GPT-5.2 is a large language model by OpenAI, released on December 11, 2025. Succeeding GPT-5.1, it is a family of three large language models within the GPT series. It comes in two modes: GPT-5.2 instant and GPT-5.2 thinking (with standard and extended thinking), with the latter being a reasoning model. A GPT-5.2 Pro model was released on the same day, which takes more reasoning time and compute than GPT-5.2 thinking. OpenAI also released a variant specialized for coding, GPT-5.2-Codex. The successor, GPT-5.3-Codex, was released on February 5, 2026, and by the following month, GPT-5.4, was rel

GPT-5.1 is a family of four large language models within OpenAI's GPT series. Two were released on November 12, 2025; two more were released one week later on November 19.
