OpenAI Cuts GPT-5.6 Luna Prices by 80 Percent
Major API pricing adjustments follow efficiency gains amid intensifying AI competition.
Multiple independent sources confirm OpenAI announced sharp price reductions on its GPT-5.6 model family through the API. Luna receives the largest cut while Terra sees a smaller adjustment and Sol pricing stays unchanged. Analysts link the move to inference stack improvements and a new speculative decoding engine. Observers note the changes align costs with real task performance, benefit frequent users, and reflect broader competitive dynamics pressuring frontier labs to optimize delivery.
We are committed to pushing the model frontier across cost efficiency, capability, and speed. Starting today, we are reducing prices for GPT-5.6 Luna by 80% and GPT-5.6 Terra by 20% , and offering a faster option for GPT-5.6 Sol in the API. Luna and Terra’s lower prices are…
