In recent releases of ChatGPT, I have used it to summarize and analyze long texts (over 12000 characters), adding pieces of the text to the context (in pieces of up to 4000 characters). In versions prior to (ChatGPT Jan 30 Version), its operation was adequate for summarizing, obtaining key points of the entire conversation context.
In the current version (ChatGPT Jan 30 Version), ChatGPT loses the context of the conversation and is useless for what it could do before.
I add images with the added context and some correct responses, and the loss of context at the end.
I also add the text file I used for the test.
