Behind 2.5x Growth: GPT-5.6's Agentic Effect Is More Than Just 'Usability'

Using chemical reactions as an analogy, the launch of the GPT-5.6 series models is like adding a new active site to an already saturated catalyst system. The 2.5x increase in usage volume, if you only look at the numbers, can easily be interpreted as "users love it more." But as someone who spends all day running benchmarks and staring blankly at token consumption curves, I see a deeper engineering logic being validated.
