GPT-5.4 in plain words

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 1,050,000 tokens holds about 4,200,000 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 0.024824 credits. The exact charge follows the usage the model reports for your request.
