Not at the moment apparently. They remove the thinking messages when you continue after 1 hour. That was the whole idea of that change. So the LLM gets all your messages, its responses etc but not the thinking parts, why it generated that responses. You get a lobotomised session.

OK didn't know that. I also resume fairly old sessions with 100-200k of context, and I sometimes keep them active for a while (but with large breaks in between).

Still on Opus 4.6 with no adaptive thinking, so didn't really notice anything worse in the past weeks, but who knows.

Or generate tiny filler messages every hour until you come back to it.
