Hi Anuj Kumar,
Thank you for reaching out to Microsoft Q & A forum.
We apologize for any inconvenience caused. The services utilized in OpenAI operate on a pay-as-you-go basis. Microsoft provides a free trial account as well.
I recommend creating a personal Azure account.
The Azure free account offers complimentary access to various Azure products for a duration of 12 months. Additionally, you will receive a $200 credit for the initial 30 days after sign-up, along with access to over 40 services that are available always free of charge.
You can sign up for Azure Free Trial subscription here: Create Your Azure Free Account Today | Microsoft Azure
There is also Azure Free for Students:
