Tools failing and breaking chat with most models in agent mode

Bug Reports
1

In the last hour, pretty much everything I try in agent mode results in “User aborted request”, or some tool failure. Most recent example request ID: 0ec2e674-7609-4099-9a52-856418d17e03

So far I’ve tried the following models:

  • GPT-o3-mini
  • GPT-4o
  • Claude-3.7-sonnet
  • Claude-3.7-sonnet-thinking
  • Claude-3.5

In most cases, they work and call one or two tools (listing directories, grep, and web search only for my tests) successfully, then fail, and usually end up with the “User aborted request” error.

I’m not sure what’s going wrong, since most of these models were working fine up until this evening.

EDIT: I should add, that Claude’s models were what I tested with first, and often ended up stuck in “Generating” I thought perhaps that there were issues with Cursor’s agreements with Anthropic, so I tried my own API key, and it burnt through almost $50 in credits. So if you’re reading this and thinking the same, don’t.

I think it’s not the cursor version, I think it’s because of the AI models right?

I think it is likely due to the cursor version. I upgraded earlier today, and this problem wasn’t present before (last night and this morning).

After upgrading, agent mode is effectively broken for all of the models I listed.

Update: I reinstalled the “Latest” version of cursor (as per the download page) and Claude-3.7 appears to be working correctly. The thinking version still fails to use tools after one or two attempts.

Update: I can confirm that the latest update (via in app update prompt) breaks agent mode for all supported models…

Update: Reinstalling and updating again appears to have resolved this issue. I’ll marked this as solved, but the cursor team should really improve their release and versioning strategy.

I’m getting this intermittently on 0.46.4. Looks like 0.46.5 was just released but who knows what that covers!
