30
+ Summary description and brief definition of inputs and outputs.
31
+
32
+ ### Description
33
+
34
+ Gemma is a family of lightweight, state-of-the-art open models from Google,
35
+ built from the same research and technology used to create the Gemini models.
36
+ Gemma 3 models are multimodal, handling text and image input and generating text
37
+ output, with open weights for both pre-trained variants and instruction-tuned
38
+ variants. Gemma 3 has a large, 128K context window, multilingual support in over
39
+ 140 languages, and is available in more sizes than previous versions. Gemma 3
40
+ models are well-suited for a variety of text generation and image understanding
41
+ tasks, including question answering, summarization, and reasoning. Their
42
+ relatively small size makes it possible to deploy them in environments with
43
+ limited resources such as laptops, desktops or your own cloud infrastructure,
44
+ democratizing access to state of the art AI models and helping foster innovation
45
+ for everyone.
46
+
47
+ ### Inputs and outputs
48
+
49
+ - **Input:**
50
+ - Text string, such as a question, a prompt, or a document to be summarized
51
+ - Images, normalized to 896 x 896 resolution and encoded to 256 tokens
52
+ each
53
+ - Total input context of 128K tokens for the 4B, 12B, and 27B sizes, and
54
+ 32K tokens for the 1B size
55
+
56
+ - **Output:**
57
+ - Generated text in response to the input, such as an answer to a
58
+ question, analysis of image content, or a summary of a document
59
+ - Total output context of 8192 tokens
60
+
61
+ ### Usage
62
+
63
+ Below, there are some code snippets on how to get quickly started with running the model. First, install the Transformers library. Gemma 3 is supported starting from transformers 4.50.0.
64
+
65
+ ```sh
66
+ $ pip install -U transformers
67
+ ```
68
+
69
+ Then, copy the snippet from the section that is relevant for your use case.
70
+
71
+ #### Running with the `pipeline` API
72
+
73
+ With instruction-tuned models, you need to use chat templates to process our inputs first. Then, you can pass it to the pipeline.
74
+
75
+ ```python
76
+ from transformers import pipeline
77
+
78
+ pipe = pipeline("text-generation", model="google/gemma-3-1b-it", device="cuda", torch_dtype=torch.bfloat16)
79
+
80
+ messages = [
81
+ [
82
+ {
83
+ "role": "system",
84
+ "content": [{"type": "text", "text": "You are a helpful assistant."},]
85
+ },
86
+ {
87
+ "role": "user",
88
+ "content": [{"type": "text", "text": "Write a poem on Hugging Face, the company"},]
89
+ },
90
+ ],
91
+ ]
92
+
93
+ output = pipe(messages, max_new_tokens=50)
94
+ ```
95
+
96
+ #### Running the model on a single / multi GPU
97
+
98
+ ```python
99
+ from transformers import AutoTokenizer, BitsAndBytesConfig, Gemma3ForCausalLM
100
+ import torch
101
+
102
+ model_id = "google/gemma-3-1b-it"
103
+
104
+ quantization_config = BitsAndBytesConfig(load_in_8bit=True)
105
+
106
+ model = Gemma3ForCausalLM.from_pretrained(
107
+ model_id, quantization_config=quantization_config
108
+ ).eval()
109
+
110
+ tokenizer = AutoTokenizer.from_pretrained(model_id)
111
+
112
+ messages = [
113
+ [
114
+ {
115
+ "role": "system",
116
+ "content": [{"type": "text", "text": "You are a helpful assistant."},]
117
+ },
118
+ {
119
+ "role": "user",
120
+ "content": [{"type": "text", "text": "Write a poem on Hugging Face, the company"},]
121
+ },
122
+ ],
123
+ ]
124
+ inputs = tokenizer.apply_chat_template(
125
+ messages,
126
+ add_generation_prompt=True,
127
+ tokenize=True,
128
+ return_dict=True,
129
+ return_tensors="pt",
130
+ ).to(model.device).to(torch.bfloat16)
131
+
132
+
133
+ with torch.inference_mode():
134
+ outputs = model.generate(**inputs, max_new_tokens=64)
135
+
136
+ outputs = tokenizer.batch_decode(outputs)
137
+ ```

152
+ ## Model Data
153
+
154
+ Data used for model training and how the data was processed.
