12 | ## Introduction
13 | CoPS dynamically synthesizes visually conditioned prompts to fine‑tune CLIP, achieving SOTA zero‑shot anomaly detection.
14 | The source code and model checkpoints for CoPS will be released upon the paper’s acceptance. Stay tuned.
15 | Here, we present a brief summary of CoPS's performance across 5 industrial and 8 medical datasets:
