I found Flash to be a bit shaky as well until I started using it in xhigh/max thinking effort, then it became my daily driver. It runs quite well on a couple of DGX Sparks.
I still wish it was a little better, but there's hope for another model checkpoint (maybe with some of GLM 5.2's goodness distilled into it, that would be nice).

This is true for most of the open weight chinese models, to be fair. They're really built around long reasoning chains.
Also you're making me want a second Spark-alike :') but they're so expensive...
