# Together AI

> LLM service implementation using Together AI's API with OpenAI-compatible interface

## Overview

`TogetherLLMService` provides access to Together AI's language models, including Meta's Llama 3.1 and 3.2 models, through an OpenAI-compatible interface. It inherits from `OpenAILLMService` and supports streaming responses, function calling, and context management with optimized open-source model hosting.

## Installation

To use Together AI services, install the required dependencies:

```bash theme={null}
uv add "pipecat-ai[together]"
```

## Prerequisites

### Together AI Account Setup

Before using Together AI LLM services, you need:

1. **Together AI Account**: Sign up at [Together AI](https://together.ai/)
2. **API Key**: Generate an API key from your account dashboard
3. **Model Selection**: Choose from available open-source models (Llama, Mistral, etc.)

### Required Environment Variables

* `TOGETHER_API_KEY`: Your Together AI API key for authentication

## Configuration

<ParamField path="api_key" type="str" required>
  Together AI API key for authentication.
</ParamField>

<ParamField path="base_url" type="str" default="https://api.together.xyz/v1">
  Base URL for Together AI API endpoint.
</ParamField>

<ParamField path="model" type="str" default="None" deprecated>
  *Deprecated in v0.0.105. Use `settings=TogetherLLMService.Settings(model=...)`
  instead.*
</ParamField>

<ParamField path="settings" type="TogetherLLMService.Settings" default="None">
  Runtime-configurable settings. See [Settings](#settings) below.
</ParamField>

### Settings

Runtime-configurable settings passed via the `settings` constructor argument using `TogetherLLMService.Settings(...)`. These can be updated mid-conversation with `LLMUpdateSettingsFrame`. See [Service Settings](/pipecat/fundamentals/service-settings) for details.

This service uses the same settings as `OpenAILLMService`. See [OpenAI LLM Settings](/api-reference/server/services/llm/openai#settings) for the full parameter reference.

## Usage

### Basic Setup

```python theme={null}
import os
from pipecat.services.together import TogetherLLMService

llm = TogetherLLMService(
    api_key=os.getenv("TOGETHER_API_KEY"),
    model="meta-llama/Meta-Llama-3.1-8B-Instruct-Turbo",
)
```

### With Custom Settings

```python theme={null}
from pipecat.services.together import TogetherLLMService

llm = TogetherLLMService(
    api_key=os.getenv("TOGETHER_API_KEY"),
    settings=TogetherLLMService.Settings(
        model="meta-llama/Meta-Llama-3.1-8B-Instruct-Turbo",
        temperature=0.7,
        top_p=0.9,
        max_completion_tokens=1024,
    ),
)
```

## Notes

* Together AI hosts a wide variety of open-source models. Model identifiers use the `organization/model-name` format.
* Together AI fully supports the OpenAI-compatible parameter set inherited from `OpenAILLMService`.

<Tip>
  The `InputParams` / `params=` pattern is deprecated as of v0.0.105. Use
  `Settings` / `settings=` instead. See the [Service Settings
  guide](/pipecat/fundamentals/service-settings) for migration details.
