This repo contains model checkpoints of the 1st place solution of the [2025 BEHAVIOR challenge](https://behavior.stanford.edu/challenge/)

Refer to [this repo](https://github.com/IliaLarchenko/behavior-1k-solution) to use the models.

Our [tech report](https://arxiv.org/abs/2512.06951).

This model achieved ~26% final score on both Public and Private eval datasets.

The repo contains 4 checkpoints that are supposed to be used for different tasks:

| Checkpoint | Task Count | Task IDs |
|------------|------------|----------|
| **Checkpoint 1** | 20 tasks | 2, 3, 5, 6, 10, 11, 13, 14, 15, 19, 23, 24, 25, 28, 29, 34, 42, 44, 47, 48 |
