OpenAI’s most famous and revolutionary product, ChatGPT Plus, comes with a price tag of $20 per month, granting you access to both GPT-4 and GPT-3.5, with this features:
-Available even when demand is high
-Faster response speed
-Priority access to new features
This subscription provides you with more than enough chats per month; however, there are certain restrictions for GPT-4 (GPT-4 currently has a cap of 25 messages every 3 hours).
Nonetheless, if you have an application that allows you to use your own API, you will pay as you go and not only will it be more cost-effective, but you will also be able to use GPT-4 with fewer limitations.
