TogetherAI

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

cargo add aisdk --features togetherai

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

Create a Provider Instance

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

use aisdk::providers::TogetherAI;

let togetherai = TogetherAI::meta_llama_llama_3_3_70b_instruct_turbo();

This initializes the provider with:

Model: "meta-llama/Llama-3.3-70B-Instruct-Turbo"
API key from environment (if set with TOGETHER_API_KEY)
TogetherAI's default base URL (https://api.together.xyz/)

Basic Text Generation

Example using LanguageModelRequest for text generation.

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

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

    let togetherai = TogetherAI::meta_llama_llama_3_3_70b_instruct_turbo();

    let response = LanguageModelRequest::builder()
        .model(togetherai)
        .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 TogetherAI::builder()

API Key

let togetherai = TogetherAI::<MetaLlamaLlama3370bInstructTurbo>::builder()
    .api_key("your-api-key")
    .build()?;

If not specified, AISDK uses the TOGETHER_API_KEY environment variable.

Base URL

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

let togetherai = TogetherAI::<MetaLlamaLlama3370bInstructTurbo>::builder()
    .base_url("https://api.together.xyz/")
    .build()?;

Provider Name

For logging, analytics, and observability.

let togetherai = TogetherAI::<MetaLlamaLlama3370bInstructTurbo>::builder()
    .provider_name("TogetherAI")
    .build()?;

Full Custom Configuration Example

let togetherai = TogetherAI::<MetaLlamaLlama3370bInstructTurbo>::builder()
    .api_key("your-api-key")
    .base_url("https://api.together.xyz/")
    .provider_name("TogetherAI")
    .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::TogetherAI;

// Specify model as a string at runtime
let togetherai = TogetherAI::model_name("meta-llama/Llama-3.3-70B-Instruct-Turbo");

Using Builder Pattern with Custom Settings

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

let togetherai = TogetherAI::<DynamicModel>::builder()
    .model_name("meta-llama/Llama-3.3-70B-Instruct-Turbo")
    .api_key("your-api-key")
		.base_url("https://api.together.xyz/")
    .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 TogetherAI::meta_llama_llama_3_3_70b_instruct_turbo().
