Researchers have developed a novel method called Verifier-Based Reinforcement Fine-Tuning (RLVR) to adapt open-weight reasoning models for complex control tasks, such as managing thermal energy storage in buildings. This approach converts exact dynamic programming action values into dense rewards, enabling fine-tuning with a small number of prompts. The study demonstrated that RLVR significantly reduced emissions in a simulated office building, bringing performance close to an optimal dynamic programming solution. Notably, GPT-5 showed strong performance without task-specific training, while GPT-4o struggled, highlighting the importance of inference-time reasoning capabilities. AI
