About EasyEdit

EasyEdit is an open-source, easy-to-use knowledge editing framework for large language models (LLMs), developed by the ZJUNLP team. It supports a wide range of editing methods including parameter-modifying techniques (e.g., ROME, MEMIT, FT-L) and parameter-free approaches like IKE. The framework enables knowledge insertion, update, and erasure, and also provides real-time steering of LLM behavior during inference (EasyEdit 2.0). It includes a unified API, evaluation benchmarks (e.g., KnowEdit), multimodal editing capabilities, and integration with popular libraries like Transformers and vLLM. Designed for researchers and developers, EasyEdit simplifies the process of modifying and controlling what LLMs know and do without requiring retraining.
