OpenAi Api Unity

A simple OpenAI API wrapper for Unity

This is a community library. I am not officially affiliated with OpenAi.

Big shout out to:

• @OkGoDoIt: This code base is heavily based on the OpenAI-API-dotnet Repo, which is a dotnet wrapper for the OpenAI Api
• @ivomarel: For the OpenAI_Unity Repo

Overview

This is a simple OpenAI API wrapper that implements the API calls found in the OpenAI Api Reference as Coroutines and Async functions.

The syntax follows the docs as closely as possible. For example, the API call Create Completion at the endpoint https://api.openai.com/v1/engines/{engine_id}/completions is called using OpenAiApiV1.Engines.Engine("<engine_id>").Completions.CreateCompletionCoroutine. The API call Chat Completion at the endpoint https://api.openai.com/v1/chat/completions is called using OpenAiApiV1.Chat.Completions.CreateChatCompletionCoroutine.

To learn more:

1. Read the Quick Start section below to see a basic example of how to use the wrapper
2. Refer to the Documentation for a more detailed explanation of the library

What is and isn't tested

I've tested the list below. Testing for all other use cases will come with time

• Editor scripts and editor windows using async versions of API calls
• Coroutine api calls in Play Mode
  • I have not tested builds, but should work since it's really just Native C#. Any issues will likely be platform related.
• Unit Tested basic use cases and any issue I found along the way, to ensure stability
• Only tested on a Windows machine. If Linux/Mac authentication doesn't work as expected, please let me know.
• I do not have an organization, I have not been able to test the organization key functionality during authentication

Quick Start

See video: https://youtu.be/Ju-i0sxsX7E

Install

Unity Package Manager (Recommended): Go to the Unity Package Manager (Window > Package Manager), and click the + icon in the top left hand corner. Choose Add package from git URL... and provide the url https://github.com/hexthedev/OpenAi-Api-Unity.git.

Unity Package: Go to https://github.com/hexthedev/OpenAi-Api-Unity/releases and download the desired release. Once downloaded, open the file and follow the instructions to import it into Unity.

Git Submodule: For more advanced git users, you can simply add this repo as a submodule in your assets folder. This is especially useful if you want to edit, change and version the OpenAi Api Unity code.

Authenticate

Add a file to the path ~/.openai/auth.json (Linux/Mac) or %USERPROFILE%/.openai/auth.json (Windows)

if you only have an API key, the auth.json should look like this

{
  "private_api_key":"<YOUR_KEY>"
}

If you have an organization key, the auth.json should look like this

{
  "private_api_key":"<YOUR_KEY>",
  "organization":"<YOUR_ORGANIZATION_ID>"
}

Editor Script

To see an example of a completion in an editor script:

• From the top bar to to OpenAi > Examples > Completion In Editor Window.
• To see the code, Click the Code reference at the top of the window.

Play Script

To see an example of a completion at Runtime:

• If you're working on a scene, save the scene you are working on
• From the top bar click OpenAi > Examples > Completion At Runtime
• Look at the CompletionExample object in the hierarchy and check out the code in ExampleOpenAiApiRuntime
• Press play and run the scene

To see an example of chat completion at Runtime:

• If you're working on a scene, save the scene you are working on
• From the top bar click OpenAi > Examples > Chat At Runtime
• Look at the ChatCompletionExample object in the hierarchy and check out the code in ExampleChatRuntime
• Press play and run the scene

What Next

The above quick start is an extremely simple way to use the OpenAi Api Unity library. For more advanced use cases, refer to the OpenAi Api Unity Documentation
