| # SparseQID checkpoints |
|
|
| Checkpoints for **Online Multi-Camera 3D Tracking via ID Prediction over |
| Recurrent Sparse Queries**. Source code and instructions are available at |
| [playbox-dev/SparseQID](https://github.com/playbox-dev/SparseQID). |
|
|
| The submitted model is `ngc-frozen_v128_pe30_it6k.pth`. It achieved 38.01 HOTA |
| on the 2026 AI City Challenge Track 1 test set. |
|
|
| ## Download |

|
|
| ```bash |
| hf download playbox-dev/SparseQID \ |
| --include "checkpoints/**" \ |
| --local-dir . |
| ``` |
