In ChatGPT, full-stack inference improvements enable a more capable model at faster speed. This efficiency is a game-changer for GPT-5.5 Pro, now a much more practical option for demanding tasks, and a step change in the level of difficulty and quality of work ChatGPT can take on for people. Early testers described it as an iterative “research partner,” performing especially well when paired with contextual inputs from documents and plugins.
