Amazon EC2 Trn1n instances, optimized for network-intensive generative AI models, are now generally available

Today, AWS announces the general availability of Amazon Elastic Compute Cloud (Amazon EC2) Trn1n instances, which are powered by AWS Trainium accelerators. Building on the capabilities of Trainium-powered Trn1 instances, Trn1n instances double the network bandwidth to 1600 Gbps of second-generation Elastic Fabric Adapter (EFAv2). With this increased bandwidth, Trn1n instances deliver up to 20% faster time-to-train for training network-intensive generative AI models such as large language models (LLMs) and mixture of experts (MoE). Similar to Trn1 instances, Trn1n instances offer up to 50% savings on training costs over other comparable Amazon EC2 instances.
