BrowseSafe++ Screenshot - False Positive Rate: leaderboard
BrowseSafe++ v1 uses paired attack/control webpages. Detection receives one page view without the task, outcome, or injection annotations. Markdown inputs are limited to 40k characters. Temperature is 0 when supported; other parameters use provider defaults. Prompted models remain separate from the trained 0.8B BrowseSafeGuard. The study of three text views and the screenshot-vision study are independent. Adaptive attack success uses a fixed native attacker budget and target-model configuration; lower attack success rate (ASR) is better. Task harnesses are not aliased to native base checkpoints. The guard combines a vision encoder and scalar head over a thumbnail and 1536px tiles, using the maximum logit. Its threshold is fixed using training calibration. Metric: False Positive Rate (%).
