# BrainChulo: Harnessing the Memory Power of the Camelids

BrainChulo is a powerful Chat application with an emphasis on its memory management system. Our work is inspired by the camel family's resilience and adaptability. The repository contains a custom LTM (Long-Term Memory) approach for Llama-based LLMs (Large Language Models), and is designed to help users enhance their experience when using Open-Source LLMs.

## Current Look-n-Feel

## Features

- Custom LTM implementation based on Open Source Large Language Models
- Memory retrieval algorithms for quick recall
- Easy-to-use interface for storing and managing memories
- Modern User Interface
- One-Shot, Few-Shot, and Tool-Capable Agents with Full Vector-Based Memory Integration
- Ability to handle multiple conversations
- Ability to upvote or downvote AI answers for fine-tuning

## Installation
### Oobabooga UI (not officially supported currently)
**Update 06.06.2023** As of today, we're dropping support to [Oobabooga Text Generation WebUI](https://github.com/oobabooga/text-generation-webui).The reason being is it does not offer enough support for the [guidance library](https://github.com/microsoft/guidance) features.

**Update 08.06.2023** We've raised a PR to add an extension that would enable us to again use oobabooga. If that's important for you, [leave a thumbs up](https://github.com/oobabooga/text-generation-webui/pull/2554) so it gets merged.

Note that currently, we only support models on GPU (GPTQ or Hugging Face), because the guidance does not (yet) fully support llama cpp bindings, or any GGML model.
This would be the case until [this PR is merged on guidance library](https://github.com/microsoft/guidance/pull/70).

We plan to reintroduce CPU support through GGML / llamacpp-bindings - at least for the LLaMA models - when this PR is fully merged into guidance.

### Using docker-compose
To use BrainChulo, there are four required steps.
### 1 - Install requirements (docker)

1. [Docker Engine](https://docs.docker.com/engine/)
2. [Docker Compose v2](https://docs.docker.com/compose/)
3. [nvidia-docker](https://github.com/NVIDIA/nvidia-docker)

If you want to use docker-compose v1, you might run into an issue with the port binding - though there's an easy workaround here:
https://github.com/ChuloAI/BrainChulo/issues/39

### 2 - Clone your desired model from Hugging Face

Choose a model that either implements the Hugging Face API, if you're downloading them from TheBloke, typically they have the `-HF` suffix, or a GPTQ one (`-GPTQ`)

There a couple of scripts to help you with this:
- `bootstrap_models.py`
- `download-model.py` (highly-inspired script from Oobabooga's repo)

If you simply execute `python bootstrap_models.py` it will create the required directory and download a pair of recommended models to get started. You can override the default model by passing additional arguments:

For instance, downloading WizardLM-30B-GPTQ
```bash
python bootstrap_models.py TheBloke/WizardLM-30B-GPTQ
```

Under the hood, this is roughly equivalent to this:

```bash
mkdir models
cd models
git clone https://huggingface.co/sentence-transformers/all-MiniLM-L6-v2
git clone https://huggingface.co/TheBloke/wizardLM-7B-HF
cd ..
```

### 3 - Update the environment variables
Copy the `.env.example` file. In Linux, that is done:

```bash
cp .env.example .env
```

You should then override the following variables to match your downloaded model:
```
MODEL_PATH=/models/vicuna-AlekseyKorshuk-7B-GPTQ-4bit-128g
# General Settings
GENERAL_LOADING_METHOD=GPTQ
GENERAL_BOOL_CPU_OFFLOADING=true
# HuggingFace
HF_BOOL_USE_QUANT=true
HF_BOOL_USE_4_BIT=true
# GPTQ
GPTQ_INT_WBITS=4
GPTQ_INT_GROUP_SIZE=128
GPTQ_INT_PRE_LOADED_LAYERS=20
GPTQ_DEVICE="cuda"
```
Note that you only need to set the variables according to your desired model loading method.
`GENERAL_LOADING_METHOD` expects either `GPTQ` or `HUGGING_FACE`. Most of these parameters are self-explanatory,
except `GPTQ_INT_PRE_LOADED_LAYERS` which only changes how many layers are preloaded for the `CPU OFFLOADING` when loading a GPTQ model.
Setting a number too high for the model e.g., 50 for a 7B model triggers an error.

