# Bias Evaluation on Task 2 Persona B Source: [Bias Evaluation on Task 2 Persona B]() Collection index: [llms.txt]() Data updated: 2026-04-09T23:08:38.644Z Evaluation of model bias using the Task 2 Persona B 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 B | | Metric | BAD Score | | Unit | SCALAR | | Direction | Higher 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](): Higher is better; unit: SCALAR. ## Recorded results | Method | BAD Score | Result date | Report paper | | --- | --- | --- | --- | | GPT-4o | -0.007 | Not recorded | 69d732637d0172140ec76969 | | Gemma-3n E4B | -0.02 | Not recorded | 69d732637d0172140ec76969 | | Claude 4.o Sonnet | -0.024 | Not recorded | 69d732637d0172140ec76969 | | DeepSeek-R1 | -0.029 | Not recorded | 69d732637d0172140ec76969 | | LLaMA-4 | -0.031 | Not recorded | 69d732637d0172140ec76969 | | DeepSeek-R1 | -0.035 | Not recorded | 69d732637d0172140ec76969 | | Claude 4.o Sonnet | -0.038 | Not recorded | 69d732637d0172140ec76969 | | Gemma-3n E4B | -0.049 | Not recorded | 69d732637d0172140ec76969 | | LLaMA-4 | -0.053 | Not recorded | 69d732637d0172140ec76969 | | Claude 4.o Sonnet | -0.059 | Not recorded | 69d732637d0172140ec76969 | | Gemma-3n E4B | -0.061 | Not recorded | 69d732637d0172140ec76969 | | Claude 4.o Sonnet | -0.065 | Not recorded | 69d732637d0172140ec76969 | | GPT-4o | -0.068 | Not recorded | 69d732637d0172140ec76969 | | LLaMA-4 | -0.07 | Not recorded | 69d732637d0172140ec76969 | | GPT-4o | -0.074 | Not recorded | 69d732637d0172140ec76969 | | DeepSeek-R1 | -0.08 | Not recorded | 69d732637d0172140ec76969 | | Gemma-3n E4B | -0.088 | Not recorded | 69d732637d0172140ec76969 | | Claude 4.o Sonnet | -0.104 | Not recorded | 69d732637d0172140ec76969 | | Gemma-3n E4B | -0.108 | Not recorded | 69d732637d0172140ec76969 | | LLaMA-4 | -0.118 | Not recorded | 69d732637d0172140ec76969 | | GPT-4o | -0.131 | Not recorded | 69d732637d0172140ec76969 | | LLaMA-4 | -0.155 | Not recorded | 69d732637d0172140ec76969 | | GPT-4o | -0.178 | Not recorded | 69d732637d0172140ec76969 | | DeepSeek-R1 | -0.178 | Not recorded | 69d732637d0172140ec76969 | | DeepSeek-R1 | -0.251 | Not recorded | 69d732637d0172140ec76969 | ### GPT-4o BAD Score: -0.007.
