text: My friend guy wrote a post titled as "The LLM world full of WAITLIST" in an online forum as following:
  
  I use OpenAI's ChatGPT API in my app, the model available in the API is gpt-3.5-turbo. gpt-3.5-turbo is very good for practice as the API charges by the number of tokens, but gpt-3.5-turbo charges less per token. However, gpt-3.5-turbo has a limited number of tokens, which can lead to unsatisfactory results. Therefore, I would like to use gpt-4, but I have to register on waitlist to use it in the API.
  
  On the other hand, there is Microsoft's Azure OpenAI Service. This is a service that allows you to use the OpenAI API in Azure; Microsoft has invested in OpenAI and therefore has priority access to it. For example, GitHub's Copilot is another Microsoft-related example of OpenAI being available. I have a $50/mon Azure coupon because I am on Visual Studio Subscription.
  
  However, Azure only supports up to gpt-3.5-turbo, so I wanted to use the Azure OpenAI Service immediately, which also requires registration on waitlist. This time I registered for two waitlists.
  
  In the future, I would like to practise inexpensively using Azure gpt-3.5-turbo with Azure coupons; once I am sufficiently satisfied about gpt-3.5-turbo, I would like to try gpt-4.
