GEMMU benchmark reshuffles MLLM unlearning leaderboard, GADiff and SCRUB lead

_vztu · x · 2026-10-17

Thread conclusion: the authors release GEMMU—139 real-world concepts models already know (people, landmarks, car brands, fruits), unseen images and questions for forget and retain sets, tuning on train splits only. Re-benchmarking 9 methods on LLaVA-1.5 and Qwen3-VL reshuffles the leaderboard: the strongest are the oldest and simplest, GADiff (2022) and SCRUB (2023), while the newest method MANU (2025) ranks 6th and 5th. Bottom line: no method solves real-world multimodal unlearning yet, and the evaluation bar needs to rise.
