A tool-augmented framework for detecting factual errors in LLM-generated text.
Tool-augmented detection: Integrates LLMs with external tools (search engines, code executors, calculators) to fact-check generated content.
Multi-domain coverage: Handles factual errors across knowledge-based QA, code generation, mathematical reasoning, and scientific literature review.
Component-level analysis: Identifies the necessary components (claim extraction, query generation, evidence retrieval, verification) and shows which matter most.
Practical recipe: Offers a concrete recipe for integrating fact-checking into LLM pipelines, using off-the-shelf tools rather than bespoke detectors.
