Where does the bug appear (feature/product)?
Cursor IDE
Describe the Bug
In last few days the model responses in the agentic mode became very slow (Opus 4.5, Sonnet 4.5, etc). It takes forever in “Plannin next steps”. I restarted Cursor also checked other IDEs like Antigravity, so there are no issues with my connection, etc.
Steps to Reproduce
Just run request in teh agent window
