GPT‑5.5 also scores higher on math and multimodal reasoning benchmarks, and introduces a context‑management feature that lets the model reference past chats, files and Gmail. The changes roll out to Plus and Pro users on the web now, with broader availability slated for mobile and other plans in the coming weeks. Read more →
