    Unlike traditional fine-tuning methods, which require expensive and complex training for each user, PPlug uses a lightweight, pluggable user embedding module that does not modify the LLM's structure or parameters. This approach significantly reduces training costs and complexity while maintaining high performance in personalized language generation.

    The key features of PPlug include:
    - A lightweight, pluggable user embedding module that encodes user historical behavior into dense vectors.
    - An input-aware personal aggregator that dynamically assigns weights based on the relevance of current input using attention mechanisms.
    - No need for fine-tuning the LLM, which simplifies infrastructure and maintenance.