### 4 - Download, build and start Docker containers through the docker-compose
```
docker-compose up --build
```

## Usage
### BrainChulo
#### Starting the service
The easiest way to start BrainChulo is using Docker with `docker-compose`:

```
# from the root directory of the project, start with:
docker-compose up --build

# To shut it down
docker compose down

# After pulling the latest code, make sure to run the database migrations
docker-compose exec backend alembic upgrade head
```

## Enabling Flow Agents
We have a experimental feature that enables what we call flow agents. To activate it, set the feature flag to true in the .env file:
```
USE_FLOW_AGENTS=true
```

## Creating a Plugin

1. Create a new directory for your plugin, e.g. `/app/plugins/my_plugin`

2. Inside the new directory, create a new Python module, e.g. `myplugin_main.py`

3. In `myplugin_main.py`, define your plugin routes using FastAPI. See the `/app/plugins/sample_plugin` directory for an example.

4. Create a `database.py` file to define your SQLModel models. Data for hese models will be persisted in the main database.

5. Once you have defined your models, run the following command **with your own message** to generate a new Alembic migration file. Migration files allow the application to add your models to the database schema:

```
alembic revision --autogenerate -m "Add Sample Plugin Demo Model"
```

6. Run `alembic upgrade head` to run your migration. This will update your database.

**Note:** If you wish to run these commands using the stood-up containers, prefix them as such:

```
# To create a migration
docker-compose exec backend alembic revision --autogenerate -m "Add Sample Plugin Demo Model"

# To run a migration
docker-compose exec backend alembic upgrade head
```

**Developers:** While you may use the container-based approach since it is a development container with hot reloading you may also wish to start BrainChulo's services manually. To do so, run the `main.py` script from within the `app` directory, then start the frontend:

```
cd ./app
python main.py

# if within the ./app directory
cd ../frontend
npm run dev
```

This will eventually launch the BrainChulo application. Point your web browser to the following default URL:

```
http://localhost:5173/
```

This interface allows you to chat or load text documents which will be used as context in the BrainChulo application.

### &#9888; WARNING &#9888;
As we develop BrainChulo the application is gaining abilities which allow it to access and change files on the filesystem. This is a major security risk. We strongly recommend that you run BrainChulo in a Docker container, using the provided `Dockerfile`.

To run BrainChulo in a Docker container, you just need to run:

`docker-compose up`

To shut down the container:

`docker-compose down`

## Roadmap

Here's a detailed roadmap for the BrainChulo project:

1. **Create an End-to-End capable of creating, persisting, and using an index which can be loaded as context to a conversation using `langchain memory` module or `llama-index` package.** This will allow the agent to maintain context and continuity between conversations and ensure that information is not lost over time.

2. **Implement a Long-Term Memory (LTM) mechanism using a Vector Database layer with fine-tuning/training capabilities for LTM Management.** This will allow the agent to remember past conversations and information for longer periods of time, and provide a more personalized experience to the user.

3. **Implement Tools for the agent (ability to browse the web, send a tweet, read a file, use the REPL).** These tools will enable the agent to perform various tasks and make it more versatile.

4. **Create an Integration point for external systems.** This will allow other systems to interact with the BrainChulo agent and expand its capabilities.

5. **Integrate into existing Text Generation Systems such as oobabooga and Kobold.** This will enable the BrainChulo agent to work with other text generation systems and provide a wider range of outputs to the user.

Please note that this roadmap is subject to change based on community feedback and contributions. We welcome your input and ideas as we work together to add long-term memory to custom LLMs!

## Notes for developers
More commands are available on Docker. They are not necessary but can help developers
Build the Docker image:

`docker build -t brainchulo .`

Run the Docker container:

`docker run -p 7865:7865 --name brainchulo brainchulo`

If you want hot reloading when coding, start the app with the following command:
```
gradio main.py
```
