| # VideoSearch-R1 ActivityNet Stage 1 | |
| This is the Stage 1 VideoSearch-R1 checkpoint trained for ActivityNet, presented in the paper [VideoSearch-R1: Iterative Video Retrieval and Reasoning via Soft Query Refinement](https://huggingface.co/papers/2607.00446). | |

| Stage 1 is trained from the Qwen3-VL base model on constructed video retrieval and temporal grounding supervision. It is intended as the initialization for Stage 2 training or as a released checkpoint for ablations. | |
| ## Usage | |
| Use with the VideoSearch-R1 codebase: | |
| ```bash | |
| bash scripts/data_construct/download_preextracted_data.bash activitynet | |
| EVAL_GPUS=0 bash scripts/inference/inference.bash activitynet --checkpoint VideoSearchR1/activitynet-stage1 | |
| ``` | |
