A new research paper evaluates prompt injection detection methods for large language models, highlighting that current approaches are often tested in limited settings that don't reflect real-world deployment constraints. The study introduces interpretable structural signals to capture various evasion patterns and finds that detection performance is highly dependent on the specific operational regime and threshold settings. While transformer-based models show the strongest overall performance, structural signals offer consistent, albeit modest, improvements in certain scenarios, emphasizing the need for deployment-aware evaluation.
