IDEA Prune: An Integrated Enlarge-and-Prune Pipeline in Generative Language Model Pretraining
Apple's research challenges model-training dogma: enlarge-then-prune beats training small from scratch.

Why it matters
A structured pruning approach from Apple ML Research suggests that pretraining oversized models and pruning them down is more efficient than training target-size models directly—potentially reshaping how practitioners optimize for inference budgets.

Publisher excerpt: Recent advancements in large language models have intensified the need for efficient and deployable models within limited inference budgets. Structured pruning pipelines have shown promise in token efficiency compared to training target-size models from scratch. In this paper, we advocate…
