Overview :

CAG (Cache-Augmented Generation) is an innovative enhancement technique for language models aimed at addressing issues such as retrieval delays, errors, and complexity inherent in traditional RAG (Retrieval-Augmented Generation) methods. By preloading all relevant resources and caching their runtime parameters within the model context, CAG can generate responses directly during inference without requiring real-time retrieval. This approach significantly reduces latency, increases reliability, and simplifies system design, making it a practical and scalable alternative. As the context window of large language models (LLMs) continues to expand, CAG is expected to be applicable in more complex scenarios.

Target Users :

CAG is suitable for applications that require efficient generation of high-quality text, such as natural language processing, question-answering systems, and text summarization. For users who need quick responses with a high degree of accuracy, including researchers, developers, and enterprises, CAG offers an effective solution.

Features

Preload knowledge resources: Loads all relevant resources into the model's context, eliminating the need for real-time retrieval.

Cache runtime parameters: Stores parameters used during inference for quick response generation.

Reduce latency: Significantly increases the inference speed of the model by removing real-time retrieval steps.

Enhance reliability: Reduces retrieval errors, ensuring the relevance and accuracy of generated content.

Simplify system design: Offers an alternative that does not require retrieval, reducing the complexity of system architecture and maintenance.

Support multiple datasets: Applicable to various datasets, such as SQuAD and HotpotQA.

Flexible parameter configuration: Allows users to adjust various parameters like knowledge amount, paragraph count, and question count according to specific needs.

How to Use

1. Install dependencies: Run `pip install -r ./requirements.txt` to install the required libraries.

2. Download datasets: Use the `sh ./downloads.sh` script to download the necessary SQuAD and HotpotQA datasets.

3. Create a configuration file: Create a config file by running `cp ./.env.template ./.env` and input your required keys.

4. Use the CAG model: Execute the `python ./kvcache.py` script and configure parameters as needed, such as the knowledge cache file, dataset, and similarity calculation method.

5. Conduct experiments: Based on the configured parameters, CAG will load knowledge resources and generate the corresponding output.
