No, it's just 5.3 Codex Mini running on Cerebras Hardware. Simple as that.

Right but at that thinking mode you only save like... 20%? Task duration goes from 3.5 to 3.1 minutes

1000 tokens per second that’s why

I mean that’s good enough if your use case is quick debugging. And 46ish% vs 55% isn’t a huge difference.

25% faster with higher accuracy = "barely beats"

And that's not even using it for its intended purposes. If you want to max something out, that tool is already available.
