GPT-5.2 Pro in plain words

GPT-5.2 Pro is a text model from OpenAI. It takes images, text, and files as input and returns text. Its context window is 400,000 tokens. It costs 26.064706 credits per 1M input tokens and 208.517648 credits per 1M output tokens.

It is good at reasoning through multi-step problems, reading attached files, and calling tools. It reads images as well as text. A context window of 400,000 tokens holds about 1,600,000 characters of English text, at 4 characters a token.

For example, a question of 2,000 tokens (about 8,000 characters) with an answer of 1,000 tokens (about 4,000 characters) costs 0.260648 credits. The exact charge follows the usage the model reports for your request.
