Update to GPT-5 System Card: GPT-5.2

GPT‑5.2 is the latest model family in the GPT‑5 series, and explained in our blog⁠. The comprehensive safety mitigation approach for these models is largely the same as that described in the GPT‑5 System Card⁠ and GPT‑5.1 System Card⁠.

In this card we also refer to GPT‑5.2 Instant as gpt-5.2-instant and GPT‑5.2 Thinking as gpt-5.2-thinking.
