UnverifiedThe version under test is jointly determined by the model used, model parameters, prompts, and context; a change in any one of these constitutes a change in the version under test.71% similarUnverifiedBased on the Modelfile mechanism, users can perform instruction fine-tuning or parameter adjustment on top of existing models to create customized models.71% similarUnverifiedParameterized policy updates directly modify model weights (e.g., online updating of LoRA fine-tuning layers), offering a higher capability ceiling but introducing the risk of catastrophic forgetting; non-parameterized approaches change behavior by modifying prompts, retrieved content, or tool configurations, offering strong reversibility but limited expressiveness.70% similarUnverifiedThe core logic of diff editing is to have the model output only the parts that need to be changed, in order to reduce generation volume and avoid redundant output of irrelevant code.69% similarUnverifiedDirect parameter modification methods achieve editing by locating weights associated with the target fact and performing matrix updates; they are fast but prone to degrading the model's general capabilities at scale.69% similar
