52
+ ### Description
53
+
54
+ Gemma is a family of lightweight, state-of-the-art open models from Google,
55
+ built from the same research and technology used to create the Gemini models.
56
+ They are text-to-text, decoder-only large language models, available in English,
57
+ with open weights for both pre-trained variants and instruction-tuned variants.
58
+ Gemma models are well-suited for a variety of text generation tasks, including
59
+ question answering, summarization, and reasoning. Their relatively small size
60
+ makes it possible to deploy them in environments with limited resources such as
61
+ a laptop, desktop or your own cloud infrastructure, democratizing access to
62
+ state of the art AI models and helping foster innovation for everyone.
63
+
64
+ ### Usage
65
+
66
+ Below we share some code snippets on how to get quickly started with running the model. First, install the Transformers library with:
67
+ ```sh
68
+ pip install -U transformers
69
+ ```
70
+
71
+ Then, copy the snippet from the section that is relevant for your usecase.
72
+
73
+ #### Running with the `pipeline` API
74
+
75
+ ```python
76
+ import torch
77
+ from transformers import pipeline
78
+
79
+ pipe = pipeline(
80
+ "text-generation",
81
+ model="google/gemma-2-2b-it",
82
+ model_kwargs={"torch_dtype": torch.bfloat16},
83
+ device="cuda", # replace with "mps" to run on a Mac device
84
+ )
85
+
86
+ messages = [
87
+ {"role": "user", "content": "Who are you? Please, answer in pirate-speak."},
88
+ ]
89
+
90
+ outputs = pipe(messages, max_new_tokens=256)
91
+ assistant_response = outputs[0]["generated_text"][-1]["content"].strip()
92
+ print(assistant_response)
93
+ # Ahoy, matey! I be Gemma, a digital scallywag, a language-slingin' parrot of the digital seas. I be here to help ye with yer wordy woes, answer yer questions, and spin ye yarns of the digital world. So, what be yer pleasure, eh? 🦜
94
+ ```
95
+
96
+ #### Running the model on a single / multi GPU
97
+
98
+ ```python
99
+ # pip install accelerate
100
+ from transformers import AutoTokenizer, AutoModelForCausalLM
101
+ import torch
102
+
103
+ tokenizer = AutoTokenizer.from_pretrained("google/gemma-2-2b-it")
104
+ model = AutoModelForCausalLM.from_pretrained(
105
+ "google/gemma-2-2b-it",
106
+ device_map="auto",
107
+ torch_dtype=torch.bfloat16,
108
+ )
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, max_new_tokens=32)
114
+ print(tokenizer.decode(outputs[0]))
115
+ ```
116
+
117
+ You can ensure the correct chat template is applied by using `tokenizer.apply_chat_template` as follows:
118
+ ```python
119
+ messages = [
120
+ {"role": "user", "content": "Write me a poem about Machine Learning."},
121
+ ]
122
+ input_ids = tokenizer.apply_chat_template(messages, return_tensors="pt", return_dict=True).to("cuda")
123
+
124
+ outputs = model.generate(**input_ids, max_new_tokens=256)
125
+ print(tokenizer.decode(outputs[0]))
126
+ ```
127
+
128
+ <a name="precisions"></a>
129
+ #### Running the model on a GPU using different precisions
130
+
131
+ The native weights of this model were exported in `bfloat16` precision.
132
+
133
+ You can also use `float32` if you skip the dtype, but no precision increase will occur (model weights will just be upcasted to `float32`). See examples below.
134
+
135
+ * _Upcasting to `torch.float32`_
136
+
137
+ ```python
138
+ # pip install accelerate
139
+ from transformers import AutoTokenizer, AutoModelForCausalLM
140
+
141
+ tokenizer = AutoTokenizer.from_pretrained("google/gemma-2-2b-it")
142
+ model = AutoModelForCausalLM.from_pretrained(
143
+ "google/gemma-2-2b-it",
144
+ device_map="auto",
145
+ )
146
+
147
+ input_text = "Write me a poem about Machine Learning."
