 **TokenHD** is a token-level hallucination detector trained on top of [Qwen/Qwen3-4B](https://huggingface.co/Qwen/Qwen3-4B) using the TokenHD pipeline. It assigns a hallucination probability to each token in an LLM-generated response, enabling fine-grained localization of errors without requiring predefined step segmentation.
