TensorStack

A modular .NET SDK for building AI-powered applications.

TensorStack provides reusable components for local AI inference, text generation, image generation, media processing, hardware acceleration, and application development through a unified developer experience.

Built for performance and flexibility, TensorStack powers all applications developed by TensorStack-AI, including Amuse, the official reference application and UI demonstration of the platform.
