About GPT-5

GPT-5 was OpenAI's flagship model generation, offered through the OpenAI API for developers and integrated into ChatGPT for consumer use, succeeding the earlier GPT-4 generation.

Like earlier GPT generations, it served as the basis for a family of variants at different price and capability points, and was used across OpenAI's own products as well as many third-party applications built on the API.

OpenAI has since released several newer model generations, including a GPT-5.6 family and a GPT-6 family, and current OpenAI pricing documentation no longer lists GPT-5 among its primary active offerings.
