About GPT-5.4
GPT-5.4 is a text generation model. You type a message and it writes text back. It is made for reasoning and coding.
You provide one thing: your message. Type it into the Prompt box (the hint reads Enter Your Message). The reply comes back as written text.
GPT-5.4 Mini and GPT-5.4 Nano use the same message box and also return text. They differ from GPT-5.4 in price. GPT-5.4 costs about 2550 credits per run.
