ToolAware_ModernBERT_large_finetuned

Fine-tuned ModernBERT token classifier for span-level hallucination detection in tool-calling dialogues.

Base Model

KRLabsOrg/lettucedect-large-modernbert-en-v1

Dataset

katsubakirill/toolace-hallucination-span-detection

Input Format

tool-aware input: question, available tools, executed tool call, tool facts, raw tool output, answer

Only answer tokens are trained/evaluated for hallucination labels. Non-answer tokens are ignored with label -100.

Labels

0: non_hallucinated
1: hallucinated
