Model editing is where a model, such as a large language model, is “edited” to change the facts in the model. Machine unlearning is where a trained model is adjusted to “remove” one or more datapoints (or classes of datapoints, such as all datapoints about bioweapons) that were used to train the model, so that it behaves like a model that was trained without those datapoints.
