AI Coding Tools Outpace Other Skills Thanks to Reinforcement Learning

AI systems like GPT-5, Gemini 2.5 and Sonnet 4.5 have dramatically improved at coding tasks due to reinforcement learning, which lets models test billions of outputs against clear pass/fail metrics.
But AI progress in subjective areas like email writing and chatbots has slowed. Analysts call this the “reinforcement gap,” noting that tasks easy to test automatically—like bug-fixing—advance far faster than tasks that are harder to score.
