IliaLarchenko/behavior_50t_checkpoint

This is an intermediate checkpoint that we used in our 1st place solution of the 2025 BEHAVIOR Challenge.

This checkpoint is obtained by training the policy on 50 tasks simultaneously for ~2 weeks.

It is not part of our final submission. Also, we didn't run the whole evaluation of this checkpoint, but we would expect it to achieve a 15-20% q-score.
