Ask HN: Has degradation in the quality of ChatGPT and Claude been proven?

Has there been any consensus on this phenomenon I've seen where there are reports of decrease in model performance? This decrease in quality seems to take many forms: laziness, lower expressiveness, mistakes, laziness etc.

One the other hand there are people who claim there hasn't been any degradation at all[0]?

If there is indeed no degradation how could the perceived degradation be explained?
