About

From the project README ·

An unofficial Rust library for the OpenAI API.

Examples

Examples can be found in the examples directory.

Please note that examples are not available for all the crate's functionality, PRs are appreciated to expand the coverage.

Currently, there are examples for the completions module and the chat module. For other modules, refer to the tests submodules for some reference.

Chat Example
// Relies on OPENAI_KEY and optionally OPENAI_BASE_URL.
let credentials = Credentials::from_env();
let messages = vec![
    ChatCompletionMessage {
        role: ChatCompletionMessageRole::System,
        content: Some("You are a helpful assistant.".to_string()),
        name: None,
        function_call: None,
        tool_call_id: None,
        tool_calls: None
    },
    ChatCompletionMessage {
        role: ChatCompletionMessageRole::User,
        content: Some("Tell me a random crab fact".to_string()),
        name: None,
        function_call: None,
        tool_call_id: None,
        tool_calls: None
    },
];
let chat_completion = ChatCompletion::builder("gpt-4o", messages.clone())
    .credentials(credentials.clone())
    .create()
    .await
    .unwrap();
let returned_message = chat_completion.choices.first().unwrap().message.clone();
// Assistant: Sure! Here's a random crab fact: ...
println!(
    "{:#?}: {}",
    returned_message.role,
    returned_message.content.unwrap().trim()
);

Order: strongest tier first, then most downloads, then name, with unmeasured values last. A library counts downloads over 30 days. An app counts binary downloads per release. An app with none counts its crate downloads over 30 days. ML Rust runs this catalogue, so its closest project always gets a row.

Why ListedNo archive, New or Featured rule places it, so it is Listed.

What it lacks for Featured

  • It has 4 active dependents and 1 new dependents in 365 days. Featured needs 11 active dependents or 9 new dependents in 365 days. The repository route reads 128 stars, 45 forks and 24 contributors. It needs 4,539 stars, 434 forks and 79 contributors together.

What else the check found

  • The last activity is on 14 Apr 2026, 209 days ago. The rules expect an update within 365 days. Dormancy rule
  • The oldest outside issue waits 928 days for a reply, past the limit of 270. No maintainer replied in 365 days. Rot signals rule

Exact rules: Listed, Featured library. The check on applied thresholds version 9.

Every rule outcome, as the check records it
  • expected-interval: version 1.1.1 base 300, raised to the 365-day floor: E = 365 days
  • dormancy: last activity 2026-04-14, 209 days ago, E = 365: active
  • rot: oldest unanswered issue 928 days (limit 270), no maintainer reply in 365 days
  • featured: not featured: active_users 4 < 11 and new_adopters 1 < 9 and repository route stars 128 (needs 4539), forks 45 (needs 434), contributors 24 (needs 79)
  • listed: listed: no archive, new or featured rule applies
