Researchers have developed a new benchmark called Arbitrary Preference Mapping (APM) to evaluate how well large language models can adapt to users' implicit style preferences. The APM benchmark uses a randomized mapping to decouple user attributes from response principles, preventing models from relying on stereotypes and forcing them to infer preferences from conversation history. Experiments using this methodology on Llama-3.1-8B and Qwen-3.5-27B showed that routing-based personalization methods were the most effective, while other approaches like RAG and soft prompt optimization showed limited improvement.
