Analysis of five AI performance benchmarks spanning mathematics, hard sciences, and game-based puzzles shows a 47% per-quarter cost decline for a given level of performance. The study highlights a 725-fold price drop in 18 months: OpenAI's o3 model (January 2025) achieved a 75% score on GPQA Diamond for 30 cents per question; GPT-5.6 Luna achieved the same score for $0.0004 per question. The authors note that initial performance breakthroughs command premium pricing before competition drives costs down.
“No other general-purpose technology in history appears to have gotten so cheap so fast.”

The cost of achieving a given level of AI performance has fallen about 47% per quarter since 2023, or 13× per year. That price drop is four times faster than DNA sequencing, six times faster than compute, 18 times faster than lithium batteries, and (in the…
