# Deploy a local LLM

RAGFlow supports deploying models locally using Ollama or Xinference. If you have locally deployed models to leverage or wish to enable GPU or CUDA for inference acceleration, you can bind Ollama or Xinference into RAGFlow and use either of them as a local "server" for interacting with your local models.

RAGFlow seamlessly integrates with Ollama and Xinference, without the need for further environment configurations. You can use them to deploy two types of local models in RAGFlow: chat models and embedding models.

:::tip NOTE
This user guide does not intend to cover much of the installation or configuration details of Ollama or Xinference; its focus is on configurations inside RAGFlow. For the most current information, you may need to check out the official site of Ollama or Xinference.
:::

## Deploy a local model using Ollama

[Ollama](https://github.com/ollama/ollama) enables you to run open-source large language models that you deployed locally. It bundles model weights, configurations, and data into a single package, defined by a Modelfile, and optimizes setup and configurations, including GPU usage.

:::note
- For information about downloading Ollama, see [here](https://github.com/ollama/ollama?tab=readme-ov-file#ollama).
- For information about configuring Ollama server, see [here](https://github.com/ollama/ollama/blob/main/docs/faq.md#how-do-i-configure-ollama-server).
- For a complete list of supported models and variants, see the [Ollama model library](https://ollama.com/library).
:::

To deploy a local model, e.g., **Llama3**, using Ollama: 

### 1. Check firewall settings

Ensure that your host machine's firewall allows inbound connections on port 11434. For example:
   
```bash
sudo ufw allow 11434/tcp
```
### 2. Ensure Ollama is accessible

Restart system and use curl or your web browser to check if the service URL of your Ollama service at `http://localhost:11434` is accessible.
   
```bash
Ollama is running
```

### 3. Run your local model

```bash
ollama run llama3
```
<details>
  <summary>If your Ollama is installed through Docker, run the following instead:</summary>

   ```bash
   docker exec -it ollama ollama run llama3
   ```
</details>

### 4. Add Ollama

In RAGFlow, click on your logo on the top right of the page **>** **Model Providers** and add Ollama to RAGFlow: 

![add ollama](https://github.com/infiniflow/ragflow/assets/93570324/10635088-028b-4b3d-add9-5c5a6e626814)


### 5. Complete basic Ollama settings

In the popup window, complete basic settings for Ollama:

1. Because **llama3** is a chat model, choose **chat** as the model type.
2. Ensure that the model name you enter here *precisely* matches the name of the local model you are running with Ollama.
3. Ensure that the base URL you enter is accessible to RAGFlow.
4. OPTIONAL: Switch on the toggle under **Does it support Vision?** if your model includes an image-to-text model.

:::caution NOTE
- If your Ollama and RAGFlow run on the same machine, use `http://localhost:11434` as base URL.
- If your Ollama and RAGFlow run on the same machine and Ollama is in Docker, use `http://host.docker.internal:11434` as base URL. 
- If your Ollama runs on a different machine from RAGFlow, use `http://<IP_OF_OLLAMA_MACHINE>:11434` as base URL. 
:::

:::danger WARNING
If your Ollama runs on a different machine, you may also need to set the `OLLAMA_HOST` environment variable to `0.0.0.0` in **ollama.service** (Note that this is *NOT* the base URL):

```bash
Environment="OLLAMA_HOST=0.0.0.0"
```

See [this guide](https://github.com/ollama/ollama/blob/main/docs/faq.md#how-do-i-configure-ollama-server) for more information.
:::

:::caution WARNING
Improper base URL settings will trigger the following error:
```bash
Max retries exceeded with url: /api/chat (Caused by NewConnectionError('<urllib3.connection.HTTPConnection object at 0xffff98b81ff0>: Failed to establish a new connection: [Errno 111] Connection refused'))
```

### 6. Update System Model Settings

Click on your logo **>** **Model Providers** **>** **System Model Settings** to update your model: 
   
*You should now be able to find **llama3** from the dropdown list under **Chat model**.*

> If your local model is an embedding model, you should find your local model under **Embedding model**.

### 7. Update Chat Configuration

Update your chat model accordingly in **Chat Configuration**:

> If your local model is an embedding model, update it on the configruation page of your knowledge base.

## Deploy a local model using Xinference

Xorbits Inference([Xinference](https://github.com/xorbitsai/inference)) enables you to unleash the full potential of cutting-edge AI models.

:::note
- For information about installing Xinference Ollama, see [here](https://inference.readthedocs.io/en/latest/getting_started/).
- For a complete list of supported models, see the [Builtin Models](https://inference.readthedocs.io/en/latest/models/builtin/).
:::

To deploy a local model, e.g., **Llama3**, using Xinference:

### 1. Start an Xinference instance

```bash
$ xinference-local --host 0.0.0.0 --port 9997
```

### 2. Launch your local model

Launch your local model (**Mistral**), ensuring that you replace `${quantization}` with your chosen quantization method
:
```bash
$ xinference launch -u mistral --model-name mistral-v0.1 --size-in-billions 7 --model-format pytorch --quantization ${quantization}
```
### 3. Add Xinference

In RAGFlow, click on your logo on the top right of the page **>** **Model Providers** and add Xinference to RAGFlow: 

![add xinference](https://github.com/infiniflow/ragflow/assets/93570324/10635088-028b-4b3d-add9-5c5a6e626814)

### 4. Complete basic Xinference settings

Enter an accessible base URL, such as `http://<your-xinference-endpoint-domain>:9997/v1`. 

### 5. Update System Model Settings

Click on your logo **>** **Model Providers** **>** **System Model Settings** to update your model: 
   
*You should now be able to find **mistral** from the dropdown list under **Chat model**.*

> If your local model is an embedding model, you should find your local model under **Embedding model**.

### 7. Update Chat Configuration

Update your chat model accordingly in **Chat Configuration**:

> If your local model is an embedding model, update it on the configruation page of your knowledge base.
