OpenAI Releases GPT-5.2

OpenAI:

In ChatGPT, GPT‑5.2 Instant, Thinking, and Pro will begin rolling out today, starting with paid plans. In the API, they are available now to all developers.

Overall, GPT‑5.2 brings significant improvements in general intelligence, long-context understanding, agentic tool-calling, and vision — making it better at executing complex, real-world tasks end-to-end than any previous model.

5.1 was released just one month ago, but 5.2 delivers a slew of measurable improvements across the board. Where 5.1 was seemingly more about the feel of responses, the personality, 5.2 was clearly focused on tangible and benchmarkable gains.
