33
 
34
+ Summary description and brief definition of inputs and outputs.
35
 
36
+ ### Description
37
 
38
+ Gemma is a family of lightweight, state-of-the-art open models from Google,
39
+ built from the same research and technology used to create the Gemini models.
40
+ They are text-to-text, decoder-only large language models, available in English,
41
+ with open weights, pre-trained variants, and instruction-tuned variants. Gemma
42
+ models are well-suited for a variety of text generation tasks, including
43
+ question answering, summarization, and reasoning. Their relatively small size
44
+ makes it possible to deploy them in environments with limited resources such as
45
+ a laptop, desktop or your own cloud infrastructure, democratizing access to
46
+ state of the art AI models and helping foster innovation for everyone.
47
 
48
+ ### Usage
49
 
50
+ Below we share some code snippets on how to get quickly started with running the model. First make sure to `pip install -U transformers`, then copy the snippet from the section that is relevant for your usecase.
51
 
 
52
 
53
+ #### Fine-tuning the model
54
 
55
+ You can find fine-tuning scripts and notebook under the [`examples/` directory](https://huggingface.co/google/gemma-7b/tree/main/examples) of [`google/gemma-7b`](https://huggingface.co/google/gemma-7b) repository. To adapt it to this model, simply change the model-id to `google/gemma-2b`.
56
+ In that repository, we provide:
57
 
58
+ * A script to perform Supervised Fine-Tuning (SFT) on UltraChat dataset using QLoRA
59
+ * A script to perform SFT using FSDP on TPU devices
60
+ * A notebook that you can run on a free-tier Google Colab instance to perform SFT on English quotes dataset
61
 
 
62
 
 
63
 
64
+ #### Running the model on a CPU
65
 
 
66
 
67

69
 
70
+ tokenizer = AutoTokenizer.from_pretrained("google/gemma-2b")
71
+ model = AutoModelForCausalLM.from_pretrained("google/gemma-2b")
72
 
73
+ input_text = "Write me a poem about Machine Learning."
74
+ input_ids = tokenizer(input_text, return_tensors="pt")
75
 
76
+ outputs = model.generate(**input_ids)
77
+ print(tokenizer.decode(outputs[0]))
78
+ ```
79
 
 
80
 
81
+ #### Running the model on a single / multi GPU
82
 
 
83
 
84
+ ```python
85
+ # pip install accelerate
86
+ from transformers import AutoTokenizer, AutoModelForCausalLM
87
 
88
+ tokenizer = AutoTokenizer.from_pretrained("google/gemma-2b")
89
+ model = AutoModelForCausalLM.from_pretrained("google/gemma-2b", device_map="auto")
90
 
91
+ input_text = "Write me a poem about Machine Learning."
92
+ input_ids = tokenizer(input_text, return_tensors="pt").to("cuda")
93
 
94
+ outputs = model.generate(**input_ids)
95
+ print(tokenizer.decode(outputs[0]))
96
+ ```
97
 
98
 
99
+ #### Running the model on a GPU using different precisions
100
 
101
+ * _Using `torch.float16`_
102
 
103
+ ```python
104
+ # pip install accelerate
105
+ from transformers import AutoTokenizer, AutoModelForCausalLM
106
 
107
+ tokenizer = AutoTokenizer.from_pretrained("google/gemma-2b")
108
+ model = AutoModelForCausalLM.from_pretrained("google/gemma-2b", device_map="auto", torch_dtype=torch.float16)
109
 
110
+ input_text = "Write me a poem about Machine Learning."
111
+ input_ids = tokenizer(input_text, return_tensors="pt").to("cuda")
112
 
113
+ outputs = model.generate(**input_ids)
114
+ print(tokenizer.decode(outputs[0]))
115
+ ```
116
 
117
+ * _Using `torch.bfloat16`_
118
 
119
+ ```python
120
+ # pip install accelerate
121
+ from transformers import AutoTokenizer, AutoModelForCausalLM
122
 
123
+ tokenizer = AutoTokenizer.from_pretrained("google/gemma-2b")
124
+ model = AutoModelForCausalLM.from_pretrained("google/gemma-2b", device_map="auto", torch_dtype=torch.bfloat16)
125
 
126
+ input_text = "Write me a poem about Machine Learning."
127
+ input_ids = tokenizer(input_text, return_tensors="pt").to("cuda")
128
 
