Scaling Reinforcement Learning: Environments, Reward Hacking, Agents, Scaling Data The test time scaling paradigm is thriving. Reasoning models continue to rapidly improve, and are becoming more effective and affordable. Evaluations measuring real world software engineering tasks, like SWE-Bench, are seeing higher scores at cheaper costs. Below is a chart showing how models are both getting cheaper and better. Reinforcement learning (RL) is the reason […] https://semianalysis.com/2025/06/08/scaling-reinforcement-learning-environments-reward-hacking-agents-scaling-data/
