AWS Inferentia & Trainium
AWS Inferentia and Trainium are Amazon Web Services' custom-built machine learning accelerator chips designed to deliver high performance and cost efficiency for AI workloads.
AWS Inferentia
AWS Inferentia chips are purpose-built for high-performance machine learning inference. They are designed to deliver the lowest cost per inference in the cloud, making them ideal for deploying trained models at scale. Inferentia powers Amazon EC2 Inf1 and Inf2 instances, supporting popular frameworks like PyTorch and TensorFlow through the AWS Neuron SDK.
AWS Trainium
AWS Trainium is the second-generation custom chip designed specifically for deep learning training. It offers the best price-performance for training machine learning models in the cloud. Trainium powers Amazon EC2 Trn1 instances, enabling customers to train large language models (LLMs), computer vision models, and other complex ML workloads efficiently.
AWS Neuron SDK
Both chips are supported by the AWS Neuron SDK, which integrates with popular ML frameworks and allows developers to easily compile and deploy models on Inferentia and Trainium-based instances with minimal code changes.
