When using a specific model (e.g., Claude 4.5), switching between modes (Ask ↔ Agent) causes the model selection to reset to Composer 1 instead of persisting my choice. Forces manual re-selection every time which sucks.
Steps to Reproduce
Steps to Reproduce:
Open Cursor Chat / Composer.
Select Haiku 4.5
Switch modes (e.g., from “Ask” to “Agent” or vice-versa).
Observe the model dropdown.
Expected Behavior
The selected model (claude-haiku) should persist across mode switches.
Operating System
MacOS
Current Cursor Version (Menu → About Cursor → Copy)
This is a known issue with model selection persistence when switching modes. The team is working on a fix.
As a temporary workaround, you can set the default model for each mode separately. In the model selection dropdown, there’s a setting where you can specify the default model for Ask, Agent, and other modes - then each mode will use its preset model.

For me its even worse… I go into Plan Mode, I select the model ie opus 4.5, type my prompt and hit enter… then Cursor switches to composer 1 and I have to stop, change it back and hit enter again… only then it works!