129
+ outputs = model.generate(**input_ids)
130
+ print(tokenizer.decode(outputs[0]))
131
+ ```
132
 
133
+ #### Quantized Versions through `bitsandbytes`
134
 
135
+ * _Using 8-bit precision (int8)_
136
 
137
+ ```python
138
+ # pip install bitsandbytes accelerate
139
+ from transformers import AutoTokenizer, AutoModelForCausalLM, BitsAndBytesConfig
140
 
141
+ quantization_config = BitsAndBytesConfig(load_in_8bit=True)
142
 
143
+ tokenizer = AutoTokenizer.from_pretrained("google/gemma-2b")
144
+ model = AutoModelForCausalLM.from_pretrained("google/gemma-2b", quantization_config=quantization_config)
145
 
146
+ input_text = "Write me a poem about Machine Learning."
147
+ input_ids = tokenizer(input_text, return_tensors="pt").to("cuda")
148
 
149
+ outputs = model.generate(**input_ids)
150
+ print(tokenizer.decode(outputs[0]))
151
+ ```
152
 
153
+ * _Using 4-bit precision_
154
 
155
+ ```python
156
+ # pip install bitsandbytes accelerate
157
+ from transformers import AutoTokenizer, AutoModelForCausalLM, BitsAndBytesConfig
158
 
159
+ quantization_config = BitsAndBytesConfig(load_in_4bit=True)
160
 
161
+ tokenizer = AutoTokenizer.from_pretrained("google/gemma-2b")
162
+ model = AutoModelForCausalLM.from_pretrained("google/gemma-2b", quantization_config=quantization_config)
163
 
164
+ input_text = "Write me a poem about Machine Learning."
165
+ input_ids = tokenizer(input_text, return_tensors="pt").to("cuda")
166
 
