LFM2.5-1.2B-JP-math-aggressive

MATH-optimized | Aggressive pruning | 35% weights pruned

This model is a aggressively pruned version of LiquidAI/LFM2.5-1.2B-JP.

Note: Minimal quality drop detected. The Wanda pruning algorithm effectively identifies and removes less important weights while preserving model capability.
