openmux 0.1.11

A free multi-source GenAI orchestration library for automatic model selection and routing

OpenMux

Free Multi-Source GenAI Orchestration Library

OpenMux is a Python library that automatically selects, routes, and combines outputs from free GenAI models and API providers. It creates a unified interface for discovering, connecting, and using open-access models across the AI ecosystem — including OpenRouter, HuggingFace, Together AI, Mistral, Ollama, LM Studio, and other publicly available sources.

🚀 Quick Start

from openmux import Orchestrator, TaskType

# Initialize
orchestrator = Orchestrator()

# Process a query
response = orchestrator.process("What is Python?")
print(response)

# Process with specific task type
code_response = orchestrator.process(
    "Write a fibonacci function",
    task_type=TaskType.CODE
)

# Multi-model processing
combined = orchestrator.process_multi(
    query="Explain quantum computing",
    num_models=2,
    combination_method="summarize"
)

📦 Installation

From TestPyPI (Current)

# Using pip
pip install --index-url https://test.pypi.org/simple/ --extra-index-url https://pypi.org/simple/ openmux

# Using uv (recommended)
UV_HTTP_TIMEOUT=300 uv pip install --index-url https://test.pypi.org/simple/ --extra-index-url https://pypi.org/simple/ openmux

From PyPI (Coming Soon)

pip install openmux
# or using uv
uv pip install openmux

From Source

# Clone the repository
git clone https://github.com/mdnu838/OpenMux.git
cd OpenMux

# Create virtual environment
uv venv
source .venv/bin/activate  # On Windows: .venv\Scripts\activate

# Install in development mode
uv pip install -e ".[dev]"

Environment Setup

1. Copy the example environment file:

   cp .env.example .env
   

2. Add your API keys to .env:

   # OpenRouter (required for online models)
   OPENROUTER_API_KEY=your_key_here
   
   # HuggingFace (optional)
   HF_TOKEN=your_token_here
   
   # Ollama (for local models)
   OLLAMA_URL=http://localhost:11434
   

3. Never commit your .env file! It's already in .gitignore.
