Using the Paid Version of ChatGPT Affordably via API#

Background/Problem#

To use the paid version of Chat GPT offered by OpenAI, a monthly subscription fee of $20 is required.
(As of June 2024, this amounts to approximately 30,000 KRW when applying the exchange rate for South Korea.)
Paying $20 every month can feel expensive for those with low usage.

Improvement#

To address this issue, I will explain a simple coding method that allows for pay-as-you-go usage.
OpenAI provides an API for the Chat Bot, which operates on a pay-as-you-go basis.
Therefore, if your monthly usage is low, using the API can be more cost-effective than subscribing.
