SmarxPython Update: Python 3.14 Support and New PyTorch AI Model Protection Sample
2 September 2026
MARX® introduces a major update for SmarxPython, bringing Python 3.14 support for Windows 11 and a new PyTorch sample for protecting AI models with the CRYPTO-BOX®.
Python continues to play an important role in modern software development, including data science, machine learning and artificial intelligence. With the new SmarxPython update, MARX® expands support for developers using the latest Python environments and introduces a new sample for protecting valuable AI models.
Support for Python 3.14 under Windows 11
The updated SmarxPython package now provides support for Python 3.14 on Windows 11, enabling developers to integrate the CRYPTO-BOX® into applications developed with the latest Python version.
SmarxPython provides libraries and sample code for implementing software protection and license management with the CRYPTO-BOX in Python applications. It allows developers to implement strong hardware-based security directly into their applications.
New PyTorch Sample: Protect Your AI Models
A key highlight of this update is the new PyTorch protection sample.
Artificial intelligence models often represent a significant investment. Training data, development time and computing resources are used to create valuable machine learning models. Once a model is distributed, protecting it against unauthorized copying and use becomes an increasingly important challenge.
The new PyTorch sample demonstrates a practical approach to combine AI innovation with hardware-based software protection. The PyTorch AI model is encrypted, and the required cryptographic key is protected by the CRYPTO-BOX® hardware security device. The protected AI model can only execute if the matching CRYPTO-BOX is available.
This provides an additional layer of protection for valuable AI assets and helps software vendors protect their machine learning and AI models against unauthorized copying and use.
The updated SmarxPython package, including the latest libraries and sample code, will be available in our download section
