If you see one of their recent posts, they address this. They didn't expect the AI coding helper to be so popular which is why they had to use a cheaper, dumber model to keep costs down.

Unavoidable, considering the nature of the site's monetisation, which is to say, none.

EDIT: and to be fair, the AI has become more economical. It no longer rambles and goes off on tangents and thinking loops.

What it is now, is more of a tool than a companion, which is honestly fine for a coding helper.

You seem very... suspicious.

It's fake. The dev posts here, on Lemmy. Check out their most recent post, just a couple of days ago.

Nice, nice. Take your time, no worries.

Oddly enough, some generators still show the inner thinking in the coding chat.
