In September 2024, OpenAI launched an updated version of ChatGPT that significantly enhances its ability to reason through complex tasks in areas such as math, science, and programming.

This new reasoning technology has reportedly outperformed other leading A.I. systems in various tests designed to measure advancements in A.I.

Reasoning in A.I. involves additional processing time where the system breaks down a problem or uses trial and error to arrive at a solution.

Unlike earlier versions that provided immediate responses, this updated ChatGPT takes time to 'think' before delivering answers, showcasing its advanced reasoning capabilities.

Dan Klein, a computer science professor at UC Berkeley, elaborates that this reasoning process involves the system performing extra work after a question is posed, which is a departure from the instant responses of previous models.

In addition to OpenAI, other companies such as Google, Anthropic, and China's DeepSeek have also developed similar reasoning capabilities in their A.I. systems.
