LayerTrim: Structured Pruning Method Preserves LLM Reasoning Performance

LayerTrim is a training-free structured pruning technique that reduces LLM inference costs by trimming redundant decoder layers' MLP features while preserving attention mechanisms. This approach maintains reasoning performance on long-form tasks like AIME, addressing limitations of existing pruning...

AI-assisted summary based on the listed source.

Structured pruning reduces LLM inference costs by removing model components to produce smaller dense models. However, existing methods can cause reasoning performance to collapse on long-form reasoning tasks such as AIME. We propose \textit{LayerTrim}, a training-free structured pruning method that identifies...

Reducing inference costs without sacrificing reasoning ability is critical for deploying large language models efficiently. LayerTrim offers a practical solution by selectively pruning model components to keep performance intact on complex reasoning tasks.