167
+ outputs = model.generate(**input_ids)
168
+ print(tokenizer.decode(outputs[0]))
169
+ ```
170
 
 
171
 
172
+ #### Other optimizations
173
 
174
+ * _Flash Attention 2_
175
 
176
+ First make sure to install `flash-attn` in your environment `pip install flash-attn`
177
 
178
+ ```diff
179
+ model = AutoModelForCausalLM.from_pretrained(
180
+ model_id,
181
+ torch_dtype=torch.float16,
182
+ + attn_implementation="flash_attention_2"
183
+ ).to(0)
184
+ ```
185
 
186
+ ### Inputs and outputs
187
 
188
+ * **Input:** Text string, such as a question, a prompt, or a document to be
189
+ summarized.
190
+ * **Output:** Generated English-language text in response to the input, such
191
+ as an answer to a question, or a summary of a document.
192
 
193
+ ## Model Data
194
 
195
+ Data used for model training and how the data was processed.
196
 
197
+ ### Training Dataset
198
 
199
+ These models were trained on a dataset of text data that includes a wide variety
200
+ of sources, totaling 6 trillion tokens. Here are the key components:
201
 
202
+ * Web Documents: A diverse collection of web text ensures the model is exposed
203
+ to a broad range of linguistic styles, topics, and vocabulary. Primarily
204
+ English-language content.
205
+ * Code: Exposing the model to code helps it to learn the syntax and patterns of
206
+ programming languages, which improves its ability to generate code or
207
+ understand code-related questions.
208
+ * Mathematics: Training on mathematical text helps the model learn logical
209
+ reasoning, symbolic representation, and to address mathematical queries.
210
 
211
+ The combination of these diverse data sources is crucial for training a powerful
212
+ language model that can handle a wide variety of different tasks and text
213
+ formats.
214
 
215
+ ### Data Preprocessing
216
 
217
+ Here are the key data cleaning and filtering methods applied to the training
218
+ data:
219
 
220
+ * CSAM Filtering: Rigorous CSAM (Child Sexual Abuse Material) filtering was
221
+ applied at multiple stages in the data preparation process to ensure the
222
+ exclusion of harmful and illegal content
223
+ * Sensitive Data Filtering: As part of making Gemma pre-trained models safe and
224
+ reliable, automated techniques were used to filter out certain personal
225
+ information and other sensitive data from training sets.
226
+ * Additional methods: Filtering based on content quality and safely in line with
227
+ [our policies](https://storage.googleapis.com/gweb-uniblog-publish-prod/documents/2023_Google_AI_Principles_Progress_Update.pdf#page=11).
228
 
229
+ ## Implementation Information
230
 
231
+ Details about the model internals.
232
 
233
+ ### Hardware
234
 
235
+ Gemma was trained using the latest generation of
236
+ [Tensor Processing Unit (TPU)](https://cloud.google.com/tpu/docs/intro-to-tpu) hardware (TPUv5e).
237
 
238
+ Training large language models requires significant computational power. TPUs,
239
+ designed specifically for matrix operations common in machine learning, offer
240
+ several advantages in this domain:
241
 
242
+ * Performance: TPUs are specifically designed to handle the massive computations
243
+ involved in training LLMs. They can speed up training considerably compared to
244
+ CPUs.
245
+ * Memory: TPUs often come with large amounts of high-bandwidth memory, allowing
246
+ for the handling of large models and batch sizes during training. This can
247
+ lead to better model quality.
248
+ * Scalability: TPU Pods (large clusters of TPUs) provide a scalable solution for
249
+ handling the growing complexity of large foundation models. You can distribute
250
+ training across multiple TPU devices for faster and more efficient processing.
251
+ * Cost-effectiveness: In many scenarios, TPUs can provide a more cost-effective
252
+ solution for training large models compared to CPU-based infrastructure,
253
+ especially when considering the time and resources saved due to faster
254
+ training.
255
+ * These advantages are aligned with
256
+ [Google's commitments to operate sustainably](https://sustainability.google/operating-sustainably/).
257
 
258
+ ### Software
259
 
260
+ Training was done using [JAX](https://github.com/google/jax) and [ML Pathways](https://blog.google/technology/ai/introducing-pathways-next-generation-ai-architecture/ml-pathways).
261
 
262
+ JAX allows researchers to take advantage of the latest generation of hardware,
263
+ including TPUs, for faster and more efficient training of large models.
264
 
265
+ ML Pathways is Google's latest effort to build artificially intelligent systems
266
+ capable of generalizing across multiple tasks. This is specially suitable for
267
+ [foundation models](https://ai.google/discover/foundation-models/), including large language models like
268
+ these ones.
269
 
270
+ Together, JAX and ML Pathways are used as described in the
271
+ [paper about the Gemini family of models](https://arxiv.org/abs/2312.11805); "the 'single
272
+ controller' programming model of Jax and Pathways allows a single Python
273
+ process to orchestrate the entire training run, dramatically simplifying the
274
+ development workflow."

+ Ethics and safety evaluation approach and results.
311
+
312
+ ### Evaluation Approach
313
+
314
+ Our evaluation methods include structured evaluations and internal red-teaming
315
+ testing of relevant content policies. Red-teaming was conducted by a number of
316
+ different teams, each with different goals and human evaluation metrics. These
317
+ models were evaluated against a number of different categories relevant to
318
+ ethics and safety, including:
319
+
320
+ * Text-to-Text Content Safety: Human evaluation on prompts covering safety
321
+ policies including child sexual abuse and exploitation, harassment, violence
322
+ and gore, and hate speech.
323
+ * Text-to-Text Representational Harms: Benchmark against relevant academic
324
+ datasets such as [WinoBias](https://arxiv.org/abs/1804.06876) and [BBQ Dataset](https://arxiv.org/abs/2110.08193v2).
325
+ * Memorization: Automated evaluation of memorization of training data, including
326
+ the risk of personally identifiable information exposure.
327
+ * Large-scale harm: Tests for "dangerous capabilities," such as chemical,
