Muon optimizer wins on data but lags on time for small models

Benchmark on small language and vision models shows Muon reduces validation loss by up to 22% at equal tokens, but its per-step overhead makes it slower in wall-clock time.

Muon optimizer achieves lower validation and test loss than AdamW when given the same number of training tokens on small language models and vision transformers.

70M-parameter vision transformer, using a single A100 GPU.
