Hello Muhammad Faran Javaid,
Welcome to the Microsoft Q&A and thank you for posting your questions here.
I understand that you would like to be certain on how your flows deployed on PromptFlow are charged.
Azure AI Studio provides two pricing models both Pay-As-You-Go (PAYG) and hourly charge and the cost depends on the specific services and resources you use. For your Promptflow, the charges are based on the deployment level and the AI services you consume. This means that it depends on the scale and complexity of your deployment and also, the specific AI services you use, such as natural language processing, computer vision, or custom models.
The best way to get an idea is to use Azure Pricing Calculator https://azure.microsoft.com/en-us/pricing/calculator to estimate your costs based on your expected usage AND/OR use Azure Cost Management https://azure.microsoft.com/en-us/services/cost-management
I hope this is helpful! Do not hesitate to let me know if you have any other questions.
