  the prompt tokens are only added to the input instead of adding them to every layer of the model
  introducing anchor tokens can improve performance because they indicate characteristics of a component in the input sequence
  The results suggest that P-tuning is more efficient than manually crafting prompts, and it enables GPT-like models to compete with BERT-like models on NLU tasks.
