I dunno about that. Stable Diffusion is a good example. Some straight up better models, or breaking variants of SD, have come out, but the sheer amount of tooling and augmentations clamped onto Stable Diffusion has kept it dominant. Llama is another. The intertia and tooling has made MPT and Falcon, and all other non Llama architectures, basically irrelevant.
