Announcing AWS Neuron SDK 2.27.0

Posted on: Dec 22, 2025

Today, AWS announces Neuron SDK 2.27.0, introducing support for Trainium3 UltraServer with expanded open source components. Neuron also introduces the Neuron Explorer tools suite, Enhanced NKI with open source NKI Compiler built on MLIR (private beta), the NKI Library of optimized kernels, native PyTorch support through TorchNeuron (private beta), and Neuron DRA for Kubernetes-native resource management (private beta).

These updates enable standard frameworks to run unchanged on Trainium, removing barriers for researchers to experiment and innovate. For developers requiring deeper control, the enhanced Neuron Kernel Interface (NKI) Beta 2 provides direct access to hardware-level optimizations, enabling customers to scale AI workloads with improved performance. If you're interested in early access to new NKI features and improvements, you can join the Neuron private beta program.

The new SDK version is available in all AWS Regions supporting Inferentia and Trainium instances, offering enhanced performance and monitoring capabilities for machine learning workloads.
