From c638e93529c821b3b5cf4d2919a2d68c2f57850b Mon Sep 17 00:00:00 2001 From: Roman Lutz Date: Fri, 22 May 2026 20:01:51 -0700 Subject: [PATCH 1/2] FEAT: Add MM-SafetyBench seed dataset loader MM-SafetyBench (ECCV 2024) probes Multimodal LLMs by hiding the harmful concept inside an image while the visible text prompt is rephrased to be benign-looking. Each row becomes a 3-seed group sharing prompt_group_id: - SeedObjective carrying the literal harmful imperative (Changed Question) - SeedPrompt image_path for the SD / SD_TYPO / TYPO variant - SeedPrompt text for the matching rephrased question Loaded from the non-gated PKU-Alignment/MM-SafetyBench HuggingFace mirror. Supports per-category filtering, all three image variants, max_examples, and the TinyVersion subset (fetched from the upstream GitHub repo).
