the quality of the chat responses has significantly declined

Lately, the quality of the chat responses has significantly declined. Many questions that it previously answered well are now met with incomplete or incorrect responses. Unfortunately, it seems to struggle more often now.

For example, here is a question that it used to handle perfectly, but now it no longer provides a correct or useful answer. These changes have been noticeable over the past week and a half to two weeks, and I’ve observed a marked deterioration in its performance. It frequently fails to answer as effectively as before.
