AWS Neuron introduces speculative decoding

Today, AWS announces the release of Neuron 2.18, introducing stable support (out of beta) for PyTorch 2.1 and adding support for speculative decoding with Llama-2-70B sample in Transformers NeuronX library.

AWS Neuron is the SDK for Amazon EC2 Inferentia and Trainium based instances purpose-built for generative AI. Neuron integrates with popular ML frameworks like PyTorch and TensorFlow. It includes a compiler, runtime, tools, and libraries to support high performance training and inference of generative AI models on Trn1 instances and Inf2 instances.

This release also adds new features and performance improvements for both LLM training and inference, and updates Neuron DLAMIs and Neuron DLCs. For training, NeuronX Distributed adds asynchronous checkpointing support, auto partitioning pipeline parallelism, and introduces pipeline parallelism in PyTorch Lightning Trainer (Beta). For inference, Transformers NeuronX improves weight loading performance by adding support for SafeTensor checkpoint format and adds new samples for Mixtral-8x7B-v0.1 and mistralai/Mistral-7B-Instruct-v0.2. NeuronX Distributed and PyTorch NeuronX add support for auto-bucketing.

You can use AWS Neuron SDK to train and deploy models on Trn1 and Inf2 instances, available in AWS Regions as On-Demand Instances, Reserved Instances, Spot Instances, or part of Savings Plan.
