pipeline.model is a tagged union: a mapping with exactly one key, which names the model family (ltx2, minimax_h3, longcat, or generic) and selects that family's options class. The former sibling sections pipeline.ltx2, pipeline.minimax_h3, and pipeline.longcat, and the DiT/VAE architecture override dicts pipeline.dit and pipeline.vae, live inside the family block. The parser implements tagged unions as a general mechanism (a dataclass with a TAGS table); the family is readable as pipeline.model.family. Resolution validates the tag against the family that the registry chose for model_path (validate_model_family raises and names the registry class and the right block) and fills the family's empty block when the input has none (fill_model_family), so readers never see None. Family-only fills and derivations (the MiniMax-H3 parallel-VAE environment variables, the LTX-2 tile-size derivation and refine preset copy, the LongCat BSA mirrors) run only for their family. Against the3f6893a0goldens every PipelineConfig is identical and no other field differs beyond the allowed categories; family-only settings are no longer decided on models of another family. LingBot-Video reads its refiner switch from pipeline.preset_overrides.refine.enabled and loads the refiner by default when the checkpoint has one, as at3f6893a0.

In a realistic photography style, a white boy around seven or eight years
|
|
old sits on a park bench, wearing a light blue T-shirt, denim shorts, and
|
|
white sneakers. He holds an ice cream cone with vanilla and chocolate
|
|
flavors, and beside him is a medium-sized golden Labrador. Smiling, the
|
|
boy offers the ice cream to the dog, who eagerly licks it with its tongue.
|
|
The sun is shining brightly, and the background features a green lawn and
|
|
several tall trees, creating a warm and loving scene.
