# TabbyAPI
|
|
|
|
A FastAPI based application that allows for generating text using an LLM (large language model) using the [exllamav2 backend](https://github.com/turboderp/exllamav2).
|
|
|
|
## Disclaimer
|
|
|
|
This API is still in the alpha phase. There may be bugs and changes down the line. Please be aware that you might need to reinstall dependencies if needed.
|
|
|
|
## Prerequisites
|
|
|
|
To get started, make sure you have the following installed on your system:
|
|
|
|
- Python 3.x (preferably 3.11) with pip
|
|
|
|
- CUDA 12.1 or 11.8
|
|
|
|
NOTE: For Flash Attention 2 to work on Windows, CUDA 12.1 **must** be installed!
|
|
|
|
## Installing
|
|
|
|
1. Clone this repository to your machine: `git clone https://github.com/theroyallab/tabbyAPI`
|
|
|
|
2. Navigate to the project directory: `cd tabbyAPI`
|
|
|
|
3. Create a virtual environment:
|
|
|
|
1. `python -m venv venv`
|
|
|
|
2. On Windows: `.\venv\Scripts\activate`. On Linux: `source venv/bin/activate`
|
|
|
|
4. Install torch using the instructions found [here](https://pytorch.org/get-started/locally/)
|
|
|
|
5. Install an exllamav2 wheel from [here](https://github.com/turboderp/exllamav2/releases):
|
|
|
|
1. Find the version that corresponds with your cuda and python version. For example, a wheel with `cu121` and `cp311` corresponds to CUDA 12.1 and python 3.11
|
|
|
|
6. Install the other requirements via: `pip install -r requirements.txt`
|
|
|
|
## Configuration
|
|
|
|
Copy over `config_sample.yml` to `config.yml`. All the fields are commented, so make sure to read the descriptions and comment out or remove fields that you don't need.
|
|
|
|
## Launching the Application
|
|
|
|
1. Make sure you are in the project directory and entered into the venv
|
|
|
|
2. Run the tabbyAPI application: `python main.py`
|
|
|
|
## API Documentation
|
|
|
|
Docs can be accessed once you launch the API at `http://<your-IP>:<your-port>/docs`
|
|
|
|
If you use the default YAML config, it's accessible at `http://localhost:5000/docs`
|
|
|
|
## Authentication
|
|
|
|
TabbyAPI uses an API key and admin key to authenticate a user's request. On first launch of the API, a file called `api_tokens.yml` will be generated with fields for the admin and API keys.
|
|
|
|
If you feel that the keys have been compromised, delete `api_tokens.yml` and the API will generate new keys for you.
|
|
|
|
API keys and admin keys can be provided via:
|
|
|
|
- `x-api-key` and `x-admin-key` respectively
|
|
|
|
- `Authorization` with the `Bearer ` prefix
|
|
|
|
DO NOT share your admin key unless you want someone else to load/unload a model from your system!
|
|
|
|
#### Authentication Requrirements
|
|
|
|
All routes require an API key except for the following which require an **admin** key
|
|
|
|
- `/v1/model/load`
|
|
|
|
- `/v1/model/unload`
|
|
|
|
