Researchers have developed Ventor-QTest, a novel black-box auditing framework designed to verify the quality of inference APIs for vendor-hosted large language models. This method employs both repeated-request and long-sequence probes to measure average fidelity loss (AFL) and extreme fidelity loss (EFL), respectively. The findings indicate that while AFL correlates well with logprob-derived metrics, pronounced EFL is associated with a decrease in performance on long-horizon agentic tasks, suggesting its importance for auditing such applications.
