I work exclusively with Opus4.5 thinking in a complex project. The last days the results are not as good as in former days. Ai does not often deliver good quality. I read that 2.4.28 has bigger issues. So before spending more time and money i would like to downgrade to 2.4.27.
What are your suggestions? Work temporary with Opus 4.5 without “thinking” or better GPT5.2?
Is 2.4.27 a more stable version?
Where can i find the download link?
Thanks, Thomas
Here you should be able to download older versions

What gives you the impression that cursor has anything to do with it? I’ve seen a report and from personal experience as well that Opus 4.5 is performing poorly lately. FWIW Sonnet 4.5 seems worse as well. Again my own anecdote.
