🐘 Loyal Elephie: Your Trusty Memory-enabled AI Companion 🧠

🚀 Embark on a exciting adventure with Loyal Elephie, your faithful AI sidekick! This project combines the power of a neat Next.js web UI and a mighty Python backend, leveraging the latest advancements in Large Language Models (LLMs) and Retrieval Augmented Generation (RAG) to deliver a seamless and meaningful chatting experience! 🎉

Features

🎛️ Controllable Memory: Take control of Loyal Elephie's memory! You decide which moments to save, and you can easily edit the context as needed. It is your second-brain for episodic memory. ✍️
🔍 Hybrid Search: Experience the powerful combination of Chroma and BM25 for efficient searches! It's also optimized for handling date-based queries. 📅
🔒 Secure Web Access: With a built-in login feature, only authorized users can access your AI companion, ensuring your conversations remain private and secure over the internet. 🛡️
🤖 Streamlined LLM Agent: Loyal Elephie uses XML syntax with no function-calling required. It is also optimized for less token usage and works smoothly with great local LLMs using Llama.cpp or ExllamaV2. 💬
📝 (Optional) Markdown Editor Integration: Connect with online Markdown editors to view the original referred document during chats and experience real-time LLM knowledge integration after editing your notes online. 🌐

Loyal Elephie supports both open and proprietary LLMs and embeddings serving as OpenAI compatible APIs.

Warning: This project was originally designed for Linux and compatibility with Windows or macOS has not been fully tested. If you are using Windows, I strongly recommend you to run this project in WSL.

With SilverBulletMd, you can edit a note on the browser and then let Loyal Elephie rememeber it!

Usage Tips

use "Save" button to save the current conversation into Loyal Elephie's memory.
use "Reset" button to clear the current conversation (not affecting saving status, the same as refreshing page)
click on the titles in "Reference" to navigate to the corresponding Markdown notes (but SilverBulletMd or another web Markdown editor has to be hosted and configured).

Some of the workable local LLMs tested:

OpenHermes-2.5-Mistral-7B
Mixtral-8x7B-Instruct-v0.1
c4ai-command-r-v01
Meta-Llama-3-70B-Instruct (Best so far)
Qwen2-72b-instruct (Best for non-English languages)

For those who need hand-on local embedding API, an embedding server example is added to "external_example".
