Build and Scale AI With PyTorch on Arm Cloud

This is your technical guide to setting up, optimizing, and deploying high-performance AI models on Arm cloud infrastructure using PyTorch and open-source tools.


Benefits of Running PyTorch on Arm Cloud


Running PyTorch on Arm-based CPUs like AWS Graviton, Microsoft Cobalt, Nvidia Grace, Google Axion and others provides developers with a cost-effective and scalable way to deploy AI inference workloads using high-performance CPUs. By leveraging Arm architectural features like NEON and SVE, PyTorch can execute matrix-heavy models such as LLMs and Transformers efficiently. This enables greater portability, lower memory usage, and easier integration into production pipelines. Using Llama.CPP? Go to the Llama.CPP Developer Launchpad.

Set Up

PyTorch logo

To start developing with PyTorch on Arm-based systems, you’ll first need to set up your development environment. This includes installing PyTorch, validating your setup, and running your first model using beginner tutorials.

Before starting, make sure you have:

  • A 64-bit Arm CPU (Armv8-A or newer)
  • Python 3.8+
  • pip, virtualenv, and build essentials
