Qwen2.5-Coder-7B Energy-SFT

Part of the Green Tea replication package for Beyond the Need for Speed: Energy-Aware Code Generation via Simulation-Guided Reinforcement Learning (Rajput and Sharma). Energy-contrastive supervised fine-tuning (LoRA r=64). On the 143-problem held-out benchmark it achieves 8.71% CARET (Correctness-Adjusted Reduction in Energy Total).