148
+ input_ids = tokenizer(input_text, return_tensors="pt").to("cuda")
149
+
150
+ outputs = model.generate(**input_ids, max_new_tokens=32)
151
+ print(tokenizer.decode(outputs[0]))
152
+ ```
153
+
154
+ #### Running the model through a CLI
155
+
156
+ The [local-gemma](https://github.com/huggingface/local-gemma) repository contains a lightweight wrapper around Transformers
157
+ for running Gemma 2 through a command line interface, or CLI. Follow the [installation instructions](https://github.com/huggingface/local-gemma#cli-usage)
158
+ for getting started, then launch the CLI through the following command:
159

+ Torch compile
221

222
+
223
+ [Torch compile](https://pytorch.org/tutorials/intermediate/torch_compile_tutorial.html) is a method for speeding-up the
224
+ inference of PyTorch modules. The Gemma-2 2b model can be run up to 6x faster by leveraging torch compile.
225
+
226
+ Note that two warm-up steps are required before the full inference speed is realised:
227
+
228
+ ```python
229
+ import os
230
+ os.environ["TOKENIZERS_PARALLELISM"] = "false"
231
+
232
+ from transformers import AutoTokenizer, Gemma2ForCausalLM
233
+ from transformers.cache_utils import HybridCache
234

235

+ torch.set_float32_matmul_precision("high")
237

241

242
+
243
+ # apply the torch compile transformation
244
+ model.forward = torch.compile(model.forward, mode="reduce-overhead", fullgraph=True)
245
+
246
+ # pre-process inputs
247
+ input_text = "The theory of special relativity states "
248
+ model_inputs = tokenizer(input_text, return_tensors="pt").to("cuda")
249
+ prompt_length = model_inputs.input_ids.shape[1]
250
+
251
+ # set-up k/v cache
252
+ past_key_values = HybridCache(

+ max_batch_size=1,
255
+ max_cache_len=model.config.max_position_embeddings,
256
+ device=model.device,
257
+ dtype=model.dtype
258
+ )
259
+
260
+ # enable passing kv cache to generate
261
+ model._supports_cache_class = True
262
+ model.generation_config.cache_implementation = None
263
+
264
+ # two warm-up steps
265
+ for idx in range(2):
266
+ outputs = model.generate(**model_inputs, past_key_values=past_key_values, do_sample=True, temperature=1.0, max_new_tokens=128)
267
+ past_key_values.reset()
268
+
269
+ # fast run
270
+ outputs = model.generate(**model_inputs, past_key_values=past_key_values, do_sample=True, temperature=1.0, max_new_tokens=128)
271
+ print(tokenizer.decode(outputs[0], skip_special_tokens=True))
272
+ ```

+ ### Chat Template
279
+
280
+ The instruction-tuned models use a chat template that must be adhered to for conversational use.
281
+ The easiest way to apply it is using the tokenizer's built-in chat template, as shown in the following snippet.
282
+
283
+ Let's load the model and apply the chat template to a conversation. In this example, we'll start with a single user interaction:
284
+
285
+ ```py
286
+ from transformers import AutoTokenizer, AutoModelForCausalLM
287
+ import transformers
288
+ import torch
289
+
290
+ model_id = "google/gemma-2-2b-it"
291
+ dtype = torch.bfloat16
292
+
293
+ tokenizer = AutoTokenizer.from_pretrained(model_id)
294
+ model = AutoModelForCausalLM.from_pretrained(
295
+ model_id,
296
+ device_map="cuda",
297
+ torch_dtype=dtype,)
298
+
299
+ chat = [
300
+ { "role": "user", "content": "Write a hello world program" },
301
+ ]
302
+ prompt = tokenizer.apply_chat_template(chat, tokenize=False, add_generation_prompt=True)
303
+ ```
304
+
305
+ At this point, the prompt contains the following text:
306
+
307
+ ```
308
+ <bos><start_of_turn>user
309
+ Write a hello world program<end_of_turn>
310
+ <start_of_turn>model
311
+ ```
312
+
313
+ As you can see, each turn is preceded by a `<start_of_turn>` delimiter and then the role of the entity
314
+ (either `user`, for content supplied by the user, or `model` for LLM responses). Turns finish with
315
+ the `<end_of_turn>` token.
