DeepSeek-V4-Pro is a powerhouse model, and integrating it into your local OpenClaude workspace can supercharge your AI workflows. Thanks to [NVIDIA](https://technosports.co.in/tag/nvidia/) NIM (NVIDIA Inference Microservices), you can access an OpenAI-compatible endpoint for DeepSeek models—often utilising [NVIDIA’s](https://technosports.co.in/tag/nvidia/) free developer credits or open-access tiers—directly within OpenClaude.

Here is the exact setup process to get `deepseek-ai/deepseek-v4-pro` running in your environment.

## Prerequisites

- **[OpenClaude](https://github.com/Gitlawb/openclaude)** installed and running on your machine.
- An **NVIDIA Developer account** to generate your API key.

## Step 1: Generate Your NVIDIA API Key

To route OpenClaude through NVIDIA’s servers, you need an API key from their integration platform.

1. Head over to the [NVIDIA API Catalog](https://build.nvidia.com/) (or the `integrate.api.nvidia.com` dashboard).
2. Find the **DeepSeek-V4-Pro** model in the catalogue.
3. Click on **Get API Key** (or generate one from your account settings).
4. Copy this key (it usually starts with `nvapi-` or is a long alphanumeric string like the one in your terminal). Keep it secure.

## Step 2: Configure Your OpenClaude Settings

OpenClaude allows you to define custom model providers by editing your configuration files (typically `settings.json` or your environment config). You will need to map the NVIDIA NIM endpoint and supply your API key.

Open your `settings.json` file and locate the `"customModelProviders"` section. Add the NVIDIA NIM configuration like this, or you can ask your AI to do it for you as well:

JSON

```
{
  "customModelProviders": {
    "nvidia-nim": {
      "baseUrl": "https://integrate.api.nvidia.com/v1",
      "apiKey": "YOUR_NVIDIA_API_KEY",
      "models": {
        "deepseek-v4-pro": "deepseek-ai/deepseek-v4-pro"
      }
    }
  }
}
```

*Note: Make sure to replace `"YOUR_NVIDIA_API_KEY"` with the actual key you generated in Step 1.*

## Step 3: Configure Agent Routing (If using Agent Models)

If you are utilizing OpenClaude’s agent capabilities and want to set DeepSeek-V4-Pro as the default brain for your automated tasks, you need to update the `"agentModels"` and `"agentRouting"` configuration.

Add or update the following block in your configuration:

JSON

```
{
  "agentModels": {
    "nvidia-deepseek": {
      "base_url": "https://integrate.api.nvidia.com/v1",
      "api_key": "YOUR_NVIDIA_API_KEY"
    }
  },
  "agentRouting": {
    "default": "nvidia-deepseek"
  }
}
```

### What This Does:

- **`base_url`**: Points OpenClaude away from default Anthropic/OpenAI servers and directly to NVIDIA’s high-performance API endpoint.
- **`agentRouting`**: Ensures that any default agent prompt is automatically routed through the DeepSeek model hosted on NVIDIA NIM.

## Step 4: Verify the Connection

Once your JSON files are saved, restart OpenClaude. You can verify the connection is working by initiating a chat or checking the terminal output. Under the hood, OpenClaude will now format its requests to match NVIDIA’s endpoint requirements, allowing you to use DeepSeek-V4-Pro with full configuration controls (like `temperature`, `top_p`, and high `max_tokens` limits).

You are now fully set up to leverage DeepSeek’s advanced reasoning capabilities within your custom OpenClaude environment!
