GPT 5.6 Discounts & Jevons Paradox
Article image or reusable cover for OpenRouter
OpenAI offered substantial discounts on its new Terra and Luna models between July 27 and August 14.
During this period, Terra token usage increased 5.6 times and Luna token usage 13.8 times, while the non-discounted Sol model increased only 1.1 times. Approximately one-third of users who tried the discounted models continued using them after the discount period ended. Most gains came from competitors rather than from other OpenAI models — OpenAI's total market share grew from 7.1 percent to 12.4 percent during the discount period.
Of the 100K+ customers with Terra/Luna usage during the program, about 32% retained some usage in the subsequent days and 18% ran at or above their program pace.
