The refine toggle doubles as the slot selector on the UNet/DiT page:
with it active a card click sets sd_unet_secondary instead of sd_unet,
mirroring base/refiner selection on the model page.
The secondary unet loads from the networks panel toggle or the settings
page; companion ordering and dynamic visibility pushes in ui_settings.py
are not worth their footprint for one setting.
The hidden change_refiner button passed key='sd_model_checkpoint', so
loading a card with the refine toggle active reloaded the base model
and never set sd_model_refiner.
One UNET override cannot serve dual-transformer arches: ideogram4
conditional/unconditional and wan combined-stage experts need separate
files, and previously a single override landed on both experts.
- sd_unet_secondary option with per-slot tracking, consumed-state sync,
arch-change reset, and incompatible-override fallback
- dropdown renders beside the primary, follows it into quicksettings,
and is visible only for dual-transformer model types
- ideogram4 native single-file spec with a quant-aware fused-qkv
converter; such converters run before comfy_quant detection via
TransformerSpec.converter_handles_quant
- quicksettings render in configured order (sort keyed on the option
object and always fell back to alphabetical)
- post-load dtype warning skips quantized transformers
When a checkpoint change switches the model type, a custom sd_text_encoder no
longer fits, so reset it to Default and clear loaded_te, mirroring the sd_unet
reset. The type is resolved with detect_pipeline on both the loaded and incoming
checkpoints, so same-arch switches (Krea2 Base and Turbo share one pipeline
class) do not reset. The checkpoint handler also returns sd_text_encoder
alongside sd_unet so the dropdown reflects it.
reload_text_encoder only hot-swapped T5-family encoders and ran only at initial
load, so changing sd_text_encoder for a model with a generic encoder (Krea2's
Qwen3-VL) never took effect until a full model reload. Track the loaded
selection and, for encoders with no in-place swap, reload the model on change,
triggered from the settings handler. The fresh model object also invalidates
the prompt cache.
When reload_model_weights resets shared.opts.sd_unet to Default on a cross-arch swap, the backend value changed but the dropdown component kept showing the previous selection because sd_unet was not in the change_checkpoint button's outputs.
Add the sd_unet component to the outputs and return its post-reload value via gr.update.
Editable dropdowns (sd_model_checkpoint, sd_text_encoder) fired a
.change event on every keystroke because Gradio's allow_custom_value
keyup handler sets the value to the typed text.
- Use .blur instead of .change for DropdownEditable in quicksettings
- Validate model keys in run_settings_single before committing
