The speaker contrasts the Darwin-Godel machine's two levels with their system's three levels: outer- and inner-loop agents conducting automated research, and downstream tasks that include harness engineering.

“In their case, there's only two levels, like there's an agent optimizing.”

“another agent doing coding whereas in our case there are three levels there's an outer loop agent there's a interloop inner loop agent both are doing auto research and they there's another layer which is the downstream tasks and some of them are actually harness engineering tasks”
