#### Introduction
This guide explains how to use g4f to run language models locally. G4F (GPT4Free) allows you to interact with various language models on your local machine, providing a flexible and private solution for natural language processing tasks.

## Usage
 
#### Local inference
How to use g4f to run language models locally
  
#### Required dependencies
**Make sure to install the required dependencies by running:**
```bash
pip install g4f[local]
```
or
```bash
pip install -U gpt4all
```

  

#### Basic usage example 
```python
from g4f.local import LocalClient

client   = LocalClient()
response = client.chat.completions.create(
    model    = 'orca-mini-3b',
    messages = [{"role": "user", "content": "hi"}],
    stream   = True
)

for token in response:
    print(token.choices[0].delta.content or "")
```

Upon first use, there will be a prompt asking you if you wish to download the model. If you respond with `y`, g4f will go ahead and download the model for you.

You can also manually place supported models into `./g4f/local/models/`
  

**You can get a list of the current supported models by running:**
```python
from g4f.local import LocalClient

client   = LocalClient()
client.list_models()
```

#### Performance Considerations
**When running language models locally, consider the following:**
   - RAM requirements vary by model size (see the 'ram' field in the model list).
   - CPU/GPU capabilities affect inference speed.
   - Disk space is needed to store the model files.

#### Troubleshooting
**Common issues and solutions:**
   1. **Model download fails**: Check your internet connection and try again.
   2. **Out of memory error**: Choose a smaller model or increase your system's RAM.
   3. **Slow inference**: Consider using a GPU or a more powerful CPU.