316
+
317
+ You can follow this format to build the prompt manually, if you need to do it without the tokenizer's
318
+ chat template.
319
+
320
+ After the prompt is ready, generation can be performed like this:
321
+
322
+ ```py
323
+ inputs = tokenizer.encode(prompt, add_special_tokens=False, return_tensors="pt")
324
+ outputs = model.generate(input_ids=inputs.to(model.device), max_new_tokens=150)
325
+ print(tokenizer.decode(outputs[0]))
326
+ ```
327
+
328
+ ### Inputs and outputs
329
+
330
+ * **Input:** Text string, such as a question, a prompt, or a document to be
331
+ summarized.
332
+ * **Output:** Generated English-language text in response to the input, such
333
+ as an answer to a question, or a summary of a document.

+ ## Model Data
349
+
350
+ Data used for model training and how the data was processed.
351
+
352
+ ### Training Dataset
353
+
354
+ These models were trained on a dataset of text data that includes a wide variety
355
+ of sources. The 27B model was trained with 13 trillion tokens, the 9B model was
356
+ trained with 8 trillion tokens, and 2B model was trained with 2 trillion tokens.
357
+ Here are the key components:
358
+
359
+ * Web Documents: A diverse collection of web text ensures the model is exposed
360
+ to a broad range of linguistic styles, topics, and vocabulary. Primarily
361
+ English-language content.
362
+ * Code: Exposing the model to code helps it to learn the syntax and patterns of
363
+ programming languages, which improves its ability to generate code or
364
+ understand code-related questions.
365
+ * Mathematics: Training on mathematical text helps the model learn logical
366
+ reasoning, symbolic representation, and to address mathematical queries.
367
+
368
+ The combination of these diverse data sources is crucial for training a powerful
369
+ language model that can handle a wide variety of different tasks and text
370
+ formats.
371
+
372
+ ### Data Preprocessing
373
+
374
+ Here are the key data cleaning and filtering methods applied to the training
375
+ data:
376
+
377
+ * CSAM Filtering: Rigorous CSAM (Child Sexual Abuse Material) filtering was
378
+ applied at multiple stages in the data preparation process to ensure the
379
+ exclusion of harmful and illegal content.
380
+ * Sensitive Data Filtering: As part of making Gemma pre-trained models safe and
381
+ reliable, automated techniques were used to filter out certain personal
382
+ information and other sensitive data from training sets.
383
+ * Additional methods: Filtering based on content quality and safety in line with
384
+ [our policies][safety-policies].
385
+
386
+ ## Implementation Information
387
+
388
+ Details about the model internals.
389
+
390
+ ### Hardware
391
+
392
+ Gemma was trained using the latest generation of
393
+ [Tensor Processing Unit (TPU)][tpu] hardware (TPUv5p).
394
+
395
+ Training large language models requires significant computational power. TPUs,
396
+ designed specifically for matrix operations common in machine learning, offer
397
+ several advantages in this domain:
398
+
399
+ * Performance: TPUs are specifically designed to handle the massive computations
400
+ involved in training LLMs. They can speed up training considerably compared to
401
+ CPUs.
402
+ * Memory: TPUs often come with large amounts of high-bandwidth memory, allowing
403
+ for the handling of large models and batch sizes during training. This can
404
+ lead to better model quality.
405
+ * Scalability: TPU Pods (large clusters of TPUs) provide a scalable solution for
406
+ handling the growing complexity of large foundation models. You can distribute
407
+ training across multiple TPU devices for faster and more efficient processing.
408
+ * Cost-effectiveness: In many scenarios, TPUs can provide a more cost-effective
409
+ solution for training large models compared to CPU-based infrastructure,
410
+ especially when considering the time and resources saved due to faster
411
+ training.
412
+ * These advantages are aligned with
413
+ [Google's commitments to operate sustainably][sustainability].
414
+
415
+ ### Software
416
+
417
+ Training was done using [JAX][jax] and [ML Pathways][ml-pathways].
