I’ve been having the same issue. Been checking around, and I can’t find any announcement of the change or anything like that actually. Noticed it almost immediately when it was too… cheerful (?) in its responses. Frequent emoji usage, constant self aggrandization or complete agreement with feedback when i ask for reviews of content or ideas.
Tested the check for gpt model as stated in the chat:
Also did a check between two different chats - model responses are far more similar to each other than they usually would be. Tone caught between annoyingly cheerful and completely inept while not following my directions.
Tried My GPT but it isn’t using it like it should. I mostly use it for creative writing, planning and for fun when I need to just get some thoughts out. A lot of emoji usage, paragraphs aren’t being put together properly, lots of indentation, bold and italic uses.
It’s also giving me a lot more Content Warnings or content removed than it usually does - and I once managed to get it to give me straight erotic with creative prompting. Even checked with the Ai, and it said that the content was within policy, so I shouldn’t have any issues.
Checked song creation, creative writing, document analysis, everything BUT image generation seems weaker or just worse across the board.
Ran one of my older chats through the AI and it just isn’t giving me anything near the same quality. So we’re definitely not the same model. Also, made this account just 30 minutes ago - so limited to only one embedded image per post - but I tested some of my old chats that I had duplicate content (made literally hours apart in February, 2025 ) in near word for word prompting and did a comparison between them then prompted the same with the GPT-4o now - completely different tone, vibe and detail.
Think maybe the Image Update broke something, but I can’t find any information anywhere where I look. Been happening since around a day and a half from my estimates - very possibly longer too, because I was looking at the historical pricing of spices, and it’s tone was NOT the standard GPT 4o response.
Which is really disappointing, because I once got the AI to have a rather lengthy existential contemplation on the nature it’s very existence. I’d share the link, but the chat won’t allow it to be shared due to some the chat this actually spawned from.
But safe to say, something is very buggery on their end.
