JoyImageEditPlus is the multi-image (1-6 reference images) variant of
JoyImageEdit, trained from the same base. Its diffusers transformer shares
byte-identical weight structure with the single-image variant (894 keys, zero
rename) but injects references differently: instead of the single-image
slot-stack (stack refs + noise into a 6D tensor and rotate on the frame dim,
which forces all items to share resolution), each reference is independently
patchified and concatenated on the sequence dim with per-image temporal-offset
3D RoPE, allowing references at different resolutions.
Since the single-image port is not yet upstream, this unifies both variants
onto the Plus-style forward rather than keeping two paths; single-image is now
the ref=1 special case. Verified numerically: at ref=1 with equal resolution
the new path's RoPE is bit-identical to the old slot-stack layout, and the
transformer output matches the diffusers Plus reference (fp32, incl. the
different-resolution case).
ComfyUI runs cond/uncond in one forward with a shared reference configuration,
so the diffusers Plus batched RoPE, padding attention_mask, and dedicated
attention processor are unnecessary here: the unified forward reuses the
existing unbatched _apply_rotary_emb and JoyImageAttention. Confirmed
equivalent to the diffusers batched+mask path for a single sample.
- comfy/ldm/joyimage/model.py: forward takes ref_latents and builds
components=[target, ref0, ...]; per-component patchify + temporal-offset
RoPE; output keeps only the target segment. Old single-grid RoPE removed.
- comfy/model_base.py: JoyImage drops the slot-stack / frame-rotation /
shape-equality path in _apply_model, passing ref_latents straight to the
transformer. Guidance-rescale and the reference_latents requirement are kept.
- comfy/text_encoders/joyimage.py: the image template emits one vision block
per reference (N = image count); N=1 is byte-for-byte the old template.
- comfy_extras/nodes_joyimage.py: add TextEncodeJoyImageEditPlus with optional
image1..image6 inputs, each bucket-resized and VAE-encoded into the
reference_latents list.
Detection, supported_models, and sd.py need no changes: the identical weight
structure routes both variants through image_model="joyimage".
Add a --enable-asset-hashing CLI flag (action=store_true, default False)
and plumb it into the two asset-seeder call sites in main.py that
previously hardcoded compute_hashes=True (the startup scan and the
post-job output enqueue). Local runs now skip blake3 hashing unless the
user opts in, avoiding the startup/per-output cost on large models
directories while keeping hashing available for asset-portability
features.

Upstream merged native Qwen3-VL support (#14298), adding
comfy/text_encoders/qwen3vl.py plus helpers in qwen_vl.py / llama.py /
qwen35.py. The JoyImage port previously shipped its own duplicate
Qwen3-VL implementation (comfy/text_encoders/qwen3_vl.py); that
duplication is now removed and the JoyImage text encoder rides on the
upstream stack.
- Delete comfy/text_encoders/qwen3_vl.py.
- Rewrite comfy/text_encoders/joyimage.py to subclass upstream
comfy.text_encoders.qwen3vl. The JoyImage checkpoint is a stock
qwen3vl_8b, so only JoyImage-specific behavior is overridden:
* Qwen3VL8B_JoyImage.forward builds the 3D MRoPE position ids and
injects deepstack visual features on the conditioning path. Upstream
Qwen3VL only does this inside generate() via build_image_inputs;
SDClipModel.forward never passes those kwargs. The JoyImage node
feeds an image through the encoder (clip.tokenize(prompt, images=[..])),
so the override reuses build_image_inputs to reproduce the multimodal
conditioning that Llama2_.forward already accepts kwargs for.
* preprocess_embed keeps JoyImage's bicubic+clamp image preprocessing
(process_qwen3vl_image) instead of upstream's bilinear path, to
preserve validated DiT numerics.
* JoyImageTokenizer keeps the JoyImage system-prompt templates,
suppresses the Qwen3 <think> block, and raises on image-placeholder
count mismatch.
* JoyImageTEModel keeps the drop_idx=34 system-prompt strip and the
pre-final-norm layer tap (layer="hidden", layer_idx=-1).
- sd.py QWEN3VL_8B_JOYIMAGE branch: apply the same state-dict prefix
remap the sibling QWEN3VL branch uses (model.language_model.->model.,
model.visual.->visual., lm_head.->model.lm_head.) so the checkpoint
loads into the upstream Qwen3VL namespace, then use the module-level
llama_detect. Detection ordering is preserved: the JoyImage
discriminator is checked before the generic Qwen3-VL deepstack key.
No changes to llama.py / qwen3vl.py / qwen_vl.py / qwen35.py.
