What is the cut-off knowledge base in GPT plus

I am using GPT 4, but all the time it says the knowledge cut-off is September 2021. Is this a known issue or I am making any mistake?

Welcome to the forum!

That is correct, the dataset GPT-4 was trained on has a cut-off of September 2021

You have 3 options to bring the knowledge up to date for your own specific use case:

  1. Add the required info straight into your prompt as a doc (ok for very specific use cases with a small scope)
  2. Add the info to a vector db and query the db at run time to extract up-to-date info required by the prompt.
  3. Utilize a browser plugin/function to search the net at run time & find the info needed.
