OpenAI Rust Library

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

• Chat (including SSE streaming)
• Completions (including SSE streaming)
• Edits
• Embeddings
• Engines (Already deprecated)
• Files
• Fine-Tunes (including SSE streaming)
• Images
• Models

• Supports Microsoft Azure Endpoints

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.

# .env
OPENAI_API_KEY=sk-...
OPENAI_API_ORGANIZATION=org-...

Here's an example of initializing the library with the API key loaded from an environment variable and creating a completion:

use dotenvy::dotenv;
use rs_openai::{
    chat::{ChatCompletionMessageRequestBuilder, CreateChatRequestBuilder, Role},
    OpenAI,
};
use std::env::var;

#[tokio::main]
async fn main() -> Result<(), Box<dyn std::error::Error>> {
    dotenv().ok();
    let api_key = var("OPENAI_API_KEY").unwrap();

    let client = OpenAI::new(&OpenAI {
        api_key,
        org_id: None,
    });

    let req = CreateChatRequestBuilder::default()
        .model("gpt-3.5-turbo")
        .messages(vec![ChatCompletionMessageRequestBuilder::default()
            .role(Role::User)
            .content("To Solve LeetCode's problem 81 in Rust.")
            .build()?])
        .build()?;

    let res = client.chat().create(&req).await?;
    println!("{:?}", res);

    Ok(())
}

Stream

Like ChatGPT, we support stream mode for Create chat completion, Create completion and List fine-tune events. In these cases, tokens will be sent as data-only server-sent events as they become available. Watch the demo for the following code.

use dotenvy::dotenv;
use futures::StreamExt;
use rs_openai::{
    chat::{ChatCompletionMessageRequestBuilder, CreateChatRequestBuilder, Role},
    OpenAI,
};
use std::env::var;
use std::io::{stdout, Write};

#[tokio::main]
async fn main() -> Result<(), Box<dyn std::error::Error>> {
    dotenv().ok();
    let api_key = var("OPENAI_API_KEY").unwrap();

    let client = OpenAI::new(&OpenAI {
        api_key,
        org_id: None,
    });


    // stream mode
    let req = CreateChatRequestBuilder::default()
        .model("gpt-3.5-turbo")
        .messages(vec![ChatCompletionMessageRequestBuilder::default()
            .role(Role::User)
            .content("To Solve LeetCode's problem 81 in Rust.")
            .build()?])
        .stream(true)
        .build()?;

    let mut stream = client.chat().create_with_stream(&req).await?;

    let mut lock = stdout().lock();
    while let Some(response) = stream.next().await {
        response.unwrap().choices.iter().for_each(|choice| {
            if let Some(ref content) = choice.delta.content {
                write!(lock, "{}", content).unwrap();
            }
        });

        stdout().flush()?;
    }

    Ok(())
}
