Calculate Real ChatGPT API Cost for GPT-5, o3-mini, and Others (Data for 2025)
August 22, 2025 - 💡 Now here’s the kicker, if you’d switch to the cheaper gpt-5-mini model then the costs become basically $0. That gpt-5-mini is 1/5 the price of the main gpt-5.

To integrate ChatGPT into chatbot platforms, developers are supposed to set up API calls between their application and OpenAI’s servers.
