Also the chat limit for free-tier isn't the same anymore. A few months ago it was still behaving as in Claude: beyond a certain context length, you're politely asked to subscribe or start a new chat.

Starting two or three weeks ago, it seems like the context limit is a lot more blurry in ChatGPT now. If the conversation is "interesting" I can continue it for as long as I wish it seems. But as soon as I ask ChatGPT to iterate on what it said in a way that doesn't bring more information ("please summarize what we just discussed"), I "have exceeded the context limit".

Hypothesis: openAI is letting free user speak as much as they want with ChatGPT provided what they talk about is "interesting" (perplexity?).
