Hi everyone,

https://github.com/marketplace/models/azure-openai/gpt-4o/playground
i am a student and cant afford to pay for these models , my qustion is , if i use those models in the playground or in my code .will i be charged for use as there is a limit per day (like if i will exceed it , or how will i know how much resources i have used ).