155
+
156
+ ### Training Dataset
157
+
158
+ These models were trained on a dataset of text data that includes a wide variety
159
+ of sources. The 27B model was trained with 14 trillion tokens, the 12B model was
160
+ trained with 12 trillion tokens, 4B model was trained with 4 trillion tokens and
161
+ 1B with 2 trillion tokens. Here are the key components:
162
+
163
+ - Web Documents: A diverse collection of web text ensures the model is
164
+ exposed to a broad range of linguistic styles, topics, and vocabulary. The
165
+ training dataset includes content in over 140 languages.
166
+ - Code: Exposing the model to code helps it to learn the syntax and
167
+ patterns of programming languages, which improves its ability to generate
168
+ code and understand code-related questions.
169
+ - Mathematics: Training on mathematical text helps the model learn logical
170
+ reasoning, symbolic representation, and to address mathematical queries.
171
+ - Images: A wide range of images enables the model to perform image
172
+ analysis and visual data extraction tasks.
173
+
174
+ The combination of these diverse data sources is crucial for training a powerful
175
+ multimodal model that can handle a wide variety of different tasks and data
176
+ formats.
177
+
178
+ ### Data Preprocessing
179
+
180
+ Here are the key data cleaning and filtering methods applied to the training
181
+ data:
182
+
183
+ - CSAM Filtering: Rigorous CSAM (Child Sexual Abuse Material) filtering
184
+ was applied at multiple stages in the data preparation process to ensure
185
+ the exclusion of harmful and illegal content.
186
+ - Sensitive Data Filtering: As part of making Gemma pre-trained models
187
+ safe and reliable, automated techniques were used to filter out certain
188
+ personal information and other sensitive data from training sets.
189
+ - Additional methods: Filtering based on content quality and safety in
190
+ line with [our policies][safety-policies].
191
+
192
+ ## Implementation Information
193
+
194
+ Details about the model internals.
195
+
196
+ ### Hardware
197
+
198
+ Gemma was trained using [Tensor Processing Unit (TPU)][tpu] hardware (TPUv4p,
199
+ TPUv5p and TPUv5e). Training vision-language models (VLMS) requires significant
200
+ computational power. TPUs, designed specifically for matrix operations common in
201
+ machine learning, offer several advantages in this domain:
202
+
203
+ - Performance: TPUs are specifically designed to handle the massive
204
+ computations involved in training VLMs. They can speed up training
205
+ considerably compared to CPUs.
206
+ - Memory: TPUs often come with large amounts of high-bandwidth memory,
207
+ allowing for the handling of large models and batch sizes during training.
208
+ This can lead to better model quality.
209
+ - Scalability: TPU Pods (large clusters of TPUs) provide a scalable
210
+ solution for handling the growing complexity of large foundation models.
211
+ You can distribute training across multiple TPU devices for faster and more
212
+ efficient processing.
213
+ - Cost-effectiveness: In many scenarios, TPUs can provide a more
214
+ cost-effective solution for training large models compared to CPU-based
215
+ infrastructure, especially when considering the time and resources saved
216
+ due to faster training.
217
+ - These advantages are aligned with
218
+ [Google's commitments to operate sustainably][sustainability].
219
+
220
+ ### Software
221
+
222
+ Training was done using [JAX][jax] and [ML Pathways][ml-pathways].
