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, Jen Wei 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.
