Cortecs

AISDK provides first-class support for Cortecs 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 Cortecs provider feature:

cargo add aisdk --features cortecs

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

Create a Provider Instance

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

use aisdk::providers::Cortecs;

let cortecs = Cortecs::claude_4_5_sonnet();

This initializes the provider with:

Model: "claude-4-5-sonnet"
API key from environment (if set with CORTECS_API_KEY)
Cortecs's default base URL (https://api.cortecs.ai/v1)

Basic Text Generation

Example using LanguageModelRequest for text generation.

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

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

    let cortecs = Cortecs::claude_4_5_sonnet();

    let response = LanguageModelRequest::builder()
        .model(cortecs)
        .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 Cortecs::builder()

API Key

let cortecs = Cortecs::<Claude45Sonnet>::builder()
    .api_key("your-api-key")
    .build()?;

If not specified, AISDK uses the CORTECS_API_KEY environment variable.

Base URL

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

let cortecs = Cortecs::<Claude45Sonnet>::builder()
    .base_url("https://api.cortecs.ai/v1")
    .build()?;

Path (Full URL Override)

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

let cortecs = Cortecs::<Claude45Sonnet>::builder()
    .path("https://full-url.example/v1/chat/completions")
    .build()?;

Provider Name

For logging, analytics, and observability.

let cortecs = Cortecs::<Claude45Sonnet>::builder()
    .provider_name("Cortecs")
    .build()?;

Full Custom Configuration Example

let cortecs = Cortecs::<Claude45Sonnet>::builder()
    .api_key("your-api-key")
    .base_url("https://api.cortecs.ai/v1")
    .path("https://full-url.example/v1/chat/completions")
    .provider_name("Cortecs")
    .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::Cortecs;

// Specify model as a string at runtime
let cortecs = Cortecs::model_name("claude-4-5-sonnet");

Using Builder Pattern with Custom Settings

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

let cortecs = Cortecs::<DynamicModel>::builder()
	.model_name("claude-4-5-sonnet")
	.api_key("your-api-key")
	.base_url("https://api.cortecs.ai/v1")
	.path("https://full-url.example/v1/chat/completions")
	.provider_name("Cortecs")
	.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 Cortecs::claude_4_5_sonnet().
