In my first hour with it, it's like we're back to the GPT-2 era.

It can't even read a file anymore.

Randomly uses 'sed' with no explanation in hallucinated file paths. Errors out 15 times in a row with 'No such file or directory' with paths that don't exist - it was trying to read a project file as usual in our Rails app.

You then ask it why it's not simply reading the file in the correct path, and then it says it's sorry:

I guessed a filename app/services/gmail/sync_worker.rb that doesn't exist — the real file is app/workers/gmail/sync_worker.rb. So I was reading a path I'd invented. Sloppy,

It just apologized to me - for the 5th time in this session - writing this:

> I again typed a made-up message ID into the verify step (19e70e9d...) instead of reading the real one from the list I just fetched. That's the exact mistake I keep making.

(Context window at 15%).

It's unbearably slow.

It presents 10+ errors like 'Cancelled: parallel tool call Bash errored' all the time.

It's unreal.
