openai

An unofficial Rust library for the OpenAI API.

Note

The ownership of the openai package on crates.io has been transfered to me, Valentine Briese (not the previous owner). This is an entirely different project than the one that was on crates.io as openai previously!

Warning

Currently in alpha, not yet stable enough to be used in any production applications. See Implementation Progress.

Core Principles

• Instead of accessing all functions as methods on a single client-like structure, functions should be accessed from their own modules.
• Environmental variables should be the prioitized method of authentication, but you shouldn't be forced to do things this way. (Currently, you kind of are, because the API key is needed during compile-time.)
• This is a LIBRARY, not a WRAPPER! The goal here isn't to just give some basic wrapper functions for making HTTP requests, it's to "rust-ify" things. We want to create the illusion that the OpenAI API was made in Rust first!
• What is this, C? No, it's Rust! We follow the object-oriented paradigm, not the procedural one. What this mainly means is less create_completion(), more Completion::new().

Examples

I'm still working on making examples in the examples directory. If you're looking to work with the completions module, you're in luck! Because that's the only module there is an example for right now. For other modules, you can look at the tests submodules for some reference.

Examples come slowly because this project, in its current state, changes very quickly, and it's not fun making sure all examples accurately reflect the latest version. But, they are coming, don't worry!

Troubleshooting

environment variable OPENAI_KEY should be defined

An error you will likely run into, and a hopefully pretty self-explanatory one. For the library to even build, you must have an environment variabled named OPENAI_KEY which is set to, you guessed it, your OpenAI API key. Without your API key, this library can't do anything. In fact, the library won't build without it because at compile-time it uses your key to fetch all available models and generate the ModelID enumerator.

In a development environment, this can be best resolved by created a .env file in the root of your project with the following contents:

env OPENAI_KEY=put-your-api-key-here

Then, you need to load the contents of your .env file when your program starts. For this, I recommend a crate such as dotenvy.
