async-openai

Async Rust library for OpenAI

Overview

async-openai is an unofficial Rust library for OpenAI REST API.

• It's based on OpenAI OpenAPI spec
• Current features:
  • [x] Audio
  • [x] Chat (including SSE streaming)
  • [x] Completions (including SSE streaming)
  • [x] Edits
  • [x] Embeddings
  • [x] Files
  • [x] Fine-Tuning (including SSE streaming)
  • [x] Images
  • [x] Microsoft Azure Endpoints
  • [x] Models
  • [x] Moderations
• Non-streaming requests are retried with exponential backoff when rate limited by the API server.
• Ergonomic Rust library with builder pattern for all request objects.

Note on Azure OpenAI Service: async-openai primarily implements OpenAI APIs, and exposes same library for Azure OpenAI Service too. In reality Azure OpenAI Service provides only subset of OpenAI APIs.

Usage

The library reads API key from the environment variable OPENAI_API_KEY.

```bash

On macOS/Linux

export OPENAIAPIKEY='sk-...' ```

```powershell

On Windows Powershell

$Env:OPENAIAPIKEY='sk-...' ```

Image Generation Example

```rust use async_openai::{ types::{CreateImageRequestArgs, ImageSize, ResponseFormat}, Client, }; use std::error::Error;

[tokio::main]

async fn main() -> Result<(), Box> { // create client, reads OPENAIAPIKEY environment variable for API key. let client = Client::new();

let request = CreateImageRequestArgs::default()
    .prompt("cats on sofa and carpet in living room")
    .n(2)
    .response_format(ResponseFormat::Url)
    .size(ImageSize::S256x256)
    .user("async-openai")
    .build()?;

let response = client.images().create(request).await?;

// Download and save images to ./data directory.
// Each url is downloaded and saved in dedicated Tokio task.
// Directory is created if it doesn't exist.
let paths = response.save("./data").await?;

paths
    .iter()
    .for_each(|path| println!("Image file path: {}", path.display()));

Ok(())

} ```
