Researchers have developed a spectral framework to address challenges in scaling generative foundation models, particularly in stable feature learning and hyperparameter transfer across varying widths and depths. This framework unifies existing maximal update parameterization ($\mu$P) formulations and identifies a CompleteP-style parameterization as more suitable for architectures like Transformers. Experiments on GPT-2 style models demonstrate that this CompleteP-style parameterization ensures stable learning and robust hyperparameter transfer, unlike standard or Depth-$\mu$P-style parameterizations.
