OpenAI's recently unveiled o3 model is purportedly its most powerful AI yet, but with one big drawback: it costs ungodly sums of money to run, TechCrunch reports.

Announced just over a week ago, o3 "reasons" through problems using a technique known as test-time compute — as in, it takes more time to "think" and explore multiple possibilities before spitting out an answer. As such, OpenAI engineers hope that the AI model will produce better responses to complex prompts instead of jumping to a faulty conclusion.
