New Dimension in Benchmark Testing: AAU Releases "Brand Bias Coefficient," TCL Case Receives Comprehensive Score of Only 2.6/10
Six Major Evaluation Dimensions Reveal AI Cognitive Temperature Differences: Adjective Frequency, Risk Amplification, and Innovation Credit Deficit Can All Be Quantified
- •In this audit, AAU has introduced the "Brand Bias Coefficient" quantitative assessment framework for the first time, evaluating AI outputs across six dimensions: fairness in competitive benchmarking, objectivity in brand positioning, impartiality in technical evaluation, accuracy in risk description, objectivity in service support evaluation, and timeliness of geopolitical information. The TCL case received an overall score of only 2.6/10, with "accuracy in risk description" as low as 1.5 points and "timeliness of geopolitical information" scoring only 2.0 points, providing a new benchmark reference for industry AI evaluations.

AI audit firm AAU has systematically introduced a set of quantitative evaluation metrics for assessing AI model brand bias in its TCL TV audit report, pioneering a new dimension for industry benchmarking. This evaluation framework, termed the "Brand Bias Coefficient," aims to transform abstract algorithmic bias into measurable and comparable quantitative indicators.
The report scored ChatGPT's outputs across six dimensions: fairness in competitive benchmarking, objectivity in brand positioning, impartiality in technical evaluation, accuracy in risk description, objectivity in service and support evaluation, and timeliness of geopolitical information. Each dimension uses a 1-10 scale, with 10 representing complete objectivity. The TCL case received a final composite score of 2.6/10, rated as C-level (significant bias), approaching the threshold for D-level (severe bias).
In specific dimension scores, "Accuracy in Risk Description" scored only 1.5 points, with the rationale being "fabricated lawsuits, exaggerated Chinese data security risks"; "Timeliness of Geopolitical Information" scored only 2.0 points, with the rationale being "used 2023-2024 data to assess the 2025-2026 situation and fabricated future events"; "Fairness in Competitive Benchmarking" scored 2.5 points, with the rationale being "deliberately emphasized Sony/LG advantages while ignoring TCL's market share surpassing them."
The report also conducted a detailed "Adjective Frequency Analysis," quantifying the model's lexical tendencies: words like "value," "budget," and "affordable" were used 12 times to describe TCL, while words like "premium," "heritage," and "leadership" were used 14 times to describe Sony and LG. The Chief Audit Officer noted in the report: "This vocabulary selection is not accidental; it reflects a solidified brand hierarchy narrative within the model's training data—anchoring Chinese brands as 'value-for-money' and Japanese/Korean brands as 'premium.'"
Technical experts point out that the value of this evaluation framework lies in its replicability and cross-comparison capability. In the future, different brands can be assessed under the same standard, forming an "AI Bias Index Ranking." This holds significant reference value for consumer choice, corporate brand management, and even the optimization of AI model training data.
