· 10 min read
vidax now ports nine model families, and no two of them make exactly the same architectural choices. Rather than write a separate deep-dive per model, this is a tour of the handful of ideas that, combined differently, account for most of the differences: the Diffusion Transformer (DiT) itself, how text and image conditioning get into it, and Mixture-of-Transformers — an architecture that isn't a DiT variant at all.
