# NVIDIA NIM

> LLM service implementation using NVIDIA's NIM (NVIDIA Inference Microservice) API with OpenAI-compatible interface

## Overview

`NvidiaLLMService` provides access to NVIDIA's NIM language models through an OpenAI-compatible interface. It inherits from `OpenAILLMService` and supports streaming responses, function calling, and context management, with special handling for NVIDIA's incremental token reporting and enterprise deployment.

## Installation

To use NVIDIA NIM services, install the required dependencies:

```bash theme={null}
pip install "pipecat-ai[nvidia]"
```

## Prerequisites

### NVIDIA NIM Setup

Before using NVIDIA NIM LLM services, you need:

1. **NVIDIA Developer Account**: Sign up at [NVIDIA Developer Portal](https://developer.nvidia.com/)
2. **API Key**: Generate an NVIDIA API key for NIM services
3. **Model Selection**: Choose from available NIM-hosted models
4. **Enterprise Setup**: Configure NIM for on-premises deployment if needed

### Required Environment Variables

* `NVIDIA_API_KEY`: Your NVIDIA API key for authentication

## Configuration

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

<ParamField path="base_url" type="str" default="https://integrate.api.nvidia.com/v1">
  Base URL for NIM API endpoint.
</ParamField>

<ParamField path="model" type="str" default="None" deprecated>
  Model identifier to use.

  *Deprecated in v0.0.105. Use `settings=NvidiaLLMService.Settings(model=...)` instead.*
</ParamField>

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

### Settings

Runtime-configurable settings passed via the `settings` constructor argument using `NvidiaLLMService.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.nvidia import NvidiaLLMService

llm = NvidiaLLMService(
    api_key=os.getenv("NVIDIA_API_KEY"),
    model="nvidia/llama-3.1-nemotron-70b-instruct",
)
```

### With Custom Settings

```python theme={null}
from pipecat.services.nvidia import NvidiaLLMService

llm = NvidiaLLMService(
    api_key=os.getenv("NVIDIA_API_KEY"),
    settings=NvidiaLLMService.Settings(
        model="nvidia/llama-3.1-nemotron-70b-instruct",
        temperature=0.7,
        top_p=0.9,
        max_completion_tokens=1024,
    ),
)
```

## Notes

* NVIDIA NIM uses incremental token reporting. The service accumulates token usage metrics during processing and reports the final totals at the end of each request.
* The legacy `NimLLMService` import from `pipecat.services.nim` is deprecated. Use `NvidiaLLMService` from `pipecat.services.nvidia` instead.
* NIM supports both cloud-hosted and on-premises deployments. For on-premises, override the `base_url` to point to your local NIM endpoint.

<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.
