GPT 5.5 just dropped and this is not just another model bump. It's a genuinely different kind of upgrade.
In this Short I'm breaking down the two features that stood out to me most: coding execution and search/document work. On the coding side, GPT 5.5 handles multi-file refactors, debugging, and full feature implementations with way less back and forth. It breaks hard problems down and gets a usable result on the first pass. On the research side, you can point it at a PDF or policy doc, ask it something ambiguous, and it actually grounds its answer in the source material instead of guessing.
There's more in this release too. Computer use for clicking through apps and dashboards, better efficiency on complex multi-step tasks, less wasted work across the board. Whether you're using ChatGPT, Codex, or the API, this one's worth trying.
