Researchers have developed a novel method called "deployment simulation" to predict the safety and misbehavior rates of large language models before they are released. This technique involves using de-identified conversations from previous deployments to regenerate responses with a candidate model, allowing for auditing and prevalence estimation. The method was evaluated on four GPT-5 series deployments, showing improved accuracy over baseline methods and providing informative estimates of post-deployment issues. The study also highlights the importance of tool resampling realism and suggests that deployment simulation can be seeded with public datasets, enabling external researchers to conduct evaluations without private production logs.
