New EMNLP paper delivers 'downscaling laws': 10% lower loss costs 4-8x carbon, pruning 43% keeps 70% performance

Following their ICML 2025 position paper arguing the field needs downscaling laws, the team delivers one at EMNLP 2026 after pruning ten LLMs. Key findings: a 10% lower loss costs 4-8x the carbon emissions, while pruning 43% of a model keeps 70% of its performance with zero retraining. Their thesis: scaling laws tell you what a bigger model buys, but scaling down is the predictable, cheap path.
