@Yao_Zhang Hey thanks for reporting this, and sorry for the disruption.

This is a known regression affecting Opus 4.6, 4.7, and a few other 1M variants — chats are getting capped/summarized around 200–300K instead of 1M. A fix is rolling out now, so things should be back to normal shortly. Restarting Cursor once it lands will pick it up. I’ll respond here once we’ve confirmed the fix.