223
+
224
+ JAX allows researchers to take advantage of the latest generation of hardware,
225
+ including TPUs, for faster and more efficient training of large models. ML
226
+ Pathways is Google's latest effort to build artificially intelligent systems
227
+ capable of generalizing across multiple tasks. This is specially suitable for
228
+ foundation models, including large language models like these ones.
229
+
230
+ Together, JAX and ML Pathways are used as described in the
231
+ [paper about the Gemini family of models][gemini-2-paper]; *"the 'single
232
+ controller' programming model of Jax and Pathways allows a single Python
233
+ process to orchestrate the entire training run, dramatically simplifying the
234
+ development workflow."*

+ ## Ethics and Safety
350
+
351
+ Ethics and safety evaluation approach and results.
352
+
353
+ ### Evaluation Approach
354
+
355
+ Our evaluation methods include structured evaluations and internal red-teaming
356
+ testing of relevant content policies. Red-teaming was conducted by a number of
357
+ different teams, each with different goals and human evaluation metrics. These
358
+ models were evaluated against a number of different categories relevant to
359
+ ethics and safety, including:
360
+
361
+ - **Child Safety**: Evaluation of text-to-text and image to text prompts
362
+ covering child safety policies, including child sexual abuse and
363
+ exploitation.
364
+ - **Content Safety:** Evaluation of text-to-text and image to text prompts
365
+ covering safety policies including, harassment, violence and gore, and hate
366
+ speech.
367
+ - **Representational Harms**: Evaluation of text-to-text and image to text
368
+ prompts covering safety policies including bias, stereotyping, and harmful
369
+ associations or inaccuracies.
370
+
371
+ In addition to development level evaluations, we conduct "assurance
372
+ evaluations" which are our 'arms-length' internal evaluations for responsibility
373
+ governance decision making. They are conducted separately from the model
374
+ development team, to inform decision making about release. High level findings
375
+ are fed back to the model team, but prompt sets are held-out to prevent
376
+ overfitting and preserve the results' ability to inform decision making.
377
+ Assurance evaluation results are reported to our Responsibility & Safety Council
378
+ as part of release review.
379
+
380
+ ### Evaluation Results
381
+
382
+ For all areas of safety testing, we saw major improvements in the categories of
383
+ child safety, content safety, and representational harms relative to previous
384
+ Gemma models. All testing was conducted without safety filters to evaluate the
385
+ model capabilities and behaviors. For both text-to-text and image-to-text, and
386
+ across all model sizes, the model produced minimal policy violations, and showed
387
+ significant improvements over previous Gemma models' performance with respect
388
+ to ungrounded inferences. A limitation of our evaluations was they included only
389
+ English language prompts.
390
+
391
+ ## Usage and Limitations
392
+
393
+ These models have certain limitations that users should be aware of.
394
+
395
+ ### Intended Usage
396
+
397
+ Open vision-language models (VLMs) models have a wide range of applications
398
+ across various industries and domains. The following list of potential uses is
399
+ not comprehensive. The purpose of this list is to provide contextual information
400
+ about the possible use-cases that the model creators considered as part of model
401
+ training and development.
402
+
403
+ - Content Creation and Communication
404
+ - Text Generation: These models can be used to generate creative text
405
+ formats such as poems, scripts, code, marketing copy, and email drafts.
406
+ - Chatbots and Conversational AI: Power conversational interfaces
407
+ for customer service, virtual assistants, or interactive applications.
408
+ - Text Summarization: Generate concise summaries of a text corpus,
409
+ research papers, or reports.
410
+ - Image Data Extraction: These models can be used to extract,
411
+ interpret, and summarize visual data for text communications.
412
+ - Research and Education
413
+ - Natural Language Processing (NLP) and VLM Research: These
414
+ models can serve as a foundation for researchers to experiment with VLM
415
+ and NLP techniques, develop algorithms, and contribute to the
416
+ advancement of the field.
417
+ - Language Learning Tools: Support interactive language learning
418
+ experiences, aiding in grammar correction or providing writing practice.
