This is an intermediate checkpoint that we used in our [1st place solution of the 2025 BEHAVIOR Challenge](https://github.com/IliaLarchenko/behavior-1k-solution).

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

It is not part of our [final submission](https://huggingface.co/IliaLarchenko/behavior_submission). Also, we didn't run the whole evaluation of this checkpoint, but we would expect it to achieve a 15-20% q-score.