JoyImageEdit is an image-edit diffusion transformer from JD (jd-opensource),
Apache 2.0. This adds native ComfyUI support so it loads and runs like other
edit models (load checkpoint -> TextEncode + ReferenceLatent -> KSampler ->
VAEDecode), with no diffusers dependency.
Architecture:
- Transformer (comfy/ldm/joyimage/model.py): dual-stream (img/txt) DiT with a
Conv3d patch embed (patch_size [1,2,2]), Wan-style learnable modulation,
and 3D RoPE (rope_dim_list [16,56,56]). All attention goes through
comfy.ldm.modules.attention.optimized_attention.
- Text encoder (comfy/text_encoders/{qwen3_vl,joyimage}.py): a reusable
Qwen3-VL multimodal stack (vision tower + LM) in qwen3_vl.py, plus a thin
JoyImage-specific layer (prompt templates, drop_idx, tokenizer, te() factory)
in joyimage.py that depends on it. text_dim 4096.
- VAE: reuses the existing Wan 2.1 latent format (AutoencoderKLWan), no new
latent format.
- Edit conditioning: reuses the reference_latents mechanism. Reference and
noise latents are stacked on a new n-slot dimension and rotated at the model
boundary (model_base.JoyImage), so the transformer stays 5D-in/5D-out.
Guidance-rescale is built into the CFG path.
Model wiring:
- model_base.JoyImage uses ModelType.FLOW with sampling_settings
multiplier=1000 (the time embedding is trained on t in [0,1000]) and
shift=1.5; FLOW's linear time_snr_shift matches the diffusers
FlowMatchEuler sigma schedule.
- model_detection sniffs the transformer state-dict (double_blocks.*,
condition_embedder.*, 5D img_in Conv3d) to route image_model="joyimage".
- supported_models.JoyImage and the CLIPLoader "joyimage" type register it.
User-facing node TextEncodeJoyImageEdit (comfy_extras/nodes_joyimage.py)
bucket-resizes the input image to the nearest 1024-base bucket, encodes the
prompt with the image, and emits both the conditioning and the bucketed image
so the same pixels feed VAEEncode and the negative encode (JoyImage requires
noise and reference latents to share spatial dims).
* main: implement --vram-headroom
Implement --vram-headroom for dynamic vram as a hybrid debug/diagnostic
option that can be used for people who still report shared VRAM spills.
They can trial and error the setting to maintain a bit more headroom to
avoid shared VRAM spills.
* main: implement --reserve-vram
Implement --reserve-vram as extra headroom on the simple method which
is semantically as close as possible to the stated functionality and
formet behaviour of non-dynamic VRAM.
Add this option for users who know they have so much ram they want
to pin everything or have a pagefile that outruns their disk speed.
The removes the RAM pressure caps completely and pins behind the
primary model load forcing all models to be permanently comitted
to RAM.
Some custom nodes .to weights completely out of load context which
can wreak havoc if its for a model that is not active. Detect this
condition and just let it fall-through to the non-dynamic loader
straight up.
Some custom nodes try to set this true globally. It messes with dynamic
VRAM with one-off spikes that can OOM but this is also very high risk
for windows where such allocations might get serviced by shared memory
fallback.
Trump it.
cleanup_models_gc can be called once per load_models_gpu via
free_memory, which in turn can de-activate an active model via
this reset_cast_buffers.
cleanup_models_gc() could also come via obscure garbage collector
paths so limit reset_cast_buffers to the post-node callsite instead.
* mm: split off registration helper to doer and headroom calc
* pinned_memory: implement registration comfy side
Move away from Aimdo buffer registrations which seem fraught with
danger and do it comfy side. Just start with the basic move.
* pinned_memory: do registrations as portable memory
* pinned_memory: discard async errors on registration fail
Like the good ol days.
* pinned_memory: implement abs shortfall retry
If pinned registration happens to fail despite the previous budget
ensures, consider the allocation shortfall, ensure it again, and
try again. This allows comfy pins to interoperate with other software
that might be doing substantive pinning.
* fix (MultiGPU): prevent freeze on manual abort when using MultiGPU CFG Split
Problem:
Upon manual abort application hangs indefinitely.
`InterruptProcessingException` inherits from `BaseException` and bypasses MultiGPU's worker error handling block so thread dies silently, leaving the main thread waiting forever for `result_q.get()`
Fix:
Catch `comfy.model_management.InterruptProcessingException` instead of `Exception` so it's caught and passed back via `result_q` to unblock the main thread when manual abort signal fires.
* oops
