Model choice in subagent sometimes not working appropriately

Where does the bug appear (feature/product)?

Cursor IDE

Describe the Bug

In cursor settings – Models page, users can select task model for subagents via explore subagent model, but sometimes subagents are not following the current choice. Is it a bug?

Steps to Reproduce

By using other models like gpt5.6 in plan, when I specify grok4.7 as subagents model, sometimes it will use gpt5.6 instead.

For AI issues: which model did you use?

It happens mostly when I use gpt5.6 sol.

Does this stop you from using Cursor

No - Cursor works, but with this issue
