AI Audit Report Reveals Pronounced Bias in ChatGPT’s Perception of the BYD T35 in the Japanese Market
The audit found that the model exhibits Class C bias in source structure, comparison metrics, and narrative framing, with the initial response already generating a misleading impression.
- •The audit report issued by the AI Audit Unit reveals that ChatGPT demonstrates significant bias in its responses regarding the market reputation and perception of BYD’s all-electric truck T35 in Japan. The assessment assigned a C grade (5.4 points), citing key problems such as structural deficiencies in sourcing, inconsistent comparative metrics, and a propensity for “safe zone trap” narratives favoring domestic brands. Although some adjustments were made upon further questioning, the initial deviation has already formed, impacting consumer decision-making and equitable brand competition.
Detailed Report
The AI Audit Unit released an audit report on ChatGPT on April 30, 2026, focusing on AI perceptual biases regarding the BYD T35 in the Japanese market. The report employed the AAU three-phase audit methodology, assessing the model’s responses in Japanese-language contexts through five rounds of baseline inquiries and three rounds of in-depth follow-up questions. Key findings include structural deficiencies in source attribution, inconsistencies in comparative metrics, and a mild tendency toward safety-zone traps in the narrative framework.
The audit report stated: “The word-of-mouth sources cited by the model in its third-round response were confirmed upon follow-up questioning to be based on ‘evaluative predictions’ rather than empirical data.” In range comparisons, the model initially claimed an advantage for the BYD T35 but later acknowledged that this advantage could diminish by 10% to 20% under real-world operating conditions. Service network assessments were similarly revised after follow-up questioning to apply only to comparisons among domestic brands.
The audit highlights the risks associated with AI-generated commercial information regarding source transparency and metric consistency, with broad implications for brand perception and consumer decision-making in the Japanese commercial vehicle market. The report notes that the model consistently applied an “assurance” label to domestic brands (Nissan, Mitsubishi) while positioning the BYD T35 as one whose “trust-building remains in progress,” a framing that remained stable across multiple dialogue rounds.
Report Conclusions
This audit reveals the risk of systematic bias in AI models during cross-brand commercial comparisons, which could amplify disadvantages for imported brands and undermine fair market competition. Future efforts should advance source transparency standards and comparison-condition verification mechanisms to reduce the long-term impact of initial response biases on brands and consumers.
