Karan Singhal of @OpenAI on the collapsing cost of intelligence, as seen on their health benchmark: "GPT-6 Luna is our current cheapest frontier model on the API... It performed better than 5.6 Sol, which was literally our best model a month ago. And it performs better despite being 34x cheaper." Most tiers of model intelligence became more than 100x cheaper within roughly a year One tier went from ~$32 to ~$0.02 per million tokens in two years
