Why is my gpt4 latest database only updated to January 2022?

My friends’ phones are all updated to April 2023, but mine is not the latest. I don’t know if this is the reason why my gpt4 feels so stupid. Every answer to the question is very brief.

When using the OpenAI app, the AI is instructed to provide brief answers to make them easy to read.
