Beyond the inline findings, I checked whether removing the global truncation=False default from InputProcessingContext.call_hf_processor (vllm/multimodal/processing/context.py) regresses MiniCPM-V's _call_hf_processor_on_prompts, which calls call_hf_processor directly with real prompt text rather than going through the new dummy-text injection path. The underlying MiniCPMVProcessor.__call__/MiniCPMOProcessor.__call__ default their truncation kwarg to None (not True), so no truncation strategy is applied by default even without the removed global override — this path is not affected.
Extended reasoning...
Checked the one candidate beyond the two confirmed inline findings (ovis.py missing _get_hf_mm_text, voxtral.py re-reversing the audios->audio remap): whether dropping the global truncation=False default in context.py's call_hf_processor affects MiniCPM-V, since its _call_hf_processor_on_prompts calls call_hf_processor directly with real prompt text instead of through the new dummy-text-triggered truncation=False injection. Verified vllm/transformers_utils/processors/minicpmv.py and minicpmo.py both default their truncation parameter to None, so the tokenizer applies no truncation strategy by default regardless of the removed global kwarg — this path is unaffected. Separately (not part of the spoken note, since it doesn't need re-stating for the author), I also re-checked the four issues raised in my prior review round (molmo2.py missing _get_hf_mm_text/guard, transformers/multimodal.py missing guard, deepseek_ocr.py text->prompt rename, qwen2_5_omni_thinker.py missing _get_hf_mm_text, moss_transcribe_diarize.py empty-hf_data guard, and the _cached_apply_hf_processor performance regression) and confirmed all were fixed in the subsequent commits (0f818a1, 63f78ed, 147c1b5, 814c89f) — these are resolved, not restated here per the no-redundancy rule.
Additional findings (outside the current diff — GitHub can't attach inline comments there):
-
🔴
vllm/model_executor/models/ovis.py— Commit 0f818a1 ("Remove unnecessary overrides", part of this PR) deleted OvisMultiModalProcessor._get_hf_mm_text (which returnedIMAGE_TOKEN * num_images), assuming the override just duplicated default no-op behavior. But vllm/transformers_utils/processors/ovis.py's OvisProcessor.call only attachespixel_values/gridsto its returned BatchFeature inside theif text is not None:branch (otherwiseimage_featuresonly holdsimage_placeholders) -- unlike the sibling Ovis2_5Processor, whose__call__assignsoutput["pixel_values"]/output["grids"]unconditionally whenever images are given. So dropping the dummy text is not a no-op for plain Ovis.Extended reasoning...
Any request with an image to an Ovis (non-2.5) model: base
_get_hf_mm_inputsnow calls_get_hf_mm_text, which returns None (no override left), so notextkey is added to hf_data._call_hf_processorinvokesOvisProcessor(images=[...], return_tensors='pt')with notextkwarg. InsideOvisProcessor.__call__, sincetext is None, it returnsBatchFeature(data=image_features)whereimage_featuresonly containsimage_placeholders--pixel_valuesandgridsare never attached. Back inOvisMultiModalProcessor._postprocess_hf_mm_data(ovis.py:345-357),mm_data(hf_data) is non-empty so the early-return guard at line 351 doesn't trigger, and line 357 doesfor grid in processed_data["grids"], raisingKeyError: 'grids'-- every image-bearing Ovis request crashes.Verification: Severity: normal — this PR introduces a crash the base branch does not have. The ovis.py diff deletes
OvisMultiModalProcessor._get_hf_processor_text(which returnedself.dummy_inputs.get_dummy_text(mm_counts)=IMAGE_TOKEN * num_images, non-None). No_get_hf_mm_textoverride replaces it, andOvisMultiModalProcessorextendsBaseMultiModalProcessordirectly. The refactored base `get_hf

Remove videos after the custom video path.
When this branch processes videos, it leaves hf_data["videos"] intact. Line 1677 then sends the raw videos to the final HF processor together with the prompt that already contains the generated video placeholder. The final processor can process the videos a second time, which makes its input_ids inconsistent with the separately collected video_outputs.
Pop videos when this branch binds the local videos variable.

Hugging Face Transformers PaddleOCRVLProcessor input_data_format images_kwargs __call__ source
💡 Result:
In the Hugging Face Transformers library, the PaddleOCRVLProcessor handles the preparation of multi-modal inputs, specifically processing images and text for models like PaddleOCR-VL [1][2]. The call method of PaddleOCRVLProcessor acts as the primary interface for preparing inputs [1][3]. It signature is defined as [1]: def call( self, images: ImageInput = None, text: TextInput | PreTokenizedInput | list[TextInput] | list[PreTokenizedInput] = None, kwargs: Unpack[PaddleOCRVLProcessorKwargs],) -> BatchFeature: Key technical details regarding your query include: 1. Handling of kwargs and images_kwargs: The processor uses a mechanism to merge keyword arguments using _merge_kwargs [4][5]. When processing images, it extracts specific configuration from the provided kwargs and delegates the actual image processing to the internal image_processor [4][5]. Specifically, arguments intended for image processing are passed via the images_kwargs dictionary, which is extracted during the merge process [4][5]. 2. input_data_format: This parameter is typically passed down to the underlying PaddleOCRVLImageProcessor [6]. It defines the channel dimension format of the input images [6]. If left as None, the processor will automatically infer the format from the input image (e.g., "channels_first" for (num_channels, height, width) or "channels_last" for (height, width, num_channels)) [7][6]. 3. Source Code Reference: The core implementation is found in the Transformers repository under src/transformers/models/paddleocr_vl/processing_paddleocr_vl.py [1][5]. The call method processes images first (if provided) to obtain pixel_values and image_grid_thw, then subsequently processes text, performing token replacement for image placeholders based on the grid dimensions returned by the image processor [1][4]. For a complete list of supported arguments, you can refer to the PaddleOCRVLProcessorKwargs TypedDict definition within the library source code [8][2].

