The models provided by OpenAI such as ChatGPT Completion or Chat models have dates when they become deprecated, after the mentioned dates they won't work and you will be faced with.
"Failed to get response from the server, status code: 404".For example, anyone in their flutterflow apps using these models below,
text-babbage-001
text-curie-001
text-davinci-001
text-davinci-002
text-davinci-003
won't be able to use them anymore, hence, there is a recommended replacement for these models which is :gpt-3.5-turbo-instruct
These models were deprecated the first week of January.
Similarly, GPT 3.5 models will also be deprecated after some time. So you should take note.
You can find more details about which models to use and what the cost of each model here

Feel free to update them by simply changing the names of models in your API call.
So your end users don't face any issues with your application.
Hope this helps. Peace ✌️
