It builds on the GPT-5 and GPT-5.1 generations with further improvements across reasoning depth, coding capability, instruction following, and multimodal understanding.
As the standard tier in the GPT-5.2 family, it provides the balance of capability and accessibility that most demanding applications require. The context window of 400K tokens supports extensive inputs, and the model handles text, image, and mixed-modality inputs with GPT-5.2 generation quality.
If you already use GPT-5 or GPT-5.1, GPT 5.2 offers an upgrade path with measurable improvements across key benchmarks.
