Jiekou

AISDK provides first-class support for Jiekou with fully typed model APIs. Model capabilities are enforced at compile time using Rust's type system. This prevents model capability mismatches and guarantees the selected model is valid for the task (e.g. tool calling).

Installation

Enable the Jiekou provider feature:

cargo add aisdk --features jiekou

This installs AISDK with the Jiekou provider enabled. Once you have enabled the Jiekou provider, you can use all aisdk features with it.

Create a Provider Instance

To create a provider instance, call Jiekou::model_name(), where model_name is the Jiekou model you want to use. Model names are exposed as snake-case methods.

use aisdk::providers::Jiekou;

let jiekou = Jiekou::baidu_ernie_4_5_300b_a47b_paddle();

This initializes the provider with:

Model: "baidu/ernie-4.5-300b-a47b-paddle"
API key from environment (if set with JIEKOU_API_KEY)
Jiekou's default base URL (https://api.jiekou.ai/openai)

Basic Text Generation

Example using LanguageModelRequest for text generation.

use aisdk::{
    core::LanguageModelRequest,
    providers::Jiekou,
};

#[tokio::main]
async fn main() -> Result<(), Box<dyn std::error::Error>> {

    let jiekou = Jiekou::baidu_ernie_4_5_300b_a47b_paddle();

    let response = LanguageModelRequest::builder()
        .model(jiekou)
        .prompt("Write a short poem about Rust.")
        .build()
        .generate_text()
        .await?;

    println!("Response text: {:?}", response.text());
    Ok(())
}

Provider Settings

You can customize provider configuration using Jiekou::builder()

API Key

let jiekou = Jiekou::<BaiduErnie45300bA47bPaddle>::builder()
    .api_key("your-api-key")
    .build()?;

If not specified, AISDK uses the JIEKOU_API_KEY environment variable.

Base URL

Useful when routing through a proxy, gateway, or self-hosted compatible endpoint.

let jiekou = Jiekou::<BaiduErnie45300bA47bPaddle>::builder()
    .base_url("https://api.jiekou.ai/openai")
    .build()?;

Path (Full URL Override)

Use .path(...) to override the full request URL instead of only the base URL.

let jiekou = Jiekou::<BaiduErnie45300bA47bPaddle>::builder()
    .path("https://full-url.example/v1/chat/completions")
    .build()?;

Provider Name

For logging, analytics, and observability.

let jiekou = Jiekou::<BaiduErnie45300bA47bPaddle>::builder()
    .provider_name("Jiekou")
    .build()?;

Full Custom Configuration Example

let jiekou = Jiekou::<BaiduErnie45300bA47bPaddle>::builder()
    .api_key("your-api-key")
    .base_url("https://api.jiekou.ai/openai")
    .path("https://full-url.example/v1/chat/completions")
    .provider_name("Jiekou")
    .build()?;

Dynamic Model Selection

For runtime model selection (e.g., loading models from config files), use DynamicModel:

Using model_name() Method with Default Settings

use aisdk::providers::Jiekou;

// Specify model as a string at runtime
let jiekou = Jiekou::model_name("baidu/ernie-4.5-300b-a47b-paddle");

Using Builder Pattern with Custom Settings

use aisdk::{
    core::DynamicModel,
    providers::Jiekou,
};

let jiekou = Jiekou::<DynamicModel>::builder()
	.model_name("baidu/ernie-4.5-300b-a47b-paddle")
	.api_key("your-api-key")
	.base_url("https://api.jiekou.ai/openai")
	.path("https://full-url.example/v1/chat/completions")
	.provider_name("Jiekou")
	.build()?;

Warning: When using DynamicModel, model capabilities are not validated at compile time. This means there's no guarantee the model supports requested features (e.g., tool calls, structured output). For compile-time safety, use the typed methods like Jiekou::baidu_ernie_4_5_300b_a47b_paddle().
