I fear this is just the classic "nerf the model just before we release a new version of it"
I am now wondering
I use gemini for rewriting code docs, because the frontier models are so verbose when it comes to writing text
It made half the changes, committed and pushed, then it made the other half of the changes on the same two files as before and... just stopped and reported back with a cheerful "all good, all done and pushed".
Lets say it has gotten worse? What are you going to do about it? Jump to Codex? Then what happen if you perceive that to be getting worse? Jump back to Claude? One of the many problems with these tools.
