OpenAI API client library for Rust (unofficial)

The OpenAI API client Rust library provides convenient access to the OpenAI API from Rust applications.

Check out the docs.rs.

Installation:

Cargo.toml

[dependencies]
openai-api-rs = "4.0.9"

Usage

The library needs to be configured with your account's secret key, which is available on the website. We recommend setting it as an environment variable. Here's an example of initializing the library with the API key loaded from an environment variable and creating a completion:

Set OPENAI_API_KEY to environment variable

$ export OPENAI_API_KEY=sk-xxxxxxx

Create client

let client = Client::new(env::var("OPENAI_API_KEY").unwrap().to_string());

Create request

let req = ChatCompletionRequest::new(
    GPT4.to_string(),
    vec![chat_completion::ChatCompletionMessage {
        role: chat_completion::MessageRole::user,
        content: chat_completion::Content::Text(String::from("What is bitcoin?")),
        name: None,
    }],
);

Send request

let result = client.chat_completion(req)?;
println!("Content: {:?}", result.choices[0].message.content);

Set OPENAI_API_BASE to environment variable (optional)

$ export OPENAI_API_BASE=https://api.openai.com/v1

Example of chat completion

use openai_api_rs::v1::api::Client;
use openai_api_rs::v1::chat_completion::{self, ChatCompletionRequest};
use openai_api_rs::v1::common::GPT4;
use std::env;

fn main() -> Result<(), Box<dyn std::error::Error>> {
    let client = Client::new(env::var("OPENAI_API_KEY").unwrap().to_string());

    let req = ChatCompletionRequest::new(
        GPT4.to_string(),
        vec![chat_completion::ChatCompletionMessage {
            role: chat_completion::MessageRole::user,
            content: chat_completion::Content::Text(String::from("What is bitcoin?")),
            name: None,
        }],
    );

    let result = client.chat_completion(req)?;
    println!("Content: {:?}", result.choices[0].message.content);
    println!("Response Headers: {:?}", result.headers);

    Ok(())
}
