  This repository provides the official implementation of P-tuning v2, an optimized deep prompt tuning strategy that achieves performance comparable to full fine-tuning for efficiently adapting large pre-trained language models to various downstream tasks by tuning only a small number of parameters. P-tuning v2 differentiates itself by applying multi-layer prompt tuning across multiple transformer layers using a reparameterization to generate these prompts, offering improved stability and performance, especially for small models and hard tasks.
