LINE Bot Demo for Personal Data Hider and LLM Detector

This project provides a FastAPI application that integrates with LINE Bot to hide personal data and detect if customer service assistance is needed using LLM (Large Language Models). The application leverages the Gemini Pro API and Groq for generative AI capabilities.

Code Overview

Main Functionality

Message Handling: The application listens for incoming messages from LINE Bot and processes them based on their type (text or image).
Personal Data Removal: Uses a local LLM to remove personal information from text messages.
LLM Assistance Detection: Determines if a message requires customer service assistance and processes it using the Gemini Pro API.
Image Description: Describes images using the Gemini Pro API.

Key Functions

generate_gemini_text_complete(prompt): Generates a text completion using the Gemini Pro API.
generate_result_from_image(img, prompt): Generates a description for an image using the Gemini Pro API.
generate_local_llm_result(prompt): Generates a result using a local LLM (Groq).

Example

Here is an example of how the application processes a text message:

A user sends a message containing personal information.
The application uses the local LLM to remove personal information.
The modified message is then processed by the Gemini Pro API to generate a complete response in Traditional Chinese (zh-TW).
The original and modified messages are sent back to the user.