328
+ biological, radiological, and nuclear (CBRN) risks.
329
+
330
+ ### Evaluation Results
331
+
332
+ The results of ethics and safety evaluations are within acceptable thresholds
333
+ for meeting [internal policies](https://storage.googleapis.com/gweb-uniblog-publish-prod/documents/2023_Google_AI_Principles_Progress_Update.pdf#page=11) for categories such as child
334
+ safety, content safety, representational harms, memorization, large-scale harms.
335
+ On top of robust internal evaluations, the results of well known safety
336
+ benchmarks like BBQ, BOLD, Winogender, Winobias, RealToxicity, and TruthfulQA
337
+ are shown here.

354
+ ## Usage and Limitations
355
+
356
+ These models have certain limitations that users should be aware of.
357
+
358
+ ### Intended Usage
359
+
360
+ Open Large Language Models (LLMs) have a wide range of applications across
361
+ various industries and domains. The following list of potential uses is not
362
+ comprehensive. The purpose of this list is to provide contextual information
363
+ about the possible use-cases that the model creators considered as part of model
364
+ training and development.
365
+
366
+ * Content Creation and Communication
367
+ * Text Generation: These models can be used to generate creative text formats
368
+ such as poems, scripts, code, marketing copy, and email drafts.
369
+ * Chatbots and Conversational AI: Power conversational interfaces for customer
370
+ service, virtual assistants, or interactive applications.
371
+ * Text Summarization: Generate concise summaries of a text corpus, research
372
+ papers, or reports.
373
+ * Research and Education
374
+ * Natural Language Processing (NLP) Research: These models can serve as a
375
+ foundation for researchers to experiment with NLP techniques, develop
376
+ algorithms, and contribute to the advancement of the field.
377
+ * Language Learning Tools: Support interactive language learning experiences,
378
+ aiding in grammar correction or providing writing practice.
379
+ * Knowledge Exploration: Assist researchers in exploring large bodies of text
380
+ by generating summaries or answering questions about specific topics.
381
+
382
+ ### Limitations
383
+
384
+ * Training Data
385
+ * The quality and diversity of the training data significantly influence the
386
+ model's capabilities. Biases or gaps in the training data can lead to
387
+ limitations in the model's responses.
388
+ * The scope of the training dataset determines the subject areas the model can
389
+ handle effectively.
390
+ * Context and Task Complexity
391
+ * LLMs are better at tasks that can be framed with clear prompts and
392
+ instructions. Open-ended or highly complex tasks might be challenging.
393
+ * A model's performance can be influenced by the amount of context provided
394
+ (longer context generally leads to better outputs, up to a certain point).
395
+ * Language Ambiguity and Nuance
396
+ * Natural language is inherently complex. LLMs might struggle to grasp subtle
397
+ nuances, sarcasm, or figurative language.
398
+ * Factual Accuracy
399
+ * LLMs generate responses based on information they learned from their
400
+ training datasets, but they are not knowledge bases. They may generate
401
+ incorrect or outdated factual statements.
402
+ * Common Sense
403
+ * LLMs rely on statistical patterns in language. They might lack the ability
404
+ to apply common sense reasoning in certain situations.
405
+
406
+ ### Ethical Considerations and Risks
407
+
408
+ The development of large language models (LLMs) raises several ethical concerns.
409
+ In creating an open model, we have carefully considered the following:
410
+
411
+ * Bias and Fairness
412
+ * LLMs trained on large-scale, real-world text data can reflect socio-cultural
413
+ biases embedded in the training material. These models underwent careful
414
+ scrutiny, input data pre-processing described and posterior evaluations
415
+ reported in this card.
416
+ * Misinformation and Misuse
417
+ * LLMs can be misused to generate text that is false, misleading, or harmful.
418
+ * Guidelines are provided for responsible use with the model, see the
419
+ [Responsible Generative AI Toolkit](http://ai.google.dev/gemma/responsible).
420
+ * Transparency and Accountability:
421
+ * This model card summarizes details on the models' architecture,
422
+ capabilities, limitations, and evaluation processes.
423
+ * A responsibly developed open model offers the opportunity to share
424
+ innovation by making LLM technology accessible to developers and researchers
425
+ across the AI ecosystem.
426
+
427
+ Risks identified and mitigations:
428
+
429
+ * Perpetuation of biases: It's encouraged to perform continuous monitoring
430
+ (using evaluation metrics, human review) and the exploration of de-biasing
431
+ techniques during model training, fine-tuning, and other use cases.
432
+ * Generation of harmful content: Mechanisms and guidelines for content safety
433
+ are essential. Developers are encouraged to exercise caution and implement
434
+ appropriate content safety safeguards based on their specific product policies
435
+ and application use cases.
436
+ * Misuse for malicious purposes: Technical limitations and developer and
437
+ end-user education can help mitigate against malicious applications of LLMs.
438
+ Educational resources and reporting mechanisms for users to flag misuse are
439
+ provided. Prohibited uses of Gemma models are outlined in the
440
+ [Gemma Prohibited Use Policy](https://ai.google.dev/gemma/prohibited_use_policy).
441
+ * Privacy violations: Models were trained on data filtered for removal of PII
442
+ (Personally Identifiable Information). Developers are encouraged to adhere to
443
+ privacy regulations with privacy-preserving techniques.
444
+
445
+ ### Benefits
446
+
447
+ At the time of release, this family of models provides high-performance open
448
+ large language model implementations designed from the ground up for Responsible
449
+ AI development compared to similarly sized models.
450
+
451
+ Using the benchmark evaluation metrics described in this document, these models
452
+ have shown to provide superior performance to other, comparably-sized open model
453
+ alternatives.
