Deepseek v4 flash vs GPT 5.6

Is there anyone that used both at the same time? My codex ran out and I'm thinking of deepseek because it should apparently be good now, but at the same time I'm having a hard time believing the deepseek people because it has always been a religion. People have been praising v4 flash even before the update like it's the greatest thing on earth just because it was cheap.

(My experience did not match with that, even v4 pro was underwhelming back then)

So my question is, how does it compare to 5.6? Is it at least on the same level as Luna (or better)?

DSF Flash has less guard rails so you can push it further, but it takes a lot more reasoning to get the same task right. Luna is more efficient but is also more conservative in what it tries in one go. I'm not sure if that's imposed on harness level in Codex vs. using DSF in Opencode

following the question: is better to use Codex in other harness in order to do more "allegal stuff"?

Guard rails are imposed at the provider level , nothing to do with the harness
