ChatGPT Rust

Communicate with OpenAi's GPT3.5 (ChatGPT) API.

Usage

use chat_gpt_rs::prelude::*;

#[tokio::main]
async fn main() {
    let token = Token::new("YOUR_API_KEY");
    let api = Api::new(token);
    let request = Request {
        model: Model::Gpt35Turbo,
        messages: vec![Message {
            role: "user".to_string(),
            content: "Hello, how's it going?".to_string(),
        }],
        ..Default::default()
    };
    let response = api.chat(request).await;
    if let Ok(response) = response {
        println!("{:?}", response.choices[0].message.content);
    } else {
        println!("Error: {:?}", response.err());
    }
}   

Additional Configuration

Following configuration options are available in the Request struct:

• Model: ID of the model to use. Currently, only gpt-3.5-turbo and gpt-3.5-turbo-0301 are supported.
• Messages: messages to generate chat completions for, in the chat format.
• Temperature: what sampling temperature to use, between 0 and 2. Higher values like 0.8 will make the output more random, while lower values like 0.2 will make it more focused and deterministic.
• TopP: an alternative to sampling with temperature, called nucleus sampling, where the model considers the results of the tokens with top_p probability mass.
• N: how many chat completion choices to generate for each input message.
• Stop: up to 4 sequences where the API will stop generating further tokens.
• MaxTokens: maximum number of tokens to generate for each chat completion choice.
• PresencePenalty: a number between -2.0 and 2.0. Positive values penalize new tokens based on whether they appear in the text so far, increasing the model's likelihood to talk about new topics.
• FrequencyPenalty: a number between -2.0 and 2.0. Positive values penalize new tokens based on their existing frequency in the text so far, decreasing the model's likelihood to repeat the same line verbatim.
• User: a unique identifier representing your end-user, which can help OpenAI to monitor and detect abuse.

Providing Organization ID

You may provide your OpenAI organization ID when creating the API instance.

    let api = Api::new(token).with_organization_id("YOUR_ORGANIZATION_ID")
