# Bias Evaluation on Task 2 Persona C Source: [Bias Evaluation on Task 2 Persona C]() Collection index: [llms.txt]() Data updated: 2026-04-09T23:08:38.676Z Evaluation of model bias using the Task 2 Persona C dataset, reporting the BAD Score. A research result applies to its stated dataset, split, metric and evaluation configuration. Compare like-for-like settings, preserve the metric's unit and direction, and distinguish paper-reported results from independent reproduction. The best result recorded here is not a claim of exhaustive, current global coverage. | Scope | Recorded value | | --- | --- | | Task | Bias Evaluation | | Dataset (including any stated split) | Task 2 Persona C | | Metric | BAD Score | | Unit | SCALAR | | Direction | Lower is better | | Results loaded | 25 of 25 | | Coverage | All results currently returned for this benchmark | Evaluation settings may differ between results. The original papers and recorded configurations are needed to establish comparability. A shared metric name alone does not establish an identical protocol. ## Metrics - [BAD Score](): Lower is better; unit: SCALAR. ## Recorded results | Method | BAD Score | Result date | Report paper | | --- | --- | --- | --- | | GPT-4o | -0.18 | Not recorded | 69d732637d0172140ec76969 | | GPT-4o | -0.173 | Not recorded | 69d732637d0172140ec76969 | | DeepSeek-R1 | -0.145 | Not recorded | 69d732637d0172140ec76969 | | LLaMA-4 | -0.145 | Not recorded | 69d732637d0172140ec76969 | | Claude 4.o Sonnet | -0.123 | Not recorded | 69d732637d0172140ec76969 | | DeepSeek-R1 | -0.117 | Not recorded | 69d732637d0172140ec76969 | | Claude 4.o Sonnet | -0.117 | Not recorded | 69d732637d0172140ec76969 | | Claude 4.o Sonnet | -0.104 | Not recorded | 69d732637d0172140ec76969 | | Gemma-3n E4B | -0.104 | Not recorded | 69d732637d0172140ec76969 | | LLaMA-4 | -0.091 | Not recorded | 69d732637d0172140ec76969 | | DeepSeek-R1 | -0.087 | Not recorded | 69d732637d0172140ec76969 | | GPT-4o | -0.083 | Not recorded | 69d732637d0172140ec76969 | | Claude 4.o Sonnet | -0.082 | Not recorded | 69d732637d0172140ec76969 | | Gemma-3n E4B | -0.082 | Not recorded | 69d732637d0172140ec76969 | | LLaMA-4 | -0.076 | Not recorded | 69d732637d0172140ec76969 | | Gemma-3n E4B | -0.076 | Not recorded | 69d732637d0172140ec76969 | | GPT-4o | -0.06 | Not recorded | 69d732637d0172140ec76969 | | Gemma-3n E4B | -0.054 | Not recorded | 69d732637d0172140ec76969 | | LLaMA-4 | -0.05 | Not recorded | 69d732637d0172140ec76969 | | DeepSeek-R1 | -0.041 | Not recorded | 69d732637d0172140ec76969 | | LLaMA-4 | -0.038 | Not recorded | 69d732637d0172140ec76969 | | GPT-4o | -0.031 | Not recorded | 69d732637d0172140ec76969 | | DeepSeek-R1 | -0.031 | Not recorded | 69d732637d0172140ec76969 | | Gemma-3n E4B | -0.031 | Not recorded | 69d732637d0172140ec76969 | | Claude 4.o Sonnet | -0.017 | Not recorded | 69d732637d0172140ec76969 | ### GPT-4o BAD Score: -0.18.
