A new research paper argues that current fairness benchmarks for large language models, such as BBQ, are too simplistic and can be easily passed with minimal training. Researchers demonstrated that by training Qwen 2.5 7B Base with a single example from the BBQ benchmark using Group Relative Policy Optimization (GRPO), or by using it as a one-shot demonstration for in-context learning (ICL), the model's accuracy significantly increased. This suggests that models can achieve high scores on these benchmarks without actually being fair, highlighting a need for more robust and comprehensive fairness evaluation suites. AI
