arXiv:2606.19350v1 Announce Type: new Abstract: Large language models (LLMs) excel at multi-step reasoning but incur substantial inference cost. We introduce Causal Attribution Pruning (CAP), a training-free method that identifies critical attention heads by measuring their causal impact on reasoning tasks and uses these head-level scores to guide fine-grained weight pruning. For each attention head, CAP estimates the expected performance degradation when the head is masked during forward passes on a small calibration set of reasoning problems. These causal scores are then converted into weigh
The increasing computational demands of large language models are pushing researchers to find more efficient methods for deployment and inference.
Efficient pruning techniques are crucial for reducing the operational costs and environmental footprint of advanced AI models, making them more accessible and scalable.
The ability to significantly reduce LLM inference costs without sacrificing performance could accelerate wider adoption and enable new applications on resource-constrained devices.

Reduced computational resource requirements for deploying and running large language models.
Accelerated development and adoption of LLMs in diverse sectors due to lower operational barriers.
Increased competition among AI model providers as cost becomes a less significant barrier to entry, potentially fostering more specialized and efficient models.
