Amazon EC2 Inf2 instances, optimized for generative AI, now available in US West (Oregon) region

Starting today, the Amazon Elastic Compute Cloud (Amazon EC2) Inf2 instances are generally available in the US West (Oregon) region. These instances deliver high performance at the lowest cost in Amazon EC2 for generative AI models.

You can use Inf2 instances to run popular applications such as text summarization, code generation, video and image generation, speech recognition, personalization, and more. Inf2 instances are the first inference-optimized instances in Amazon EC2 to introduce scale-out distributed inference supported by NeuronLink, a high-speed, nonblocking interconnect. Inf2 instances offer up to 2.3 petaflops and up to 384 GB of total accelerator memory with 9.8 TB/s bandwidth. Inf2 instances deliver up to 40% better price performance than other comparable Amazon EC2 instances.

The AWS Neuron SDK integrates natively with popular machine learning frameworks, so you can continue using your existing frameworks to deploy on Inf2. Developers can get started with Inf2 instances using AWS Deep Learning AMIs, AWS Deep Learning Containers, or managed services such as Amazon Elastic Container Service (Amazon ECS), Amazon Elastic Kubernetes Service (Amazon EKS), and Amazon SageMaker.

Inf2 instances are available in four sizes: inf2.xlarge, inf2.8xlarge, inf2.24xlarge, inf2.48xlarge in the following AWS Regions as On-Demand Instances, Reserved Instances, and Spot Instances, or as part of a Savings Plan: US East (N. Virginia), US East (Ohio), and US West (Oregon).
