Yeah I think the 1M context is the issue. Because I use Opus 4.6 through Cursor at the previous 200k limit and it has been totally fine. But if I switch to the 1M version it degrades noticeably.

I thought it was already well-known that context above 200k - 300k results in degradation.

One of my more recent comments this past week was exactly that - that there was no point in claiming that a 1m context would improve things because all the evidence we have seen is that after 300k context, the results degrade.

200k ought to be enough for anyone.
One could try:

> export CLAUDE_AUTOCOMPACT_PCT_OVERRIDE=50

Which will have Claude Code auto compact at ~500k window size.
