@@ + + + + +# T5Gemma + +T5Gemma (aka encoder-decoder Gemma) was proposed in a [research paper](https://arxiv.org/abs/2504.06225) by Google. It is a family of encoder-decoder large langauge models, developed by adapting pretrained decoder-only models into encoder-decoder. T5Gemma includes pretrained and instruction-tuned variants. The architecture is based on transformer encoder-decoder design following T5, with improvements from Gemma 2: GQA, RoPE, GeGLU activation, RMSNorm, and interleaved local/global attention. + +T5Gemma has two groups of model sizes: 1) [Gemma 2](https://ai.google.dev/gemma/docs/core/model_card_2) sizes (2B-2B, 9B-2B, and 9B-9B), which are based on the offical Gemma 2 models (2B and 9B); and 2) [T5](https://arxiv.org/abs/1910.10683) sizes (Small, Base, Large, and XL), where are pretrained under the Gemma 2 framework following T5 configuration. In addition, we also provide a model at ML size (medium large, ~2B in total), which is in-between T5 Large and T5 XL. + +The pretrained varaints are trained with two objectives: prefix language modeling with knowledge distillation (PrefixLM) and UL2, separately. We release both variants for each model size. The instruction-turned varaints was post-trained with supervised fine-tuning and reinforcement learning. + +The example below demonstrates how to chat with the model with [`Pipeline`] or the [`AutoModel`] class, and from the command line. + + + + + +```python +import torch +from transformers import pipeline + +pipe = pipeline( + task="text2text-generation", + model="google/t5gemma-placeholder", + torch_dtype=torch.bfloat16, + device="cuda", +) + +pipe("Question: Why is the sky blue?\nAnswer:", max_new_tokens=50) +``` + + + + +```python +import torch +from transformers import AutoTokenizer, AutoModelForSeq2SeqLM + +tokenizer = AutoTokenizer.from_pretrained("google/t5gemma-placeholder") +model = AutoModelForSeq2SeqLM.from_pretrained( + "google/t5gemma-placeholder", + torch_dtype=torch.bfloat16, + device_map="auto" +) + +input_text = "Question: Why is the sky blue?\nAnswer:" +input_ids = tokenizer(input_text, return_tensors="pt").to("cuda") + +outputs = model.generate(**input_ids, max_new_tokens=32) +print(tokenizer.decode(outputs[0], skip_special_tokens=True)) + +``` + + + + +``` +echo -e "Question: Why is the sky blue?

In this report, we present dots.llm1, a large-scale MoE model that activates 14B parameters out of a total of 142B parameters, delivering performance on par with state-of-the-art models while reducing training and inference costs. Leveraging our meticulously crafted and efficient data processing pipeline, dots.llm1 achieves performance comparable to Qwen2.5-72B after pretraining on high-quality corpus and post-training to fully unlock its capabilities. Notably, no synthetic data is used during pretraining. To foster further research, we open-source intermediate training checkpoints spanning the entire training process, providing valuable insights into the learning dynamics of large language models.* + + +## Dots1Config + +[[autodoc]] Dots1Config + +## Dots1Model + +[[autodoc]] Dots1Model + - forward + +## Dots1ForCausalLM + +[[autodoc]] Dots1ForCausalLM + - forward diff --git a/src/transformers/models/__init__.py b/src/transformers/models/__init__.py index c53fdfc7a38..6d2c5affad9 100644 --- a/src/transformers/models/__init__.py +++ b/src/transformers/models/__init__.py @@ -96,6 +96,7 @@ if TYPE_CHECKING: from .distilbert import * from .dit import * from .donut import * + from .dots1 import * from .dpr import * from .dpt import * from .efficientnet import * diff --git a/src/transformers/models/auto/configuration_auto.py b/src/transformers/models/auto/configuration_auto.py index 3758e237e26..02eb31a503b 100644 --- a/src/transformers/models/auto/configuration_auto.py +++ b/src/transformers/models/auto/configuration_auto.py @@ -112,6 +112,7 @@ CONFIG_MAPPING_NAMES = OrderedDict[str, str]( ("dinov2_with_registers", "Dinov2WithRegistersConfig"), ("distilbert", "DistilBertConfig"), ("donut-swin", "DonutSwinConfig"), + ("dots1", "Dots1Config"), ("dpr", "DPRConfig"), ("dpt", "DPTConfig"), ("efficientformer", "EfficientFormerConfig"), @@ -484,6 +485,7 @@ MODEL_NAMES_MAPPING = OrderedDict[str, str]( ("distilbert", "DistilBERT"), ("dit", "DiT"), ("donut-swin", "DonutSwin"), + ("dots1", "dots1"), ("dpr", "DPR"), ("dpt", "DPT"), ("efficientformer", "EfficientFormer"), diff --git a/src/transformers/models/auto/modeling_auto.py b/src/transformers/models/auto/modeling_auto.py index 935eb8fe8a3..f6cb83d1ee5 100644 --- a/src/transformers/models/auto/modeling_auto.py +++ b/src/transformers/models/auto/modeling_auto.py @@ -105,6 +105,7 @@ MODEL_MAPPING_NAMES = OrderedDict( ("dinov2_with_registers", "Dinov2WithRegistersModel"), ("distilbert", "DistilBertModel"), ("donut-swin", "DonutSwinModel"), + ("dots1", "Dots1Model"), ("dpr", "DPRQuestionEncoder"), ("dpt", "DPTModel"), ("efficientformer", "EfficientFormerModel"), @@ -567,6 +568,7 @@ MODEL_FOR_CAUSAL_LM_MAPPING_NAMES = OrderedDict( ("dbrx", "DbrxForCausalLM"), ("deepseek_v3", "DeepseekV3ForCausalLM"), ("diffllama", "DiffLlamaForCausalLM"), + ("dots1", "Dots1ForCausalLM"), ("electra", "ElectraForCausalLM"), ("emu3", "Emu3ForCausalLM"), ("ernie", "ErnieForCausalLM"), diff --git a/src/transformers/models/dots1/__init__.py b/src/transformers/models/dots1/__init__.py new file mode 100644 index 00000000000..60223e4df87 --- /dev/null +++ b/src/transformers/models/dots1/__init__.py @@ -0,0 +1,27 @@ +# Copyright 2025 The HuggingFace Team.

+ +# Gemma3n + +## Overview + +Gemma3n is a multimodal model with pretrained and instruction-tuned variants, available in E4B and E2B sizes. While +large portions of the language model architecture are shared with prior Gemma releases, there are many new additions in +this model, including [Alternating Updates][altup] (AltUp), [Learned Augmented Residual Layer][laurel] (LAuReL), +[MatFormer][matformer], Per-Layer Embeddings (PLE), activation sparsity, and KV cache sharing. The language model uses +a similar attention pattern to [Gemma 3](./gemma3.md) with alternating 4 local sliding window self-attention layers for +every global self-attention layer with a maximum context length of 32k tokens. Gemma 3n introduces +[MobileNet v5][mobilenetv5] as the vision encoder, using a default resolution of 768x768 pixels, and adds a +[Universal Speech Model][usm] (USM) as the audio encoder. + +The instruction-tuned variant was post-trained with knowledge distillation and reinforcement learning. + +You can find all the original Gemma 3n checkpoints under the [Gemma 3n][gemma3n-collection] release. + +> [!TIP] +> Click on the Gemma 3n models in the right sidebar for more examples of how to apply Gemma to different vision, audio, +> and language tasks. + +The example below demonstrates how to generate text based on an image with [`Pipeline`] or the [`AutoModel`] class. + + + + +```py +import torch +from transformers import pipeline + +pipeline = pipeline( + task="image-text-to-text", + model="google/gemma-3n-e4b", + device=0, + torch_dtype=torch.bfloat16 +) +pipeline( + "https://huggingface.co/datasets/huggingface/documentation-images/resolve/main/pipeline-cat-chonk.jpeg", + text=" What is shown in this image?" +) +``` + + + + +```py +import torch +from transformers import AutoProcessor, Gemma3nForConditionalGeneration + +model = Gemma3nForConditionalGeneration.from_pretrained( + "google/gemma-3n-e4b-it", + torch_dtype=torch.bfloat16, + device_map="auto", + attn_implementation="sdpa" +) +processor = AutoProcessor.from_pretrained( + "google/gemma-3n-e4b-it", + padding_side="left" +) + +messages = [ + { + "role": "system", + "content": [ + {"type": "text", "text": "You are a helpful assistant."} + ] + }, + { + "role": "user", "content": [ + {"type": "image", "url": "https://huggingface.co/datasets/huggingface/documentation-images/resolve/main/pipeline-cat-chonk.jpeg"}, + {"type": "text", "text": "What is shown in this image?"