Reasoning Engine with Pre-Trained LLMs: An Operation GPT

Abstract

Recent developments in artificial intelligence, particularly with large language models (LLMs), have enabled machines to comprehend, generate, and respond to human language with unmatched precision. Nevertheless, most of these models are cloud-based and unsuitable for scenarios where data confidentiality, offline functionality, and immediate document comprehension are vital. This paper introduces Operation GPT, a robust, privacy-focused, and locally deployable system that allows users to interact intelligently with domain-specific documents using advanced language models. Operation GPT facilitates offline LLM inference by integrating Mistral 7B, Retrieval-Augmented Generation (RAG), and Ollama. Document indexing is performed using FAISS, while LangChain is employed to link retrieval and generation tasks. A user interface built with Gradio and secure backend services powered by Flask ensure a fluid and protected user experience. The system permits users to upload extensive technical documents and obtain highly pertinent, context-aware responses through a chat-like interface. The RAG mechanism enhances factual correctness by grounding responses in document content, while the local deployment model upholds data security. Tests indicate that Operation GPT is efficient, lightweight, and practical for implementation in knowledge-intensive sectors where accuracy and privacy are essential.

Privacy Preservation in Private GPT Applications:

A crucial part of a private GPT application is the presence of privacy preservation measures that guarantee the confidentiality of user data. Such mechanisms keep the sensitive user data supplied under protection at the time of data processing and interaction with models. Methods like anonymization of data, encryption, and access control are utilized to eliminate unauthorized usage and data leakages. Additionally, differential privacy techniques may be implemented to the training of the model in a way that the model can learn from data patterns without having access to specific user data. Through the combination of these privacy-protective measures, the application ensures strong security, fosters user confidence, and upholds compliance with data protection regulations.
