I noticed my ChatGPT starting with 3.5 models selected for every new session last days, so I have to manually change to 4o. Service usage doesn’t seem to have increased last weeks according to specialized stats portals…
I rememeber I noticed a drop in the quality of the “model 4” weeks before the release of the 4o.
I also noticed a drop in the quality of MS Bing Chat (now Copilot) and their Dall-e generations before major updates around that same time.
Which raises a big question for me: do these models get worse with usage? Or are companies making things worse on purpose to build hype for adoption of the next update?
