46
+ ### Description
47
+
48
+ Gemma is a family of lightweight, state-of-the-art open models from Google,
49
+ built from the same research and technology used to create the Gemini models.
50
+ Gemma 3 models are multimodal, handling text and image input and generating text
51
+ output, with open weights for both pre-trained variants and instruction-tuned
52
+ variants. Gemma 3 has a large, 128K context window, multilingual support in over
53
+ 140 languages, and is available in more sizes than previous versions. Gemma 3
54
+ models are well-suited for a variety of text generation and image understanding
55
+ tasks, including question answering, summarization, and reasoning. Their
56
+ relatively small size makes it possible to deploy them in environments with
57
+ limited resources such as laptops, desktops or your own cloud infrastructure,
58
+ democratizing access to state of the art AI models and helping foster innovation
59
+ for everyone.
60
+
61
+ ### Inputs and outputs
62
+
63
+ - **Input:**
64
+ - Text string, such as a question, a prompt, or a document to be summarized
65

87
+ ## Model Data
88
+
89
+ Data used for model training and how the data was processed.
90
+
91
+ ### Training Dataset
92
+
93
+ These models were trained on a dataset of text data that includes a wide variety
94
+ of sources. The 27B model was trained with 14 trillion tokens, the 12B model was
95
+ trained with 12 trillion tokens, 4B model was trained with 4 trillion tokens and
96
+ 1B with 2 trillion tokens. Here are the key components:
97
+
98
+ - Web Documents: A diverse collection of web text ensures the model is
99
+ exposed to a broad range of linguistic styles, topics, and vocabulary. The
100
+ training dataset includes content in over 140 languages.
101
+ - Code: Exposing the model to code helps it to learn the syntax and
102
+ patterns of programming languages, which improves its ability to generate
103
+ code and understand code-related questions.
104
+ - Mathematics: Training on mathematical text helps the model learn logical
105
+ reasoning, symbolic representation, and to address mathematical queries.
106
+ - Images: A wide range of images enables the model to perform image
107
+ analysis and visual data extraction tasks.
108
+
109
+ The combination of these diverse data sources is crucial for training a powerful
110
+ multimodal model that can handle a wide variety of different tasks and data
111
+ formats.
112
+
113
+ ### Data Preprocessing
114
+
115
+ Here are the key data cleaning and filtering methods applied to the training
116
+ data:
117
+
118
+ - CSAM Filtering: Rigorous CSAM (Child Sexual Abuse Material) filtering
119
+ was applied at multiple stages in the data preparation process to ensure
120
+ the exclusion of harmful and illegal content.
121
+ - Sensitive Data Filtering: As part of making Gemma pre-trained models
122
+ safe and reliable, automated techniques were used to filter out certain
123
+ personal information and other sensitive data from training sets.
124
+ - Additional methods: Filtering based on content quality and safety in
125
+ line with [our policies][safety-policies].
126
+
127
+ ## Implementation Information
128
+
129
+ Details about the model internals.
130
+
131
+ ### Hardware
132
+
133
+ Gemma was trained using [Tensor Processing Unit (TPU)][tpu] hardware (TPUv4p,
134
+ TPUv5p and TPUv5e). Training vision-language models (VLMS) requires significant
135
+ computational power. TPUs, designed specifically for matrix operations common in
136
+ machine learning, offer several advantages in this domain:
137
+
138
+ - Performance: TPUs are specifically designed to handle the massive
139
+ computations involved in training VLMs. They can speed up training
140
+ considerably compared to CPUs.
141
+ - Memory: TPUs often come with large amounts of high-bandwidth memory,
142
+ allowing for the handling of large models and batch sizes during training.
143
+ This can lead to better model quality.
144
+ - Scalability: TPU Pods (large clusters of TPUs) provide a scalable
145
+ solution for handling the growing complexity of large foundation models.
146
+ You can distribute training across multiple TPU devices for faster and more
147
+ efficient processing.
148
+ - Cost-effectiveness: In many scenarios, TPUs can provide a more
149
+ cost-effective solution for training large models compared to CPU-based
150
+ infrastructure, especially when considering the time and resources saved
151
+ due to faster training.
