Muon has attracted a lot of attention for fast convergence, but getting those optimizers to work in a real training stack is a different challenge.

At PyTorch Conference North America, @JenniferWe17599 will walk through Muon, Dion, and Dion3 and look at what happens when you add the messy details: sharding, communication, schedulers, and everything else that can go wrong.

If you are interested in optimizers and training dynamics, see you at PyTorchCon NA for Jen's talk on Beyond AdamW: A Practical PyTorch Walkthrough of Muon, Dion, and Orthogonalized Optimizer Variants.

For supported biomolecular structure-prediction models, NVIDIA BioNeMo Inference Runtime keeps the familiar PyTorch workflow and lets developers construct supported models as torch.nn.Module objects or reuse selected modules in custom code.

In a new NVIDIA Developer Blog post, the team details how BioIR uses optimized kernels and, where applicable, CUDA Graphs for model execution, with Ray replicas for processing large batches of independent inputs across GPUs in a single node.

This post covers BioIR acceleration for Boltz-2, OpenFold2, and OpenFold3.

At PyTorch Conference North America 2026, Dhritiman Das, Staff Software Engineer - Machine Learning Infrastructure (@LinkedIn), will present a torch-native retrieval engine that uses PyTorch as the primary runtime for retrieval, filtering, and ranking.

The system combines a GPU-resident torch tensor index, tensor-based retrieval operations, custom CUDA kernels for attribute filtering, and TorchScript model execution within a unified serving architecture orchestrated through a Rust and tch-rs backend. Dhritiman will also share how the approach scales to critical use cases like feed and search at LinkedIn.

New from @Meta Engineering: FlashAttention-4 extended with MXFP8 support for @nvidia Blackwell—from forward and backward kernels to fused quantization and jagged cross-attention.

The team developed an end-to-end jagged module with fused quantization, FP8 activation and compute which is being used internally at Meta for GEM training. On the latest gen hardware, LP FA4 kernel reaches 2.85 PFLOP/s forward and 2 PFLOP/s backward, with up to a 1.30× end-to-end module speedup.
