Agent in Auto response too long

Where does the bug appear (feature/product)?

Cursor IDE

Describe the Bug

Agent Auto mode works too slow sometimes. I also noticed that for slow requests, the reply appears extremely slowly—literally word by word.

Steps to Reproduce

Creating an empty project.

I start a new chat in Auto mode and type “hi.” The response takes a very long time, sometimes showing a “Taking longer than expected” message.

I start another new chat, select Composer 2 mode, and type “hi.” The response is very fast.

Occasionally, Auto mode starts working normally.

I’ve tried with and without VPN — the problem reproduces equally.
I’ve also tried switching to HTTP/1.1, but that doesn’t improve the situation.

Operating System

Windows 10/11

Does this stop you from using Cursor

Sometimes - I can sometimes use Cursor

Hey, this is a known issue. Auto mode goes through extra server routing steps that don’t happen when you pick a model manually, so the speed difference is noticeable.

The team is aware. For now, the workaround is to select the model manually, like you already noticed with Composer 2.

Let me know if anything changes.