152
+ - These advantages are aligned with
153
+ [Google's commitments to operate sustainably][sustainability].
154
+
155
+ ### Software
156
+
157
+ Training was done using [JAX][jax] and [ML Pathways][ml-pathways].
158
+
159
+ JAX allows researchers to take advantage of the latest generation of hardware,
160
+ including TPUs, for faster and more efficient training of large models. ML
161
+ Pathways is Google's latest effort to build artificially intelligent systems
162
+ capable of generalizing across multiple tasks. This is specially suitable for
163
+ foundation models, including large language models like these ones.
164
+
165
+ Together, JAX and ML Pathways are used as described in the
166
+ [paper about the Gemini family of models][gemini-2-paper]; *"the 'single
167
+ controller' programming model of Jax and Pathways allows a single Python
168
+ process to orchestrate the entire training run, dramatically simplifying the
169
+ development workflow."*

288
+ ## Ethics and Safety
289
+
290
+ Ethics and safety evaluation approach and results.
291
+
292
+ ### Evaluation Approach
293
+
294
+ Our evaluation methods include structured evaluations and internal red-teaming
295
+ testing of relevant content policies. Red-teaming was conducted by a number of
296
+ different teams, each with different goals and human evaluation metrics. These
297
+ models were evaluated against a number of different categories relevant to
298
+ ethics and safety, including:
299
+
300
+ - **Child Safety**: Evaluation of text-to-text and image to text prompts
301
+ covering child safety policies, including child sexual abuse and
302
+ exploitation.
303
+ - **Content Safety:** Evaluation of text-to-text and image to text prompts
304
+ covering safety policies including, harassment, violence and gore, and hate
305
+ speech.
306
+ - **Representational Harms**: Evaluation of text-to-text and image to text
307
+ prompts covering safety policies including bias, stereotyping, and harmful
308
+ associations or inaccuracies.
309
+
310
+ In addition to development level evaluations, we conduct "assurance
311
+ evaluations" which are our 'arms-length' internal evaluations for responsibility
312
+ governance decision making. They are conducted separately from the model
313
+ development team, to inform decision making about release. High level findings
314
+ are fed back to the model team, but prompt sets are held-out to prevent
315
+ overfitting and preserve the results' ability to inform decision making.
316
+ Assurance evaluation results are reported to our Responsibility & Safety Council
317
+ as part of release review.
318

319
+ ### Evaluation Results
320
+
321
+ For all areas of safety testing, we saw major improvements in the categories of
322
+ child safety, content safety, and representational harms relative to previous
323
+ Gemma models. All testing was conducted without safety filters to evaluate the
324
+ model capabilities and behaviors. For both text-to-text and image-to-text, and
325
+ across all model sizes, the model produced minimal policy violations, and showed
326
+ significant improvements over previous Gemma models' performance with respect
327
+ to ungrounded inferences. A limitation of our evaluations was they included only
328
+ English language prompts.
329
+
330
+ ## Usage and Limitations
331
+
332
+ These models have certain limitations that users should be aware of.
333
+
334
+ ### Intended Usage
335
+
336
+ Open vision-language models (VLMs) models have a wide range of applications
337
+ across various industries and domains. The following list of potential uses is
338
+ not comprehensive. The purpose of this list is to provide contextual information
339
+ about the possible use-cases that the model creators considered as part of model
340
+ training and development.
341
+
342
+ - Content Creation and Communication
343
+ - Text Generation: These models can be used to generate creative text
344
+ formats such as poems, scripts, code, marketing copy, and email drafts.
345
+ - Chatbots and Conversational AI: Power conversational interfaces
346
+ for customer service, virtual assistants, or interactive applications.
347
+ - Text Summarization: Generate concise summaries of a text corpus,
348
+ research papers, or reports.
349
+ - Image Data Extraction: These models can be used to extract,
350
+ interpret, and summarize visual data for text communications.
351
+ - Research and Education
352
+ - Natural Language Processing (NLP) and VLM Research: These
353
+ models can serve as a foundation for researchers to experiment with VLM
354
+ and NLP techniques, develop algorithms, and contribute to the
355
+ advancement of the field.
