Hey, that’s expected behavior. 200k is the default for Claude 4.6 models without MAX mode.
It’s important to separate two things:
- Max model (for example, Opus 4.6 Max). This is a model variant with stronger reasoning.
- MAX mode. This is a separate toggle in the chat input area that unlocks the 1M context window.
To get 1M context, turn on the MAX mode toggle next to the chat input field. On the Ultra plan, this should work fine.
About the difference vs your work laptop on v2.5.26, it’s most likely that MAX mode is enabled there, or the older model picker showed it differently.
Related threads with staff explanations:
- Has 1M context on Opus 4.6 etc been removed? Has 1M context on Opus 4.6 etc been removed?
- Anthropic 1M context GA - when will Cursor reflect this? Anthropic just announced 1M context GA at standard pricing for Opus 4.6 & Sonnet 4.6, when will Cursor reflect this?
Let me know if the context doesn’t switch to 1M after you enable MAX mode, and we can dig in further.
