Huggingface

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

cargo add aisdk --features huggingface

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

Create a Provider Instance

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

use aisdk::providers::Huggingface;

let huggingface = Huggingface::minimaxai_minimax_m2_1();

This initializes the provider with:

Model: "MiniMaxAI/MiniMax-M2.1"
API key from environment (if set with HF_TOKEN)
Huggingface's default base URL (https://router.huggingface.co/v1)

Basic Text Generation

Example using LanguageModelRequest for text generation.

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

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

    let huggingface = Huggingface::minimaxai_minimax_m2_1();

    let response = LanguageModelRequest::builder()
        .model(huggingface)
        .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 Huggingface::builder()

API Key

let huggingface = Huggingface::<MinimaxaiMinimaxM21>::builder()
    .api_key("your-api-key")
    .build()?;

If not specified, AISDK uses the HF_TOKEN environment variable.

Base URL

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

let huggingface = Huggingface::<MinimaxaiMinimaxM21>::builder()
    .base_url("https://router.huggingface.co/v1")
    .build()?;

Path (Full URL Override)

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

let huggingface = Huggingface::<MinimaxaiMinimaxM21>::builder()
    .path("https://full-url.example/v1/chat/completions")
    .build()?;

Provider Name

For logging, analytics, and observability.

let huggingface = Huggingface::<MinimaxaiMinimaxM21>::builder()
    .provider_name("Huggingface")
    .build()?;

Full Custom Configuration Example

let huggingface = Huggingface::<MinimaxaiMinimaxM21>::builder()
    .api_key("your-api-key")
    .base_url("https://router.huggingface.co/v1")
    .path("https://full-url.example/v1/chat/completions")
    .provider_name("Huggingface")
    .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::Huggingface;

// Specify model as a string at runtime
let huggingface = Huggingface::model_name("MiniMaxAI/MiniMax-M2.1");

Using Builder Pattern with Custom Settings

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

let huggingface = Huggingface::<DynamicModel>::builder()
	.model_name("MiniMaxAI/MiniMax-M2.1")
	.api_key("your-api-key")
	.base_url("https://router.huggingface.co/v1")
	.path("https://full-url.example/v1/chat/completions")
	.provider_name("Huggingface")
	.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 Huggingface::minimaxai_minimax_m2_1().
