AWS integrates NVIDIA NVRx into PyTorch FSDP on Amazon EKS for fault-tolerant training
AWS published a guide for integrating NVIDIA Resiliency Extension (NVRx) into PyTorch FSDP training on Amazon EKS. It covers async checkpointing, in-process restart, and ft_launcher in-job restart. H100 benchmarks across 2 to 8 nodes showed over 99% training efficiency and recovery from GPU faults in seconds.

BlockRun and Incarna use Amazon Bedrock AgentCore payments for per-inference agent billing
Amazon Bedrock AgentCore payments lets AI agents pay for services on demand with infrastructure-enforced spending limits. Incarna's agents pay BlockRun for model inference one request at a time over x402, reducing the work of adding x402 payment support from months to days, according to an AWS Machine Learning Blog post.

PyTorch details session-aware agentic inference with NVIDIA Dynamo
PyTorch published a blog post describing session-aware agentic inference with NVIDIA Dynamo. It explains that agentic workloads differ from single-turn chat: an agent session can include a large initial prefill, repeated model calls, and parallel subagents, changing the traffic an inference server handles.
