Describe the Bug

I’m seeing a bug with Opus 4.6 Max where the context meter is constantly stuck at 100% used.

This happens even after restarting Cursor and creating a completely brand-new chat. The moment the new chat opens, it already shows 100% context used, even with only a tiny amount of text in the conversation.

It also seems to start summarizing the chat context almost immediately, which makes the model basically unusable.

Has anyone else seen this with Opus 4.6 Max?

Steps to Reproduce

Try using any of the Opus 4.6 models within Cursor

Expected Behavior

The context is not being 100% used the moment you interact with it.

Operating System

MacOS

Version Information

Cursor version 3.0

For AI issues: which model did you use?

Opus 4.6

Does this stop you from using Cursor
