// about GPT-5
GPT-5 is OpenAI's flagship model and the engine behind the current version of ChatGPT. It handles text, images, audio, and code in one model, and it decides how much to think about a problem based on how hard the problem is, so simple questions come back quickly while harder ones get more reasoning. It is a common default for coding, long analysis, and agent workflows, and it is available in ChatGPT and through the OpenAI API that a large share of AI products are built on.
