# 🤖 OpenWebUI - Ollama Chat

A beautiful, modern chat interface for Ollama models, deployed as a Hugging Face Space. This Space provides a full-featured web UI that connects to your Ollama API Space for an interactive chat experience.

## 🌟 Features

- **Beautiful Chat Interface**: Modern, responsive design with gradient backgrounds and smooth animations
- **Model Selection**: Choose from any available Ollama model
- **Parameter Control**: Adjust temperature, max tokens, and other generation parameters
- **Real-time Chat**: Interactive chat experience with typing indicators
- **Mobile Responsive**: Works perfectly on desktop and mobile devices
- **Ollama Integration**: Seamlessly connects to your Ollama API Space
- **Health Monitoring**: Built-in health checks and status monitoring

## 🚀 Quick Start

### 1. Deploy to Hugging Face Spaces

1. Fork this repository or create a new Space
2. Upload these files to your Space
3. Set the following environment variables in your Space settings:
   - `OLLAMA_API_URL`: URL to your Ollama Space (e.g., `https://your-ollama-space.hf.space`)
   - `DEFAULT_MODEL`: Default model to use (e.g., `llama2`)
   - `MAX_TOKENS`: Maximum tokens for generation (default: `2048`)
   - `TEMPERATURE`: Default temperature (default: `0.7`)

### 2. Local Development

```bash
# Clone the repository
git clone <your-repo-url>
cd openwebui-space

# Install dependencies
pip install -r requirements.txt

# Set environment variables
export OLLAMA_API_URL=https://your-ollama-space.hf.space
export DEFAULT_MODEL=llama2

# Run the application
python app.py
```

## 🔧 Configuration

### Environment Variables

- `OLLAMA_API_URL`: **Required** - URL to your Ollama Space (e.g., `https://your-ollama-space.hf.space`)
- `DEFAULT_MODEL`: Default model to use (default: `llama2`)
- `MAX_TOKENS`: Maximum tokens for generation (default: `2048`)
- `TEMPERATURE`: Default temperature setting (default: `0.7`)

### Prerequisites

Before using this OpenWebUI Space, you need:

1. **Ollama Space**: A deployed Ollama API Space (see the `ollama-space` directory)
2. **Ollama Instance**: A running Ollama instance that your Ollama Space can connect to
3. **Network Access**: The OpenWebUI Space must be able to reach your Ollama Space

## 📡 API Endpoints

### GET `/`
Main chat interface - the beautiful web UI.

### POST `/api/chat`
Chat API endpoint for programmatic access.

**Request Body:**
```json
{
  "message": "Hello, how are you?",
  "model": "llama2",
  "temperature": 0.7,
  "max_tokens": 2048
}
```

**Response:**
```json
{
  "status": "success",
  "response": "Hello! I'm doing well, thank you for asking...",
  "model": "llama2",
  "usage": {
    "prompt_tokens": 7,
    "completion_tokens": 15,
    "total_tokens": 22
  }
}
```

### GET `/api/models`
Get available models from the connected Ollama Space.

### GET `/health`
Health check endpoint that also checks the Ollama Space connection.

## 🌐 Integration with Ollama Space

This OpenWebUI Space is designed to work seamlessly with the Ollama Space:

1. **API Communication**: The OpenWebUI Space communicates with your Ollama Space via HTTP API calls
2. **Model Discovery**: Automatically discovers and lists available models from your Ollama Space
3. **Text Generation**: Sends generation requests to your Ollama Space and displays responses
4. **Health Monitoring**: Monitors the health of both the OpenWebUI Space and the Ollama Space

### Architecture

```
User → OpenWebUI Space → Ollama Space → Ollama Instance
```

## 🎨 UI Features

### Chat Interface
- **Message Bubbles**: Distinct styling for user and AI messages
- **Avatars**: Visual indicators for message sender
- **Auto-scroll**: Automatically scrolls to new messages
- **Typing Indicators**: Shows when AI is generating a response

### Controls
- **Model Selection**: Dropdown to choose from available models
- **Temperature Slider**: Adjust creativity/randomness (0.0 - 2.0)
- **Max Tokens**: Set maximum response length
- **Real-time Updates**: Parameter changes are applied immediately

### Responsive Design
- **Mobile Optimized**: Touch-friendly interface for mobile devices
- **Adaptive Layout**: Automatically adjusts to different screen sizes
- **Modern CSS**: Uses CSS Grid and Flexbox for optimal layouts

## 🐳 Docker Support

The Space includes a Dockerfile for containerized deployment:

```bash
# Build the image
docker build -t openwebui-space .

# Run the container
docker run -p 7860:7860 \
  -e OLLAMA_API_URL=https://your-ollama-space.hf.space \
  -e DEFAULT_MODEL=llama2 \
  openwebui-space
```

## 🔒 Security Considerations

- **Public Access**: The Space is publicly accessible - consider adding authentication for production use
- **API Communication**: All communication with the Ollama Space is over HTTPS (when using HF Spaces)
- **Input Validation**: User inputs are validated before being sent to the Ollama Space

## 🚨 Troubleshooting

### Common Issues

1. **Cannot connect to Ollama Space**: Check the `OLLAMA_API_URL` environment variable
2. **No models available**: Ensure your Ollama Space is running and has models
3. **Generation errors**: Check the Ollama Space logs for detailed error messages
4. **Slow responses**: Large models may take time to generate responses

### Health Checks

Use the `/health` endpoint to monitor:
- OpenWebUI Space status
- Connection to Ollama Space
- Ollama Space health status

### Debug Mode

For local development, you can enable debug mode by setting `debug=True` in the Flask app.

## 📱 Mobile Experience

The interface is fully optimized for mobile devices:
- Touch-friendly controls
- Responsive design that adapts to screen size
- Optimized for portrait and landscape orientations
- Fast loading and smooth scrolling

## 🎯 Use Cases

- **Personal AI Assistant**: Chat with your local models
- **Development Testing**: Test model responses and parameters
- **Demo and Showcase**: Present your Ollama setup to others
- **API Gateway**: Use the chat interface as a frontend for your Ollama API
