Hugging Face releases TorchNeuron public beta for AWS Trainium
Current overview (not historical)
Hugging Face has released TorchNeuron as a public beta, a new native backend for PyTorch that enables running Hugging Face models on AWS Trainium. Users can now run models by simply setting device_map=neuron, which significantly expands support from 46% to 89% of model architectures compared to the previous Optimum Neuron. The beta was released on October 20, 2026, and is installed via pip install torch-neuronx. Following the release, Hugging Face launched an interactive Space titled aws-neuron/torch-neuronx-model-support to check model compatibility and performance, though testing is limited to a maximum of four Trainium2 devices (16 cores), and PASS results do not guarantee throughput or long generation capabilities.

- Hugging Face Blog · Oct 23, 08:00Hugging Face Space allows users to check Transformer model compatibility on AWS Trainium
Following the introduction of TorchNeuron, Hugging Face launched an aws-neuron/torch-neuronx-model-support Space to check the compatibility and performance of popular Transformer models on AWS Trainium. The Space provides results including the number of Trainium cores used, compilation wall time, and peak device memory. Users can look up specific models via Trending or Downloads views, check model versions and Neuron compiler configurations, and access scripts to run models unmodified on Trainium2 (trn2) instances.

Hugging Face has released TorchNeuron, a new PyTorch plugin that adds a native backend for AWS Trainium. The backend supports eager execution, torch.compile, and distributed APIs such as FSDP and DTensor, allowing Transformers, Diffusers, Accelerate, PEFT, and TRL to run on Trainium with a simple device_map=neuron argument. From October 20, 2026, TorchNeuron will be available as a public beta via pip install torch-neuronx, and it already supports 89% of the top 100 text‑generation model architectures compared with 46% under Optimum Neuron.
