simple-one-api: Various large models accessible through a standardized OpenAI API format, ready to use out of the box

Introduction

There are an increasing number of free large-scale models available on the market, and one-api can be somewhat cumbersome for personal use. What's desired is an adaptation program that does not require accounting, traffic, billing, etc.

Another point is that even though some manufacturers claim compatibility with the openai interface, there are still some differences in reality!!!

simple-one-api mainly addresses the above two points, aiming to be compatible with various large model interfaces and uniformly providing the OpenAI interface. Through this project, users can easily integrate and call various large models, simplifying the complexity brought by different platform interface differences.

Features

Text Generation

Support for multiple large models:

• OpenAI ChatGPT series models

  • OpenAI
  • Cloudflare Workers AI
  • Azure OpenAI
  • Groq

• ByteDance Coze

  • Coze.com

If compatible with the OpenAI interface, it can be used directly. See the document [docs/Compatibility with OpenAI Model Protocol

Integration Guide.md](docs/Compatibility with OpenAI Model Protocol Integration Guide.md)

Supported Features

• Support for configuring multiple models, can balance load randomly
• Support for configuring multiple api_key for a model, and can balance load randomly
• Support for setting a global api_key
• Support for random model, automatically finds a configured available model
• Support for setting aliases for models
• Support for setting the service address for each model service
• Compatible with OpenAI's interface, supports both /v1 and /v1/chat/completions paths
• For models not supporting 'system', simple-one-api will include it in the first prompt for uniformity (e.g., in immersive translation, models not supporting 'system' can also be called normally)
• Support for global proxy mode
• Support for setting qps or qpm or concurrency for each service

Installation

Source Installation

1. Clone this repository:

git clone https://github.com/fruitbars/simple-one-api.git

Quick Compilation and Usage

First, ensure you have installed Go, version should be 1.18 or above, refer to the official tutorial for installation: https://go.dev/doc/install You can check the Go version with go version.

linux/macOS

chmod +x quick_build.sh
./quick_build.sh

This will generate simple-one-api in the current directory.

Windows Double-click quick_build.bat to execute.

quick_build.bat

This will generate simple-one-api.exe in the current directory.

Cross-compile for different platforms

Sometimes you need to compile versions for different platforms, such as windows, linux, macOS; after installing Go, execute build.sh

chmod +x build.sh
./build.sh

This will automatically compile executable files for the above three platforms in different architectures, generated in the build directory.

Next, configure your model services and credentials: Add your model service and credential information in the config.json file, refer to the configuration file description below.

Direct Download

Go to Releases Page

How to Use

Direct Start

Default to read and start the config.json in the same directory as simple-one-api

./simple-one-api

If you want to specify the path of config.json, you can start like this

./simple-one-api /path/to/config.json

Docker Start

Here are the steps to deploy simple-one-api using Docker: Running Run the Docker container using the following command while mounting your configuration file config.json:

docker run -d --name simple-one-api -p 9090:9090 -v /path/to/config.json:/app/config.json fruitbars/simple-one-api

Note: Make sure to replace /path/to/config.json with the absolute path of the config.json file on your host.

View Container Logs You can view the log output of the container with the following command:

docker logs -f simple-one-api

or

docker logs -f <container_id>

Where <container_id> is the container ID, which can be viewed using the docker ps command.

Docker Compose Start Steps

1. Configuration File: In docker-compose.yml, first make sure you have replaced the path of your config.json file with the correct absolute path.

2. Start Container: Using Docker Compose to start the service, you can run the following command in the directory containing docker-compose.yml:

   docker-compose up -d
   

   This command will start the simple-one-api service in the background.

Other command references can be found in the docker-compose documentation.

Other Start Methods

Other start methods:

• nohup Start
• systemd Start

Calling the API

Now, you can call your configured large model services through the OpenAI compatible interface. Service address: http://host:port/v1, api-key can be set arbitrarily

Supported model names set to random, the backend will automatically find a model marked "enabled": true to use.
