 **CoVe-4B** is a compact 4B interactive tool-use agent fine-tuned from [Qwen3-4B-Instruct-2507](https://huggingface.co/Qwen/Qwen3-4B-Instruct-2507) using the **CoVe** (Constraint-Verification) post-training framework. It is trained on [CoVe-12K](https://huggingface.co/datasets/Zichen1024/CoVe-12k), a dataset of 12K high-quality multi-turn tool-use trajectories synthesized and verified by deterministic constraint checking.
 
+The model was introduced in the paper [CoVe: Training Interactive Tool-Use Agents via Constraint-Guided Verification](https://huggingface.co/papers/2603.01940).
