Tested Cosmos (both 14B and 2B). The model appears to have a better understanding of the world. Some notes:
Messes up hands/fingers more often than Flux 1 dev.
Seems like an improved dev, but so is HiDream.
But actually, it messes up hands and faces more often than Dev.
It's censored, so like all models that are censored it is hard to steer (Chroma in comparison is very easy to steer any way you want).
I found it to be slightly worse at prompt adherence than Dev.
I do not see much advantage over something like HiDream.
It is definitely slopped.
For 14B I tested fp8 version (pic rel).