}, + ] + }, +] +inputs = processor.apply_chat_template( + messages, + tokenize=True, + return_dict=True, + return_tensors="pt", + add_generation_prompt=True, +).to("cuda") + +output = model.generate(**inputs, max_new_tokens=50, cache_implementation="static") +print(processor.decode(output[0], skip_special_tokens=True)) +``` + + + + +```bash +echo -e "Plants create energy through a process known as" | transformers run --task text-generation --model google/gemma-3n-e2b --device 0 +``` + + + + +## Notes + +- Use [`Gemma3nForConditionalGeneration`] for image-audio-and-text, image-and-text, image-and-audio, audio-and-text, + image-only and aduio-only inputs. +- Gemma 3n supports multiple images per input, but make sure the images are correctly batched before passing them to + the processor.

As opposed to patch-based neural networks, our -fully-convolutional model operates on full-sized images and jointly computes pixel-level interest point locations and -associated descriptors in one forward pass. We introduce Homographic Adaptation, a multi-scale, multi-homography -approach for boosting interest point detection repeatability and performing cross-domain adaptation (e.g., -synthetic-to-real). Our model, when trained on the MS-COCO generic image dataset using Homographic Adaptation, is able -to repeatedly detect a much richer set of interest points than the initial pre-adapted deep model and any other -traditional corner detector. The final system gives rise to state-of-the-art homography estimation results on HPatches -when compared to LIFT, SIFT and ORB.* +[SuperPoint](https://huggingface.co/papers/1712.07629) is the result of self-supervised training of a fully-convolutional network for interest point detection and description.

It extends the [Pegasus](./pegasus) model with staggered block-local attention, global encoder tokens, and additional pretraining on long text sequences, enabling it to handle inputs of up to 16,000 tokens. PEGASUS-X matches the performance of much larger models while using fewer parameters. -PEGASUS-X (PEGASUS eXtended) extends the PEGASUS models for long input summarization through additional long input pretraining and using staggered block-local attention with global tokens in the encoder. +You can find all the original PEGASUS-X checkpoints under the [Google](https://huggingface.co/google/models?search=pegasus-x) organization. -The abstract from the paper is the following: +> [!TIP] +> This model was contributed by [zphang](https://huggingface.co/zphang). +> +> Click on the PEGASUS-X models in the right sidebar for more examples of how to apply PEGASUS-X to different language tasks. -*While large pretrained Transformer models have proven highly capable at tackling natural language tasks, handling long sequence inputs continues to be a significant challenge. One such task is long input summarization, where inputs are longer than the maximum input context of most pretrained models. Through an extensive set of experiments, we investigate what model architectural changes and pretraining paradigms can most efficiently adapt a pretrained Transformer for long input summarization. We find that a staggered, block-local Transformer with global encoder tokens strikes a good balance of performance and efficiency, and that an additional pretraining phase on long sequences meaningfully improves downstream summarization performance. Based on our findings, we introduce PEGASUS-X, an extension of the PEGASUS model with additional long input pretraining to handle inputs of up to 16K tokens. PEGASUS-X achieves strong performance on long input summarization tasks comparable with much larger models while adding few additional parameters and not requiring model parallelism to train.* +The example below demonstrates how to summarize text with [`Pipeline`], [`AutoModel`], and from the command line. -This model was contributed by [zphang](https://huggingface.co/zphang).

