🚀 Quick Start

Installation

pip install chatlite

Basic Usage

import chatlite

# Start a simple chat server with Llama 3.2
chatlite.local_llama3p2()

# Or use Qwen 2.5
chatlite.local_qwen2p5()

# Custom configuration
server = chatlite.create_server(
    model_type="local",
    model_name="llama3.2:latest",
    temperature=0.7,
    max_tokens=4000
)
server.run()

Pre-configured Models

ChatLite comes with several pre-configured models:

# Use different models directly
from chatlite import mistral_7b_v3, mixtral_8x7b, qwen_72b

# Start Mistral 7B server
mistral_7b_v3()

# Start Mixtral 8x7B server
mixtral_8x7b()

# Start Qwen 72B server
qwen_72b()

💻 Frontend Integration

ChatLite includes a Flutter-based frontend that can be easily customized. Here's a basic example of connecting to the ChatLite server:

final channel = WebSocketChannel.connect(
  Uri.parse('ws://localhost:8143/ws/$clientId'),
);

// Send message
channel.sink.add(json.encode({
  'message': 'Hello!',
  'model': 'llama3.2:latest',
  'system_prompt': 'You are a helpful assistant',
  'agent_type': 'WebSearchAgent',
  'is_websearch_chat': true
}));

// Listen for responses
channel.stream.listen(
  (message) {
    final data = jsonDecode(message);
    if (data['type'] == 'stream') {
      print(data['message']);
    }
  },
  onError: (error) => print('Error: $error'),
  onDone: () => print('Connection closed'),
);

🔧 Configuration

ChatLite supports various configuration options:

from chatlite import create_server

server = create_server(
    model_type="local",          # local, huggingface, etc.
    model_name="llama3.2:latest",
    api_key="your-api-key",      # if needed
    temperature=0.7,             # model temperature
    max_tokens=4000,             # max response length
    base_url="http://localhost:11434/v1",  # model API endpoint
)

🧩 Available Agents

ChatLite supports different agent types for specialized tasks:

• WebSearchAgent: Internet-enabled chat with web search capabilities
• RawWebSearchAgent: Direct web search results without summarization
• EmailAssistantFeature: Email composition and analysis
