GPT4All is an exceptional language model, designed and developed by Nomic-AI, a proficient company dedicated to natural language processing. The app uses Nomic-AI's advanced library to communicate with the cutting-edge GPT4All model, which operates locally on the user's PC, ensuring seamless and efficient communication.

If you are interested in learning more about this groundbreaking project, visit their Github repository, where you can find comprehensive information regarding the app's functionalities and technical details. Moreover, you can delve deeper into the training process and database by going through their detailed Technical report, available for download at Technical report.

One of the app's impressive features is that it allows users to send messages to the chatbot and receive instantaneous responses in real time, ensuring a seamless user experience. Additionally, the app facilitates the exportation of the entire chat history in either text or JSON format, providing greater flexibility to the users.

It's worth noting that the model has recently been launched, and it's expected to evolve across time, enabling it to become even better in the future. This web UI is designed to provide the community with easy and fully localized access to a chatbot that will continue to improve and adapt across time.

Features

Installation and running

Make sure that your CPU supports AVX2 instruction set. Without it, this application won't run out of the box. To check your CPU features, please visit the website of your CPU manufacturer for more information and look for Instruction set extension: AVX2.

Note

Default model gpt4all-lora-quantized-ggml.bin is roughly 4GB in size.

Windows 10 and 11

Automatic install

1. Open directory on your computer where you want to download/install this application (This will create new directory: /gpt4all-ui/. Make sure a folder with this name does not exist in this direcotry.)
2. Press and hold Shift on your keyboard and Right click with your mouse inside a folder. Select from a menu Open Terminal or Open to powershell windows here (This command can hide under Show more options in Windows 11).

On Linux/MacOS, if you have issues, refer to the details presented here These scripts will create a Python virtual environment and install the required dependencies. It will also download the models and install them.

Docker Compose

Make sure to put models the inside the models directory. After that, you can simply use docker-compose or podman-compose to build and start the application:

Build

docker compose -f docker-compose.yml build

Start

docker compose -f docker-compose.yml up

Stop Ctrl + C

Start detached (runs in background)

docker compose -f docker-compose.yml up -d

Stop detached (one that runs in background)

docker compose stop

After that, you can open the application in your browser on http://localhost:9600

Now you're ready to work!

Supported models

You can also refuse to download the model during the install procedure and download it manually.

For now, we support ggml models that work "out-of-the-box" (tested on Windows 11 and Ubuntu 22.04.2), such as:

• GPT4ALL 7B or visit repository
• GPT4ALL 7B unfiltered or visit repository
• Vicuna 7B rev 1 or visit repository
• Vicuna 13B rev 1 or visit repository

These models don't work "out-of-the-box" and need to be converted to the right ggml type:

• Vicuna 7B or visit repository
• Vicuna 13B q4 v0 or visit repository
• Vicuna 13B q4 v1 or visit repository
• ALPACA 7B or visit repository

Just download the model into the models folder and start using the tool.

Build custom personalities and share them

To build a new personality, create a new file with the name of the personality inside the personalities folder. You can look at gpt4all_chatbot.yaml file as an example. Then you can fill the fields with the description, conditionning, etc. of your personality. Then save the file.

You can launch the application using the personality in two ways:

• Change it permanently by putting the name of the personality inside your configuration file
• Use the --personality or -p option to give the personality name to be used

If you deem your personality worthy of sharing, you can share the it by adding it to the GPT4all personalities repository. Just fork the repo, add your file, and do a pull request.

Advanced Usage

If you want more control on your launch, you can activate your environment:

On Windows:

env/Scripts/activate.bat

On Linux/MacOs:

source venv/bin/activate

Now you are ready to customize your Bot.

To run the Flask server, execute the following command:

python app.py [--config CONFIG] [--personality PERSONALITY] [--port PORT] [--host HOST] [--temp TEMP] [--n_threads N_THREADS] [--n_predict N_PREDICT] [--top_k TOP_K] [--top_p TOP_P] [--repeat_penalty REPEAT_PENALTY] [--repeat_last_n REPEAT_LAST_N] [--ctx_size CTX_SIZE]

On Linux/MacOS more details can be found here

Options

• --config: the configuration file to be used. It contains default configurations. The script parameters will override the configurations inside the configuration file. It must be placed in configs folder (default: default.yaml)
• --personality: the personality file name. It contains the definition of the pezrsonality of the chatbot and should be placed in personalities folder. The default personality is gpt4all_chatbot.yaml
• --model: the name of the model to be used. The model should be placed in models folder (default: gpt4all-lora-quantized.bin)
• --seed: the random seed for reproductibility. If fixed, it is possible to reproduce the outputs exactly (default: random)
• --port: the port on which to run the server (default: 9600)
• --host: the host address at which to run the server (default: localhost). To expose application to local network, set this to 0.0.0.0.
• --temp: the sampling temperature for the model (default: 0.1)
• --n_threads: the number of threads to be used (default:8)
• --n-predict: the number of tokens to predict at a time (default: 128)
• --top-k: the number of top-k candidates to consider for sampling (default: 40)
• --top-p: the cumulative probability threshold for top-p sampling (default: 0.90)
• --repeat-penalty: the penalty to apply for repeated n-grams (default: 1.3)
• --repeat-last-n: the number of tokens to use for detecting repeated n-grams (default: 64)
• --ctx-size: the maximum context size to use for generating responses (default: 2048)

Note: All options are optional and have default values.

Once the server is running, open your web browser and navigate to http://localhost:9600 (or http://your host name:your port number if you have selected different values for those) to access the chatbot UI. To use the app, open a web browser and navigate to this URL.

Make sure to adjust the default values and descriptions of the options to match your specific application.

Future Plans

Here are some of the future plans for this project:

Enhanced control of chatbot parameters: We plan to improve the UI of the chatbot to allow users to control the parameters of the chatbot such as temperature and other variables. This will give users more control over the chatbot's responses, and allow for a more customized experience.

Extension system for plugins: We are also working on an extension system that will allow developers to create plugins for the chatbot. These plugins will be able to add new features and capabilities to the chatbot, and allow for greater customization of the chatbot's behavior.

Enhanced UI with themes and skins: Additionally, we plan to enhance the UI of the chatbot to allow for themes and skins. This will allow users to personalize the appearance of the chatbot and make it more visually appealing.

We are excited about these future plans for the project and look forward to implementing them in the near future. Stay tuned for updates!
