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.
strptime was handed the stat datetime instead of the date string, so it
always failed and left a raw string mtime; the Date sort then crashed on
mixed str/datetime items. Parse the date string, falling back to stat mtime.
CivitAI has no model type for a standalone transformer, so DiT finetunes
are published as 'Checkpoint' like full models and all landed in
Stable-diffusion, where the single-file transformer loader never looks.
Route Checkpoint downloads to UNET unless the base model is a known full
checkpoint (SD1.x/2.x, SDXL and its Pony/Illustrious/NoobAI derivatives,
SVD, Kolors, Stable Cascade). Downloads with no base_model, or a
civitai_save_type_folders override, keep the previous behavior.
An absolute 1024-byte floor rejected valid complete downloads, since
some safetensors are legitimately tiny (a lone projector-diff tensor is
~160 bytes). Verify completeness against the declared Content-Length
instead, accepting any size, and keep the floor only as a fallback when
it is missing. Reject text/* responses up front so an HTML error or
login page served with HTTP 200 is never saved as a model file.
The LTX tab already collected a last-frame image but anchored every condition at index 0, so it never acted as a last frame. Build a separate condition for it at the final frame: index -1 for the 2.x family (latent index, negatives wrap) and num_frames-1 for 0.9 (pixel index). The Last image input now shows only for Condition models, the pipelines that accept multi-frame conditioning.
The I2V path forwards a last-frame image to the pipeline when one is supplied and the loaded pipeline accepts it, turning the run into first-last-frame interpolation. supports_last_frame() gates on the pipeline taking a last_image argument and not running expand_timesteps, which conditions on the first frame only, so a model that cannot use a last frame logs a warning instead of silently ignoring it.
Wan 2.2 A14B ships a per-model boundary_ratio (0.9 I2V, 0.875 T2V) that selects the high- or low-noise expert per step. The video and base-model image loaders both load the shipped value; the slider override is applied at generation time in set_pipeline_args, the one point both paths pass through before invoking the pipeline.
The denoising loop reads config.boundary_ratio each call, so tuning takes effect with no reload for video and base-model images alike. The slider defaults to -1, meaning use the model's value; 0 to 1 set the boundary explicitly. Single-expert stages stay load-time because they drop a transformer to free VRAM.
A single handler bound to the AR dropdown, width and height (in the
shared create_resolution_inputs and the resize section) wrote both
sliders on every change. With a ratio selected it locked one axis and
snapped it back on each edit, the two sliders looped, and the math ran
server-side one round-trip per keystroke, echoing a value back into the
field being typed in and yanking it.
Move aspect-ratio linking to the browser (ui/resolutionLock.ts): a
debounced edit writes only the partner axis, never the field being
edited, and commits immediately on blur, enter, or slider release. Keep
the kanvas notify on notifyKanvasResize wired to the resize sliders'
gradio .change, so it still fires on programmatic size updates (detect,
paste, swap) that client-side listeners miss. Drop the per-change AR
wiring, res_apply, and the resolutionChange* helpers.
