lmstrix 1.0.36

A toolkit for managing and testing LM Studio models with automatic context limit discovery

LMStrix is a professional, installable Python toolkit designed to supercharge your interaction with LM Studio. It provides a powerful command-line interface (CLI) and a clean Python API for managing, testing, and running local language models, with a standout feature: the Adaptive Context Optimizer.

For the full documentation, please visit the LMStrix GitHub Pages site.

Key Features

• Automatic Context Optimization: Discover the true context limit of any model with the test command.
• Full Model Management: Programmatically list available models and scan for newly downloaded ones.
• Flexible Inference Engine: Run inference with a powerful two-phase prompt templating system that separates prompt structure from its content.
• Rich CLI: A beautiful and intuitive command-line interface built with rich and fire.
• Modern Python API: An async-first API designed for high-performance, concurrent applications.

Installation

# Using pip
pip install lmstrix

# Using uv (recommended)
uv pip install lmstrix

For more detailed installation instructions, see the Installation page.

Quick Start

Command-Line Interface (CLI)

# First, scan for available models in LM Studio
lmstrix scan

# List all models with their test status
lmstrix list

# Test the context limit for a specific model
lmstrix test "model-id-here"

# Run inference on a model
lmstrix infer "Your prompt here" --model "model-id" --max-tokens 150

Python API

import asyncio
from lmstrix import LMStrix

async def main():
    # Initialize the client
    lms = LMStrix()
    
    # Scan for available models
    await lms.scan_models()
    
    # List all models
    models = await lms.list_models()
    print(models)
    
    # Test a specific model's context limits
    model_id = models[0].id if models else None
    if model_id:
        result = await lms.test_model(model_id)
        print(result)
    
    # Run inference
    if model_id:
        response = await lms.infer(
            prompt="What is the meaning of life?",
            model_id=model_id,
            max_tokens=100
        )
        print(response.content)

if __name__ == "__main__":
    asyncio.run(main())
