The Reinforcement Gap: Why Some AI Skills Improve Faster Than Others

Reinforcement learning gaps affect AI skill progress

Some AI skills advance quickly while others improve slowly. This difference is due to the ability to measure and test performance effectively.

  • AI coding tools are improving rapidly
  • Reinforcement learning accelerates coding skills
  • Skills like writing progress slowly
  • Testing is easier for certain tasks
  • Sora 2 shows advances in video AI
  • Reinforcement gap impacts startups
  • Future of many jobs may be uncertain

AI coding tools are advancing quickly, especially with new models like GPT-5, Gemini 2.5, and Sonnet 4.5. However, other AI skills, such as writing emails, are not improving as much, reflecting a disparity in progress known as the reinforcement gap.

Rapid improvements in AI coding

Coding applications benefit from many measurable tests. These tests allow models to learn and produce working code efficiently through reinforcement learning (RL). This approach has driven AI advancements significantly over the past six months.

As reliance on RL increases, notable differences emerge. Skills like bug-fixing improve rapidly due to clear grading metrics, whereas less measurable skills like writing see only slight progress.

Challenges in measuring some skills

Unlike coding, validating tasks like writing or responding as a chatbot is subjective and difficult to test at scale. Although not all tasks fit neatly into easily or hard-to-test categories, some areas, like financial reporting, could still benefit from tailored testing solutions.

Companies that develop effective testing kits could turn challenging processes into successful products, highlighting the importance of testability in AI advancements.

Emerging technologies and future impacts

Some processes may be more testable than expected. For instance, OpenAI’s Sora 2 model shows significant advancements in AI-generated video, achieving improvements in realism and consistency.

The ongoing role of reinforcement learning in AI development shapes which processes can be automated successfully. This growth creates potential shifts in the job market, especially in fields like healthcare, as tasks become more trainable through RL.