It reduces boilerplate by automatically including standard argument descriptions while also allowing overrides to add new or custom arguments. [Contributing a new model](./modular_transformers) is easier because you don't need to manually add the standard docstrings, and only focus on documenting new arguments. ---- +This guide describes how to use the `@auto_docstring` decorator and how it works. -## 📜 How it Works +## @auto_docstring -The `@auto_docstring` decorator constructs docstrings by: - -1. **Signature Inspection:** It inspects the signature (arguments, types, defaults) of the decorated class's `__init__` method or the decorated function. -2. **Centralized Docstring Fetching:** It retrieves predefined docstrings for common arguments (e.g., `input_ids`, `attention_mask`) from internal library sources (like `ModelArgs` or `ImageProcessorArgs` in `utils/args_doc.py`). -3. **Overriding or Adding Arguments Descriptions:** - * **Direct Docstring Block:** It incorporates custom docstring content from an `r""" """` (or `""" """`) block below the method signature or within the `__init__` docstring. This is for documenting new arguments or overriding standard descriptions. - * **Decorator Arguments (`custom_args`):** A `custom_args` docstring block can be passed to the decorator to provide docstrings for specific arguments directly in the decorator call. This can be used to define the docstring block for new arguments once if they are repeated in multiple places in the modeling file. -4. **Adding Classes and Functions Introduction:** - * **`custom_intro` argument:** Allows prepending a custom introductory paragraph to a class or function docstring. - * **Automatic Introduction Generation:** For model classes with standard naming patterns (like `ModelForCausalLM`) or belonging to a pipeline, the decorator automatically generates an appropriate introductory paragraph using `ClassDocstring` in `utils/args_doc.py` as the source. -5. **Templating:** The decorator uses a templating system, allowing predefined docstrings to include dynamic information deduced from the `auto_modules` of the library, such as `{{processor_class}}` or `{{config_class}}`. -6. **Deducing Relevant Examples:** The decorator attempts to find appropriate usage examples based on the model's task or pipeline compatibility. It extracts checkpoint information from the model's configuration class to provide concrete examples with real model identifiers. -7. **Adding Return Value Documentation:** For methods like `forward`, the decorator can automatically generate the "Returns" section based on the method's return type annotation. For example, for a method returning a `ModelOutput` subclass, it will extracts field descriptions from that class's docstring to create a comprehensive return value description. A custom `Returns` section can also be manually specified in the function docstring block. -8. **Unrolling Kwargs Typed With Unpack Operator:** For specific methods (defined in `UNROLL_KWARGS_METHODS`) or classes (defined in `UNROLL_KWARGS_CLASSES`), the decorator processes `**kwargs` parameters that are typed with `Unpack[KwargsTypedDict]`. It extracts the documentation from the TypedDict and adds each parameter to the function's docstring.

