The speaker says Fable was the best model for RLM for a long time because it supported dynamic workflows, suggesting that this capability had been trained into it to some extent.

“actually running meaningful experiments over like scaling out new harnesses like maybe post-train scaling out on different harness designs like i think we can actually get very meaningful knowledge or gains from doing this kind of thing whether it's an rlm or whether it's something different and that's exciting because i think for example if you train a lot on fable for a long time was the best model for rlm because they had dynamic workflows and it was”

“And it was pretty obvious that like this was a capability that was somewhat trained in,”
