* initial gemma4 support

* parity with reference implementation

outputs can 100% match transformers with same sdpa flags, checkpoint this and then optimize

* Cleanup, video fixes

* cleanup, enable fused rms norm by default

* update comment

* Cleanup

* Update sd.py

* Various fixes

* Add fp8 scaled embedding support

* small fixes

* Translate think tokens

* Fix image encoder attention mask type

So it works with basic attention

* Handle thinking tokens different only for Gemma4

* Code cleanup

* Update nodes_textgen.py

* Use embed scale class instead of buffer

Slight difference to HF, but technically more accurate and simpler code

* Default to fused rms_norm

* Update gemma4.py

Implement block prefetch + Lora Async load + and adopt in LTX (Speedup!) (CORE-111) (#13618)
* mm: Use Aimdo raw allocator for cast buffers

pytorch manages allocation of growing buffers on streams poorly. Pyt
has no windows support for the expandable segments allocator (which is
the right tool for this job), while also segmenting the memory by
stream such that it can be generally re-used. So kick the problem to
aimdo which can just grow a virtual region thats freed per stream.

* plan

* ops: move cpu handler up to the caller

* ops: split up prefetch from weight prep block prefetching API

Split up the casting and weight formating/lora stuff in prep for
arbitrary prefetch support.

* ops: implement block prefetching API

allow a model to construct a prefetch list and operate it for increased
async offload.

* ltxv2: Implement block prefetching

* Implement lora async offload

Implement async offload of loras.

* pinned_memory: remove JIT RAM pressure release

This doesn't work, as freeing intermediates for pins needs to be
higher-priority than freeing pins-for-pins if and when you are going
to do that. So this is too late as pins-for-pins is model load time
and we dont have JIT pins-for-pins.

* cacheing: Add a filter to only free intermediates from inactive wfs

This is to get priorities in amongst pins straight.

* mm: free inactive-ram from RAM cache first

Stuff from inactive workflows should be freed before anything else.

* caching: purge old ModelPatchers first

Dont try and score them, just dump them at the first sign of trouble
if they arent part of the workflow.

ModelPatcherDynamic: force cast stray weights on comfy layers (#13487)
the mixed_precision ops can have input_scale parameters that are used
in tensor math but arent a weight or bias so dont get proper VRAM
management. Treat these as force-castable parameters like the non comfy
weight, random params are buffers already are.

fix: use Parameter assignment for Stable_Zero123 cc_projection weights (fixes #13492) (#13518)
On Windows with aimdo enabled, disable_weight_init.Linear uses lazy
initialization that sets weight and bias to None to avoid unnecessary
memory allocation. This caused a crash when copy_() was called on the
None weight attribute in Stable_Zero123.__init__.

Replace copy_() with direct torch.nn.Parameter assignment, which works
correctly on both Windows (aimdo enabled) and other platforms.

Fix/tweak pinned memory accounting (#13221)
* mm: Lower windows pin threshold

Some workflows have more extranous use of shared GPU memory than is
accounted for in the 5% pin headroom. Lower this for safety.

* mm: Remove pin count clearing threshold.

TOTAL_PINNED_MEMORY is shared between the legacy and aimdo pinning
systems, however this catch-all assumes only the legacy system exists.
Remove the catch-all as the PINNED_MEMORY buffer is coherent already.

wan: vae: Fix light/color change (#13101)
There was an issue where the resample split was too early and dropped one
of the rolling convolutions a frame early. This is most noticable as a
lighting/color change between pixel frames 5->6 (latent 2->3), or as a
lighting change between the first and last frame in an FLF wan flow.

Move inline comfy.context_windows imports to top-level in model_base.py (#13083)
The recent PR that added resize_cond_for_context_window methods to
model classes used inline 'import comfy.context_windows' in each
method body. This moves that import to the top-level import section,
replacing 4 duplicate inline imports with a single top-level one.

* Add slice_cond and per-model context window cond resizing

* Fix cond_value.size() call in context window cond resizing

* Expose additional advanced inputs for ContextWindowsManualNode

Necessary for WanAnimate context windows workflow, which needs cond_retain_index_list = 0 to work properly with its reference input.
