Part 3/11:
GPT-5 Mini: A faster, cost-effective version that outperforms previous models like GPT-3 on many benchmarks, serving as a high-volume workhorse for daily tasks.
GPT-5 Nano: An ultra-efficient model, approximately 25 times more affordable than the flagship, optimized for applications where speed and cost are critical.
A defining characteristic of GPT-5 is its adaptive reasoning—it adjusts its level of effort depending on the complexity of the task. Simple questions get quick responses, while complex problems trigger deep analytical thinking without sacrificing speed. This versatility was vividly demonstrated when GPT-5 autonomously created a physics visualization in just two minutes—a task that took human developers three weeks in 2022.
