  Prompting helps guide language model behavior by adding some input text specific to a task. Prompt tuning is an additive method for only training and updating the newly added prompt tokens to a pretrained model. This way, you can use one pretrained model whose weights are frozen, and train and update a smaller set of prompt parameters for each downstream task instead of fully finetuning a