💡 Result:
In the Hugging Face Transformers library, specifically within the PaddleOCR-VL model implementation, input_data_format and images_kwargs are parameters used in image processing workflows to manage data structures and dynamic configuration [1][2]. input_data_format This parameter specifies the channel dimension format of the input image [1][2]. It accepts a string or a ChannelDimension object [2]. If left unset (None), the processor typically attempts to infer the format automatically from the input image [2]. Supported formats include: - "channels_first" or ChannelDimension.FIRST: Represents images in (num_channels, height, width) format [1][2]. - "channels_last" or ChannelDimension.LAST: Represents images in (height, width, num_channels) format [1][2]. - "none" or ChannelDimension.NONE: Represents images in (height, width) format [1][2]. images_kwargs This is an optional dictionary used to override default image processor configurations dynamically, particularly during operations like calculating image patches [1]. Methods such as get_number_of_image_patches utilize this argument to allow users to pass custom values for parameters like: - min_pixels: Defaults to the shortest_edge setting if not provided in the dictionary [1]. - max_pixels: Defaults to the longest_edge setting if not provided [1]. - patch_size: Overrides the default patch size attribute [1]. - merge_size: Overrides the default merge size attribute [1]. These parameters ensure flexibility when dealing with varied input formats or when specific model preprocessing requirements (such as dynamic image sizing) necessitate ad-hoc adjustments [1][3].

Pass final_mm_kwargs to call_hf_processor.
PaddleOCRVLMultiModalProcessor constructs the processor with final_mm_kwargs but invokes it with the original hf_kwargs. call_hf_processor forwards only its third mapping to PaddleOCRVLProcessor.__call__, so input_data_format=ChannelDimension.LAST is not applied during image processing. Construct the processor with hf_kwargs and pass final_mm_kwargs as the third argument.

In `@vllm/models/minimax_m3/common/mm_preprocess.py` at line 358, Update the
kwargs merge in the MiniMax preprocessing flow so the `do_resize` default is
applied without duplicate-key errors when `hf_kwargs` already contains it. In
the construction of `merged`, merge `hf_kwargs` first and then override
`do_resize` to true, preserving forced resizing for raw-frame inputs.

Processing result and prompt flow

for it in one value throughout cached and uncached processing.
Normalized HF processor inputs
HFMultiModalInputsgroups the three values used by HF processing:_get_hf_mm_dataand_preprocess_hf_mm_dataare replaced by_get_hf_mm_inputs(mm_items, hf_kwargs). The new method:_get_hf_mm_text;hf_data;truncation=Falsewhen dummy text is passed, unless explicitlyoverridden by the caller;
audioskey to the HFaudiokeyword; and_get_hf_processor_textis renamed to_get_hf_mm_text. Models whose HFprocessors require matching text and media now override this method instead of
generating dummy text inside
_apply_hf_processor_main. This ensures that thedummy text and
truncation=Falseare installed together.Processors that use the nonstandard plural
audioskeyword, including Phi-4Multimodal and Dots3Note, remap
audioback toaudiosin their_get_hf_mm_inputsoverrides.HF call and finalization hooks
The base processor now splits its execution into four hooks:
_get_hf_mm_inputsnormalizes inputs._call_hf_processorperforms the HF invocation._finalize_hf_mm_datamerges passthrough fields._postprocess_hf_mm_datatransforms the combined output._finalize_hf_mm_dataacceptsprocessed_data=Noneand lazily constructs anempty
BatchFeature, avoiding empty allocations at no-data call sites.The
_call_hf_processorhook allows models to customize the callable or usedifferent construction and invocation kwargs without reimplementing the whole
application method. It removes custom
_apply_hf_processor_mainoverrides for:Earlier migrations also remove the override for Ernie 4.5 VL, Phi-4
Multimodal, Qwen2.5-Omni/Qwen3-Omni, and Ultravox by moving their behavior into
input normalization and output postprocessing. Ultravox removes the centrally
injected
truncationargument because its remote processor already hardcodestruncation=Falseand otherwise forwards a duplicate argument.The remaining model-specific
_apply_hf_processor_mainimplementations aregenuinely multi-stage or manually construct processor outputs. They still
follow the base contract: every implementation calls
_get_hf_mm_inputs, andevery outer return path calls
_finalize_hf_mm_data.Keyword and audio behavior
InputProcessingContext.call_hf_processorno longer globally defaultstruncation=False. Applying it only alongside dummy text prevents unrelated HFprocessor calls from receiving a text-specific option.
The central
audiostoaudionormalization matches current Transformers HFprocessor signatures. Model-specific compatibility remaps are retained where a
remote or custom processor still expects
audios.Cache handling
The cache-miss data builder skips modalities with no missing indexes. This
prevents empty modality entries from reaching model processors while preserving
the existing cache behavior for actual misses and passthrough data.
