NVIDIA researchers have introduced Star Elastic, a novel post-training method that embeds multiple reasoning models of varying parameter sizes within a single checkpoint. This approach allows for the extraction of smaller, nested submodels from a larger parent model without requiring additional fine-tuning. Star Elastic utilizes a trainable router and knowledge distillation to optimize the selection of model components, enabling efficient resource utilization and tailored model performance for different reasoning tasks.
