GPT 5.6 discounts drove Terra/Luna token usage up to 13.8x, with ~32% user retention

GPT 5.6 折扣与杰文斯悖论：OpenRouter 数据揭示 Terra/Luna 降价如何引爆 token 用量

OpenRouter data shows that during OpenAI's July 27–Aug 14 discount on Terra and Luna, daily Terra tokens rose 5.6x and Luna 13.8x, while the undiscounted Sol model saw only a 1.1x bump. Most of the share gain came from competitors: the OpenAI family's token share grew from 7.1% to 12.4%, with roughly three-quarters taken from outside labs. After the discounts ended, about 32% of the 100K+ users who tried Terra/Luna kept using them, and 18% ran at or above their discount-period pace. Sol later reproduced the same spike when it got its own 50% discount on Aug 17.

Why it matters: First-party OpenRouter data showing market displacement after GPT 5.6 price cuts, with concrete multipliers and share shifts. Not an 85+ because it's platform analytics rather than a model capability update, but solid enough as a market signal for featured.
