Open-MMUnlearning: Unifying Methods and Evaluation for MLLM Unlearning

We introduce Open-MMUnlearning, an open-source, extensible framework that integrates target-model preparation, multimodal data processing, unlearning, and evaluation through shared interfaces and structured configurations.

Key points

  • As multimodal large language models (MLLMs) become more capable and widely deployed, concerns about privacy and safety have become increasingly pressing.
  • Machine unlearning offers one approach to addressing these concerns by removing designated information from trained models while preserving unrelated capabilities.
  • Using a common evaluation protocol, we compare ten representative unlearning methods.
  • We further introduce a metric meta-evaluation protocol that tests faithfulness using models with controlled exposure to target knowledge and robustness under quantization and relearning.
