GPT 5.6 DISCOUNTS & JEVONS PARADOX

Summary from the TLDR AI newsletter

OpenAI introduced large discounts on some of its models between July 27 and August 14. This resulted in Luna token usage jumping 13.8x and Terra token usage rising 5.6x while Sol, which remained at list price, only saw a bump of 1.1x. Most of the share gained by OpenAI's discounts came from other labs as opposed to cannibalization within the OpenAI family of models. Nearly a third of users who tried a discounted OpenAI model kept using it after the discounts expired.
