Hey, this is expected behavior, I’ll explain.
There’s an important difference: the Max model like Opus 4.6 Max is a variant with stronger reasoning, while MAX mode is a separate toggle that unlocks the 1M context window. These are two different things.
The 1M context window is only available via MAX mode, which requires a paid plan (Pro/Ultra/Team/Enterprise).

- Has 1M context on Opus 4.6 etc been removed? Has 1M context on Opus 4.6 etc been removed?
- Anthropic just announced 1M context GA… Anthropic just announced 1M context GA at standard pricing for Opus 4.6 & Sonnet 4.6, when will Cursor reflect this?
If you upgrade to a paid plan and turn on MAX mode using the toggle in the chat input area, 1M context should become available.
If you’ve got more questions, let me know.
