While developing an AI tool to help hiring managers prepare for interviews, we stumbled upon what seems to be a novel method for detecting bias in Large Language Models.<p>By comparing how LLMs (Claude, GPT-4, Gemini, Llama) interpret anonymized vs. non-anonymized versions of the same content, we can measure and quantify bias reduction. The interesting part is that this technique could potentially be used to audit bias in any LLM-based application, not just recruitment.<p>Some key findings:<p>- Different LLMs show varying levels of bias reduction with anonymization<p>- Llama 3.1 showed consistently lower bias levels<p>- GPT-4 performed better in specific tasks like interview question generation<p>We've published our methodology and findings on arXiv: <a href="https://arxiv.org/abs/2410.16927" rel="nofollow">https://arxiv.org/abs/2410.16927</a><p>We're a boutique AI consultancy, and this research emerged from our work on building practical AI tools. Happy to discuss the technical implementation, methodology, or real-world applications.
