Context window full error appearing in completely NEW chats – AGAIN

Is anyone else experiencing this?

I’m getting the “context window full” message in brand-new conversations AGAIN, even when I’ve barely started talking.

This issue originally started happening to me on October 20, 2026. I submitted a report about it back then, and it stopped the following day, so I assumed whatever was causing it had been fixed.

However, it started happening again yesterday, November 5.

I’m honestly getting pretty frustrated because I don’t understand how a completely new conversation can already have a full context window. It’s not like I’m continuing an old conversation with hundreds of messages.

I’ve also seen other people reporting the same thing recently, so clearly I’m not the only one experiencing this.

Has anyone found out what’s causing this? And more importantly, has OpenAI acknowledged that the issue has returned?

I really don’t want this to become something we have to keep dealing with every couple of weeks.

You’re not the only one who has this problem, with my chats it also appears

Seeing reports like this lately. This seems like a problem with the server rather than how context is normally used, especially when it happens in brand-new chats. Does OpenAI fully agree with this yet?