+ +## Overview + +The Encoder-only Mask Transformer (EoMT) model was introduced in the CVPR 2025 Highlight Paper [Your ViT is Secretly an Image Segmentation Model](https://www.tue-mps.org/eomt) by Tommie Kerssies, Niccolò Cavagnero, Alexander Hermans, Narges Norouzi, Giuseppe Averta, Bastian Leibe, Gijs Dubbelman, and Daan de Geus. +EoMT reveals Vision Transformers can perform image segmentation efficiently without task-specific components. + +The abstract from the paper is the following: + +*Vision Transformers (ViTs) have shown remarkable performance and scalability across various computer vision tasks. To apply single-scale ViTs to image segmentation, existing methods adopt a convolutional adapter to generate multi-scale features, a pixel decoder to fuse these features, and a Transformer decoder that uses the fused features to make predictions. In this paper, we show that the inductive biases introduced by these task-specific components can instead be learned by the ViT itself, given sufficiently large models and extensive pre-training. Based on these findings, we introduce the Encoder-only Mask Transformer (EoMT), which repurposes the plain ViT architecture to conduct image segmentation. With large-scale models and pre-training, EoMT obtains a segmentation accuracy similar to state-of-the-art models that use task-specific components. At the same time, EoMT is significantly faster than these methods due to its architectural simplicity, e.g., up to 4x faster with ViT-L. Across a range of model sizes, EoMT demonstrates an optimal balance between segmentation accuracy and prediction speed, suggesting that compute resources are better spent on scaling the ViT itself rather than adding architectural complexity.* + +This model was contributed by [Yaswanth Gali](https://huggingface.co/yaswanthgali). +The original code can be found [here](https://github.com/tue-mps/eomt). + +## Architecture Info + +The `EoMT` model uses a DINOv2-pretrained Vision Transformer with **register tokens** as its backbone. EoMT simplifies the segmentation pipeline by relying solely on the encoder, eliminating the need for task-specific decoders commonly used in prior approaches. + +Architecturally, EoMT introduces a small set of **learned queries** and a lightweight **mask prediction module**. These queries are injected into the final encoder blocks, enabling **joint attention** between image patches and object queries. During training, **masked attention** is applied to constrain each query to focus on its corresponding region—effectively mimicking cross-attention. This constraint is gradually phased out via a **mask annealing strategy**, allowing for **efficient, decoder-free inference** without compromising segmentation performance. + +
+ drawing +
+ + +The model supports semantic, instance, and panoptic segmentation using a unified architecture and task-specific post-processing. + +## Usage Examples + +Use the Hugging Face implementation of EoMT for inference with pre-trained models. + +### Semantic Segmentation + +The EoMT model performs semantic segmentation using sliding-window inference. The input image is resized such that the shorter side matches the target input size, then it is split into overlapping crops. Each crop is then passed through the model. After inference, the predicted logits from each crop are stitched back together and rescaled to the original image size to get the final segmentation mask. + +> **Note:** +> If you want to use a custom target size for **semantic segmentation**, specify it in the following format: +> `{"shortest_edge": 512}` +> Notice that `longest_edge` is not provided here — this is intentional. For semantic segmentation, images are typically **scaled so that the shortest edge is greater than or equal to the target size** hence longest_edge is not necessary. + +```python +import matplotlib.pyplot as plt +import requests +import torch +from PIL import Image + +from transformers import EomtForUniversalSegmentation, AutoImageProcessor + + +model_id = "tue-mps/ade20k_semantic_eomt_large_512" +processor = AutoImageProcessor.from_pretrained(model_id) +model = EomtForUniversalSegmentation.from_pretrained(model_id) + +image = Image.open(requests.get("http://images.cocodataset.org/val2017/000000039769.jpg", stream=True).raw) + +inputs = processor( + images=image, + return_tensors="pt", +) + +# Remove Patch Offsets from inputs — only used later for post-processing. +patch_offsets = inputs.pop("patch_offsets") + +with torch.inference_mode(): + outputs = model(**inputs) + +# Prepare the original image size in the format (height, width) +original_image_sizes = [(image.height, image.width)] + +# Post-process the model outputs to get final segmentation prediction +preds = processor.post_process_semantic_segmentation( + outputs, + patch_offsets=patch_offsets, + original_image_sizes=original_image_sizes, +) + +# Visualize the segmentation mask +plt.imshow(preds[0]) +plt.axis("off") +plt.title("Semantic Segmentation") +plt.show() +``` + +### Instance Segmentation + +The EoMT model performs instance segmentation using padded inference. The input image is resized so that the longer side matches the target input size, and the shorter side is zero-padded to form a square. The resulting mask and class logits are combined through post-processing (adapted from Mask2Former) to produce a unified instance segmentation map, along with segment metadata like segment id, class labels and confidence scores. + +> **Note:** +> To use a custom target size, specify the size as a dictionary in the following format: +> `{"shortest_edge": 512, "longest_edge": 512}` +> For both instance and panoptic segmentation, input images will be **scaled and padded** to this target size. + +```python +import matplotlib.pyplot as plt +import requests +import torch +from PIL import Image + +from transformers import EomtForUniversalSegmentation, AutoImageProcessor + + +model_id = "tue-mps/coco_instance_eomt_large_640" +processor = AutoImageProcessor.from_pretrained(model_id) +model = EomtForUniversalSegmentation.from_pretrained(model_id) + +image = Image.open(requests.get("http://images.cocodataset.org/val2017/000000039769.jpg", stream=True).raw) + +inputs = processor( + images=image, + return_tensors="pt", +) + +with torch.inference_mode(): + outputs = model(**inputs) + +# Prepare the original image size in the format (height, width) +original_image_sizes = [(image.height, image.width)] + +# Post-process the model outputs to get final segmentation prediction +preds = processor.post_process_instance_segmentation( + outputs, + original_image_sizes=original_image_sizes, +) + +# Visualize the segmentation mask +plt.imshow(preds[0]["segmentation"]) +plt.axis("off") +plt.title("Instance Segmentation") +plt.show() +``` + +### Panoptic Segmentation + +The EoMT model performs panoptic segmentation using the same padded inference strategy as in instance segmentation.

-## Overview -The DeBERTa model was proposed in [DeBERTa: Decoding-enhanced BERT with Disentangled Attention](https://huggingface.co/papers/2006.03654) by Pengcheng He, Xiaodong Liu, Jianfeng Gao, Weizhu Chen It is based on Google's -BERT model released in 2018 and Facebook's RoBERTa model released in 2019. +# DeBERTa-v2 -It builds on RoBERTa with disentangled attention and enhanced mask decoder training with half of the data used in -RoBERTa. +[DeBERTa-v2](https://huggingface.co/papers/2006.03654) improves on the original [DeBERTa](./deberta) architecture by using a SentencePiece-based tokenizer and a new vocabulary size of 128K. It also adds an additional convolutional layer within the first transformer layer to better learn local dependencies of input tokens. Finally, the position projection and content projection matrices are shared in the attention layer to reduce the number of parameters. -The abstract from the paper is the following: - -*Recent progress in pre-trained neural language models has significantly improved the performance of many natural -language processing (NLP) tasks. In this paper we propose a new model architecture DeBERTa (Decoding-enhanced BERT with -disentangled attention) that improves the BERT and RoBERTa models using two novel techniques. The first is the -disentangled attention mechanism, where each word is represented using two vectors that encode its content and -position, respectively, and the attention weights among words are computed using disentangled matrices on their -contents and relative positions. Second, an enhanced mask decoder is used to replace the output softmax layer to -predict the masked tokens for model pretraining. We show that these two techniques significantly improve the efficiency -of model pretraining and performance of downstream tasks. Compared to RoBERTa-Large, a DeBERTa model trained on half of -the training data performs consistently better on a wide range of NLP tasks, achieving improvements on MNLI by +0.9% -(90.2% vs. 91.1%), on SQuAD v2.0 by +2.3% (88.4% vs. 90.7%) and RACE by +3.6% (83.2% vs. 86.8%). The DeBERTa code and -pre-trained models will be made publicly available at https://github.com/microsoft/DeBERTa.* +You can find all the original [DeBERTa-v2] checkpoints under the [Microsoft](https://huggingface.co/microsoft?search_models=deberta-v2) organization. -The following information is visible directly on the [original implementation -repository](https://github.com/microsoft/DeBERTa). DeBERTa v2 is the second version of the DeBERTa model. It includes -the 1.5B model used for the SuperGLUE single-model submission and achieving 89.9, versus human baseline 89.8.