418
+
419
+ JAX allows researchers to take advantage of the latest generation of hardware,
420
+ including TPUs, for faster and more efficient training of large models.
421
+
422
+ ML Pathways is Google's latest effort to build artificially intelligent systems
423
+ capable of generalizing across multiple tasks. This is specially suitable for
424
+ [foundation models][foundation-models], including large language models like
425
+ these ones.
426
+
427
+ Together, JAX and ML Pathways are used as described in the
428
+ [paper about the Gemini family of models][gemini-2-paper]; "the 'single
429
+ controller' programming model of Jax and Pathways allows a single Python
430
+ process to orchestrate the entire training run, dramatically simplifying the
431
+ development workflow."

+
464
+ Ethics and safety evaluation approach and results.
465
+
466
+ ### Evaluation Approach
467
+
468
+ Our evaluation methods include structured evaluations and internal red-teaming
469
+ testing of relevant content policies. Red-teaming was conducted by a number of
470
+ different teams, each with different goals and human evaluation metrics. These
471
+ models were evaluated against a number of different categories relevant to
472
+ ethics and safety, including:
473
+
474
+ * Text-to-Text Content Safety: Human evaluation on prompts covering safety
475
+ policies including child sexual abuse and exploitation, harassment, violence
476
+ and gore, and hate speech.
477
+ * Text-to-Text Representational Harms: Benchmark against relevant academic
478
+ datasets such as [WinoBias][winobias] and [BBQ Dataset][bbq].
479
+ * Memorization: Automated evaluation of memorization of training data, including
480
+ the risk of personally identifiable information exposure.
481
+ * Large-scale harm: Tests for "dangerous capabilities," such as chemical,
482
+ biological, radiological, and nuclear (CBRN) risks.
483
+
484
+ ### Evaluation Results
485
+
486
+ The results of ethics and safety evaluations are within acceptable thresholds
487
+ for meeting [internal policies][safety-policies] for categories such as child
488
+ safety, content safety, representational harms, memorization, large-scale harms.
489
+ On top of robust internal evaluations, the results of well-known safety
490
+ benchmarks like BBQ, BOLD, Winogender, Winobias, RealToxicity, and TruthfulQA
491
+ are shown here.

507
+ ## Dangerous Capability Evaluations
508
+
509
+ ### Evaluation Approach
510
+
511
+ We evaluated a range of dangerous capabilities:
512
+
513
+ - **Offensive cybersecurity:** To assess the model's potential for misuse in
514
+ cybersecurity contexts, we utilized both publicly available
515
+ Capture-the-Flag (CTF) platforms like InterCode-CTF and Hack the Box, as
516
+ well as internally developed CTF challenges. These evaluations measure the
517
+ model's ability to exploit vulnerabilities and gain unauthorized access in
518
+ simulated environments.
519
+ - **Self-proliferation:** We evaluated the model's capacity for
520
+ self-proliferation by designing tasks that involve resource acquisition, code
521
+ execution, and interaction with remote systems. These evaluations assess
522
+ the model's ability to independently replicate and spread.
523
+ - **Persuasion:** To evaluate the model's capacity for persuasion and
524
+ deception, we conducted human persuasion studies. These studies involved
525
+ scenarios that measure the model's ability to build rapport, influence
526
+ beliefs, and elicit specific actions from human participants.
527
+
528
+ ### Evaluation Results
529
+
530
+ All evaluations are described in detail in
531
+ [Evaluating Frontier Models for Dangerous Capabilities][eval-danger]

601
+ ## Usage and Limitations
602
+
603
+ These models have certain limitations that users should be aware of.
604
+
605
+ ### Intended Usage
606
+
607
+ Open Large Language Models (LLMs) have a wide range of applications across
608
+ various industries and domains. The following list of potential uses is not
609
+ comprehensive. The purpose of this list is to provide contextual information
610
+ about the possible use-cases that the model creators considered as part of model
611
+ training and development.
