Wow, I have been using Open 4.6 and for the last 15 minutes, and it's already made two extremely stupid mistakes... like misunderstanding basic instructions and editing the file in a very silly, basic way. Pretty bad. Never seen this with any model before.
The one bone I'll throw it was that I was asking it to edit its own MCP configs. So maybe it got thoroughly confused?
I dunno what's going on, I'm going to give it the night. It makes no sense whatsoever.
I am also _not_ happy. I tried the `/model` command and I could not switch back to Opus 4.5. However, the command line option did let me set Opus 4.5:
``` claude --model claude-opus-4-5-20251101 ```
I will probably work with Opus 4.5 tomorrow to get some work done and maybe try 4.6 again later.
It was better today. I dunno if there was a regression in a corresponding cc version that was maybe quickly patched?
It felt like it was at least back to opus 4.5 levels.
To me its obvious.
Theres a trade off going on - in order to handle more nuance/subtleties, the models are more likely to be wrong in their outputs and need more steering. This is why personally my use of them has reduced dramatically for what I do.
