Jasper Lu(@lu__jasper):Hoping someone can explain to me what's going on here. The report says they trained multiple mixRL teachers, then used MOPD to combine those teachers into a student model. But..the team literally live-streamed their RL run, and then released model + report just one day after it finished. How does this timeline work out? I would assume the streamed RL run is just a final climb after MOPD, but the paper doesn't mention anything about a final climb. Maybe the livestreamed run is only for one of their mixRL teachers, and they did MOPD quickly in the 24 hours before launch?
