Model names are too broad

[seungduk-yanolja]

There could be various GPT-4 models like this:
https://platform.openai.com/docs/models/gpt-4-turbo-and-gpt-4

Their performance can be notably different, we better use specific model names like gpt-4-turbo-2024-04-09 which would not change over time.
And we better avoid using model names like gpt-4, gpt-4-turbo, or gpt-4-turbo-preview.