356
+ - Language Learning Tools: Support interactive language learning
357
+ experiences, aiding in grammar correction or providing writing practice.
358
+ - Knowledge Exploration: Assist researchers in exploring large
359
+ bodies of text by generating summaries or answering questions about
360
+ specific topics.
361
+
362
+ ### Limitations
363
+
364
+ - Training Data
365
+ - The quality and diversity of the training data significantly
366
+ influence the model's capabilities. Biases or gaps in the training data
367
+ can lead to limitations in the model's responses.
368
+ - The scope of the training dataset determines the subject areas
369
+ the model can handle effectively.
370
+ - Context and Task Complexity
371
+ - Models are better at tasks that can be framed with clear
372
+ prompts and instructions. Open-ended or highly complex tasks might be
373
+ challenging.
374
+ - A model's performance can be influenced by the amount of context
375
+ provided (longer context generally leads to better outputs, up to a
376
+ certain point).
377
+ - Language Ambiguity and Nuance
378
+ - Natural language is inherently complex. Models might struggle
379
+ to grasp subtle nuances, sarcasm, or figurative language.
380
+ - Factual Accuracy
381
+ - Models generate responses based on information they learned
382
+ from their training datasets, but they are not knowledge bases. They
383
+ may generate incorrect or outdated factual statements.
384
+ - Common Sense
385
+ - Models rely on statistical patterns in language. They might
386
+ lack the ability to apply common sense reasoning in certain situations.
387
+
388
+ ### Ethical Considerations and Risks
389
+
390
+ The development of vision-language models (VLMs) raises several ethical
391
+ concerns. In creating an open model, we have carefully considered the following:
392
+
393
+ - Bias and Fairness
394
+ - VLMs trained on large-scale, real-world text and image data can
395
+ reflect socio-cultural biases embedded in the training material. These
396
+ models underwent careful scrutiny, input data pre-processing described
397
+ and posterior evaluations reported in this card.
398
+ - Misinformation and Misuse
399
+ - VLMs can be misused to generate text that is false, misleading,
400
+ or harmful.
401
+ - Guidelines are provided for responsible use with the model, see the
402
+ [Responsible Generative AI Toolkit][rai-toolkit].
403
+ - Transparency and Accountability:
404
+ - This model card summarizes details on the models' architecture,
405
+ capabilities, limitations, and evaluation processes.
406
+ - A responsibly developed open model offers the opportunity to
407
+ share innovation by making VLM technology accessible to developers and
408
+ researchers across the AI ecosystem.
409
+
410
+ Risks identified and mitigations:
411
+
412
+ - **Perpetuation of biases**: It's encouraged to perform continuous
413
+ monitoring (using evaluation metrics, human review) and the exploration of
414
+ de-biasing techniques during model training, fine-tuning, and other use
415
+ cases.
416
+ - **Generation of harmful content**: Mechanisms and guidelines for content
417
+ safety are essential. Developers are encouraged to exercise caution and
418
+ implement appropriate content safety safeguards based on their specific
419
+ product policies and application use cases.
420
+ - **Misuse for malicious purposes**: Technical limitations and developer
421
+ and end-user education can help mitigate against malicious applications of
422
+ VLMs. Educational resources and reporting mechanisms for users to flag
423
+ misuse are provided. Prohibited uses of Gemma models are outlined in the
424
+ [Gemma Prohibited Use Policy][prohibited-use].
425
+ - **Privacy violations**: Models were trained on data filtered for removal
426
+ of certain personal information and other sensitive data. Developers are
427
+ encouraged to adhere to privacy regulations with privacy-preserving
428
+ techniques.
429
+
430
+ ### Benefits
431
+
432
+ At the time of release, this family of models provides high-performance open
433
+ vision-language model implementations designed from the ground up for
434
+ responsible AI development compared to similarly sized models.
435
+
436
+ Using the benchmark evaluation metrics described in this document, these models
437
+ have shown to provide superior performance to other, comparably-sized open model
438
+ alternatives.
