The hottest model now is flux, and the community is gravitating toward it after the failure of stable diffusion 3.

Tooling around it is still nascent and it is very demanding (12GB+ VRAM GPU highly recommended) so you could also start with Stable Diffusion XL, fairly mature at this point.

This isn’t true anymore, Intel dropped AVX512 since they moved to Big+Small cores design while AMD actually implemented it with Zen 4.
