Auto Agent degredation?

Where does the bug appear (feature/product)?

Cursor IDE

Describe the Bug

Cursor auto agent is demonstrating prior version logic and bugs similar to that of GPT 5.2 and earlier. I would like to know what verstion logic is available for the cursor auto agent because the output is significantly changed and the drift is beyond measure. Agents will not follow basic instructions or markdowns as prescribed and drift if more than two sentences.

Steps to Reproduce

note that hyphens show up in most text generation, context limiting and inability to handle complicated or concurrent logic.

Expected Behavior

I expect this to work like it did prior, i fear that cursor rolled the agent logic back to save a penny and water down the value of the auto agents.

Operating System

Windows 10/11

For AI issues: which model did you use?

auto

Does this stop you from using Cursor

Sometimes - I can sometimes use Cursor

Hey, thanks for the report. A few users have mentioned something similar with Auto mode, and the team is aware.

Auto mode dynamically picks a model for the task, and that choice isn’t always ideal, especially for complex multi-step tasks. A couple things that might help:

  1. Try switching to Premium mode next to Auto in the model selector. It prioritizes quality.
  2. Or pick a specific model manually, like Claude Sonnet, Claude Opus, or GPT-5 for harder tasks.

If you want us to look into a specific case, send the Request ID (three dots in the top right of the chat > Copy Request ID). With that, we can check which model was picked and what went wrong.

Let me know how it goes.

this is occuring on every agent every time, ive gotten the premium selected, this just screams a downgraded model.

I got the same issue, and also mentioned several places.
Agents are down all over.
Even premium agents, either take a really long time, or most of the times time out.

It seems to run somewhat better today, but now i have to keep unlocking the agent for the background.
