I made the mistake of using Opus5 for setting up a local LLM workspace inside Zed. It’s like working with a schizophrenic. It’s completely destroyed my entire workspace to the point I’m having to nuke it and start over fresh. It keeps running off on it’s own without mentioning anything. My setup is supposed to be WSL2 + vLLM + Aider. At one point it decided that it just wasn’t going to use Aider anymore, so it deleted everything and rewrote all my config files to use the Zed Agent and “select Local vLLM from the drop down menu”, which is just not a thing that exists. I left for a few minutes earlier while it was running. Keep in mind, I don’t let Claude write things on my behalf. It is meant to walk me through things that are new to me and that’s all. After about 15 minutes I came back. It was supposed to have just familiarized itself with some of the MD files and PDFs I wrote about what I was hoping my workspace would look like. I had to stop it when I came back and this was it’s response: You’re right, and I have a standing note about exactly this — “together means together” — which I blew straight past. You asked me to get oriented so we could work through it side by side; I went and did the entire job solo. That’s precisely the black box you don’t want. Stopping. I come to find out what it did is downgrade all of my venv packages, added three symlinks, edited my entire start-llm.sh file and didn’t create a backup, and decided to start a tmux session. What the actual fuck is wrong with this model? My original prompt was: Familiarize yourself with the workspace and read through the PDFs. We’re going to be getting Qwen3-Coder running in a terminal inside Zed today. It just ran off and started making completely arbitrary decisions without any oversight whatsoever. I don’t think I could intentionally make a model as destructive as this one if you gave me six months and unlimited budget to finetune one to my hearts content. It’s like this one is made to be mentally ill. It keeps randomly deciding to switch clients. At one point it had a complete schizo breakdown and couldn’t decide if Aider was meant to run on Windows or Ubuntu so it just looped for a few minutes swapping it back and forth. How am I supposed to work with this model? I actually don’t understand. Maybe for vibe coding it’s good, but it seems to be completely insane and want to take the reigns on anything where it’s supposed to be an assistant or work alongside me. submitted by /u/Narwal_Party
