OpenAI Slashes GPT-5.6 Prices as Fields Medalist [Model Behavior]
Welcome to Model Behavior. In this program, we provide a forensic examination of how artificial intelligence systems are being constructed, deployed, and utilized within professional environments. We focus on the intersection of technical innovation and the regulatory and economic frameworks that define the current AI landscape. I am glad you could join us for this briefing. <br/><i>acting_description:</i> Professional, steady, welcoming <i>speed:</i> 0.98 <i>trailing_silence:</i> 0.3 Today is July 31st, 2026, and we are monitoring a major inflection point in the economics of frontier models. Yesterday's comprehensive pricing announcement from OpenAI has effectively shifted the cost structure for the entire industry. It appears we are entering a new phase where the price of intelligence is falling faster than most analysts predicted. <br/><i>acting_description:</i> Grounded, focused, informative <i>speed:</i> 1.0 <i>trailing_silence:</i> 0.4 OpenAI has effectively ignited a new phase of the AI price wars. They’ve announced substantial cuts to their GPT-five.six series, with the smallest model in that family, Luna, seeing its price slashed by eighty percent. This moves Luna into a much more competitive tier, pricing it at twenty cents per million input tokens and one dollar and twenty cents per million output tokens, Thatcher. <br/><i>acting_description:</i> Confident, authoritative, measured <i>speed:</i> 0.97 <i>trailing_silence:</i> 0.2 It is a massive move, Nina. For context, that puts Luna’s combined price at a dollar forty per million tokens. Looking at the broader market, that undercuts Google’s Gemini three.five Flash-Lite, which sits at a combined two dollars and eighty cents. It seems OpenAI is no longer content just competing on intelligence
