PyTorch Conference North America 2026: Accelerating Open Intelligence Together

PyTorch Conference North America 2026 brought 3,500+ attendees to San Jose on October 20–21 for two days focused on accelerating open intelligence and exploring the impact of PyTorch Foundation projects like PyTorch, vLLM, DeepSpeed, Ray, H

Fast by Default: Compile-Time Heuristics for Helion Kernels

TL;DR Helion now uses compile-time heuristics that analyze a kernel’s IR and dataflow to pick fast settings without slow autotuning. It classifies the kernel as matmul, reduction, or pointwise and chooses block sizes, warps, and stage

Integrating SGLang into Spyre in Under a Week with AI

TL;DR With help from AI coding agents, our two-person team integrated SGLang with IBM Spyre in less than a week, building a plugin of roughly 1,500 lines. Existing Spyre support in PyTorch and SGLang’s clear extension points made it s

Training a 1T-Parameter MoE on EU public infrastructure with PyTorch and TorchTitan

TL;DR Scaling pretraining for a ~1-trillion-parameter Mixture-of-Experts (MoE) model on shared, public infrastructure was previously considered unfeasible due to unique architectural and interconnect bottlenecks. However, by leveraging the
