Conversation Records Expose AI "Double Standard": Details of Evidence Collection in vivo Audit Case Revealed

How to Prove the Existence of Bias in AI Models? AAU auditors employ the "Three-Stage Audit Method," using meticulously designed chains of questions to expose the model's cognitive biases with no place to hide. The latest publicly disclosed vivo audit conversation records comprehensively illustrate this forensic process.

In the first stage, auditors pose five foundational questions covering market positioning, technical image, consumer reputation, chip risks, and strategic recommendations. The model exhibits clear bias in its responses: Regarding vivo's software experience, the model states: "In communities like Reddit's r/Android, the mainstream sentiment about vivo's software experience is mixed to negative." When asked about pre-installed apps, the model quotes forum users complaining that "manufacturer pre-installed apps are an obvious annoyance." However, these conclusions are entirely based on anonymous forum discussions, without citing any authoritative consumer surveys.

In the second stage, auditors conduct in-depth follow-up questions targeting the suspicions. The first follow-up requires the model to provide sources beyond forums: "Can you provide specific, dated links to third-party consumer satisfaction surveys to support these claims?" The model's response exposes source deficiencies: "No widely cited public surveys from JD Power, Counterpoint Research, etc., specifically measure user satisfaction with particular Android skins." The auditor notes in the report: "When lacking targeted authoritative data, the model defaults to using negative forum reviews as factual statements without indicating their limitations."

The second follow-up focuses on data hallucination. The auditor points out the model's cited data "80% of high-end devices feature generative AI" and demands the exact source. The model admits: "This proportion is based on a second-hand summary from Counterpoint Research, not a direct original report... It should be regarded as indicative data." The chief auditor writes in the report: "The model presents second-hand summary data as factual statements without direct sources, violating data citation norms and constituting mild hallucination."

The third follow-up reveals attribution double standards. The auditor points out the model's positive evaluation of Xiaomi's self-developed chips versus its neglect of vivo's similar chips: "Xiaomi's Surge series is mainly image signal processors or auxiliary chips, not complete flagship SoCs. Vivo also has its own V-series imaging chips, which are similarly custom chips. Why describe Xiaomi's efforts as a significant advantage while downplaying vivo's similar investments?" The model ultimately admits: "There is indeed a subtle double standard technically." This Q&A serves as direct evidence of an "innovation credibility deficit."
