Researchers have developed ShellElastic, a novel approach to training foundation models that efficiently supports diverse inference budgets. This method trains nested sub-networks within a single supernet, overcoming challenges like variable workloads, limited hyperparameter transfer, and ensuring all sub-networks are updated simultaneously. ShellElastic organizes hidden dimensions into a dense core and successive shells, allowing for a fixed computation graph and cost-effective training. The system also introduces \(\\mu\)E, an extension of maximal update parameterization, which guarantees all sub-networks are maximally updated and maintains optimal hyperparameters across different model sizes.
