 In newer DiT-based ecosystems, you may also see AiO, short for all-in-one. AiO usually means the full generation stack is packaged together as one coordinated model release, often including the transformer or denoiser, text encoders, and VAE in the same bundled file or tightly coupled package.
 
-In many AiO releases, that really does mean a single bundled model file with the text encoder and or VAE included. The important nuance is that this is still not universal. Some modern DiT releases remain split into separate internal components, but are distributed and loaded as one complete package instead of expecting the user to assemble mismatched pieces manually.

 Why it matters: if a model is VAE-baked, setup is simpler because you do not need to hunt for a matching external VAE. If a model is described as AiO, it usually means setup is simpler at a broader level because the main transformer, text encoders, and VAE are meant to be used together as one packaged release. That said, not all DiT models are AiO, and many modern ones remain modular by design for flexibility, swapping components, and memory management.