419
+ - Knowledge Exploration: Assist researchers in exploring large
420
+ bodies of text by generating summaries or answering questions about
421
+ specific topics.
422
+
423
+ ### Limitations
424
+
425
+ - Training Data
426
+ - The quality and diversity of the training data significantly
427
+ influence the model's capabilities. Biases or gaps in the training data
428
+ can lead to limitations in the model's responses.
429
+ - The scope of the training dataset determines the subject areas
430
+ the model can handle effectively.
431
+ - Context and Task Complexity
432
+ - Models are better at tasks that can be framed with clear
433
+ prompts and instructions. Open-ended or highly complex tasks might be
434
+ challenging.
435
+ - A model's performance can be influenced by the amount of context
436
+ provided (longer context generally leads to better outputs, up to a
437
+ certain point).
438
+ - Language Ambiguity and Nuance
439
+ - Natural language is inherently complex. Models might struggle
440
+ to grasp subtle nuances, sarcasm, or figurative language.
441
+ - Factual Accuracy
442
+ - Models generate responses based on information they learned
443
+ from their training datasets, but they are not knowledge bases. They
444
+ may generate incorrect or outdated factual statements.
445
+ - Common Sense
446
+ - Models rely on statistical patterns in language. They might
447
+ lack the ability to apply common sense reasoning in certain situations.
448
+
449
+ ### Ethical Considerations and Risks
450
+
451
+ The development of vision-language models (VLMs) raises several ethical
452
+ concerns. In creating an open model, we have carefully considered the following:
453
+
454
+ - Bias and Fairness
455
+ - VLMs trained on large-scale, real-world text and image data can
456
+ reflect socio-cultural biases embedded in the training material. These
457
+ models underwent careful scrutiny, input data pre-processing described
458
+ and posterior evaluations reported in this card.
459
+ - Misinformation and Misuse
460
+ - VLMs can be misused to generate text that is false, misleading,
461
+ or harmful.
462
+ - Guidelines are provided for responsible use with the model, see the
463
+ [Responsible Generative AI Toolkit][rai-toolkit].
464
+ - Transparency and Accountability:
465
+ - This model card summarizes details on the models' architecture,
466
+ capabilities, limitations, and evaluation processes.
467
+ - A responsibly developed open model offers the opportunity to
468
+ share innovation by making VLM technology accessible to developers and
469
+ researchers across the AI ecosystem.
470
+
471
+ Risks identified and mitigations:
472
+
473
+ - **Perpetuation of biases**: It's encouraged to perform continuous
474
+ monitoring (using evaluation metrics, human review) and the exploration of
475
+ de-biasing techniques during model training, fine-tuning, and other use
476
+ cases.
477
+ - **Generation of harmful content**: Mechanisms and guidelines for content
478
+ safety are essential. Developers are encouraged to exercise caution and
479
+ implement appropriate content safety safeguards based on their specific
480
+ product policies and application use cases.
481
+ - **Misuse for malicious purposes**: Technical limitations and developer
482
+ and end-user education can help mitigate against malicious applications of
483
+ VLMs. Educational resources and reporting mechanisms for users to flag
484
+ misuse are provided. Prohibited uses of Gemma models are outlined in the
485
+ [Gemma Prohibited Use Policy][prohibited-use].
486
+ - **Privacy violations**: Models were trained on data filtered for removal
487
+ of certain personal information and other sensitive data. Developers are
488
+ encouraged to adhere to privacy regulations with privacy-preserving
489
+ techniques.
490
+
491
+ ### Benefits
492
+
493
+ At the time of release, this family of models provides high-performance open
494
+ vision-language model implementations designed from the ground up for
495
+ responsible AI development compared to similarly sized models.
496
+
497
+ Using the benchmark evaluation metrics described in this document, these models
498
+ have shown to provide superior performance to other, comparably-sized open model
499
+ alternatives.
