraction itself.

“they are using the rlm abstraction but they're doing something much cooler than the rlm uh which is like they have a system that kind of what they call like thinks persistently so even when you don't query it”

“it has a way to think through problems that it has in its context”