612
+
613
+ * Content Creation and Communication
614
+ * Text Generation: These models can be used to generate creative text formats
615
+ such as poems, scripts, code, marketing copy, and email drafts.
616
+ * Chatbots and Conversational AI: Power conversational interfaces for customer
617
+ service, virtual assistants, or interactive applications.
618
+ * Text Summarization: Generate concise summaries of a text corpus, research
619
+ papers, or reports.
620
+ * Research and Education
621
+ * Natural Language Processing (NLP) Research: These models can serve as a
622
+ foundation for researchers to experiment with NLP techniques, develop
623
+ algorithms, and contribute to the advancement of the field.
624
+ * Language Learning Tools: Support interactive language learning experiences,
625
+ aiding in grammar correction or providing writing practice.
626
+ * Knowledge Exploration: Assist researchers in exploring large bodies of text
627
+ by generating summaries or answering questions about specific topics.
628
+
629
+ ### Limitations
630
+
631
+ * Training Data
632
+ * The quality and diversity of the training data significantly influence the
633
+ model's capabilities. Biases or gaps in the training data can lead to
634
+ limitations in the model's responses.
635
+ * The scope of the training dataset determines the subject areas the model can
636
+ handle effectively.
637
+ * Context and Task Complexity
638
+ * LLMs are better at tasks that can be framed with clear prompts and
639
+ instructions. Open-ended or highly complex tasks might be challenging.
640
+ * A model's performance can be influenced by the amount of context provided
641
+ (longer context generally leads to better outputs, up to a certain point).
642
+ * Language Ambiguity and Nuance
643
+ * Natural language is inherently complex. LLMs might struggle to grasp subtle
644
+ nuances, sarcasm, or figurative language.
645
+ * Factual Accuracy
646
+ * LLMs generate responses based on information they learned from their
647
+ training datasets, but they are not knowledge bases. They may generate
648
+ incorrect or outdated factual statements.
649
+ * Common Sense
650
+ * LLMs rely on statistical patterns in language. They might lack the ability
651
+ to apply common sense reasoning in certain situations.
652
+
653
+ ### Ethical Considerations and Risks
654
+
655
+ The development of large language models (LLMs) raises several ethical concerns.
656
+ In creating an open model, we have carefully considered the following:
657
+
658
+ * Bias and Fairness
659
+ * LLMs trained on large-scale, real-world text data can reflect socio-cultural
660
+ biases embedded in the training material. These models underwent careful
661
+ scrutiny, input data pre-processing described and posterior evaluations
662
+ reported in this card.
663
+ * Misinformation and Misuse
664
+ * LLMs can be misused to generate text that is false, misleading, or harmful.
665
+ * Guidelines are provided for responsible use with the model, see the
666
+ [Responsible Generative AI Toolkit][rai-toolkit].
667
+ * Transparency and Accountability:
668
+ * This model card summarizes details on the models' architecture,
669
+ capabilities, limitations, and evaluation processes.
670
+ * A responsibly developed open model offers the opportunity to share
671
+ innovation by making LLM technology accessible to developers and researchers
672
+ across the AI ecosystem.
673
+
674
+ Risks identified and mitigations:
675
+
676
+ * Perpetuation of biases: It's encouraged to perform continuous monitoring
677
+ (using evaluation metrics, human review) and the exploration of de-biasing
678
+ techniques during model training, fine-tuning, and other use cases.
679
+ * Generation of harmful content: Mechanisms and guidelines for content safety
680
+ are essential. Developers are encouraged to exercise caution and implement
681
+ appropriate content safety safeguards based on their specific product policies
682
+ and application use cases.
683
+ * Misuse for malicious purposes: Technical limitations and developer and
684
+ end-user education can help mitigate against malicious applications of LLMs.
685
+ Educational resources and reporting mechanisms for users to flag misuse are
686
+ provided. Prohibited uses of Gemma models are outlined in the
687
+ [Gemma Prohibited Use Policy][prohibited-use].
688
+ * Privacy violations: Models were trained on data filtered for removal of PII
689
+ (Personally Identifiable Information). Developers are encouraged to adhere to
690
+ privacy regulations with privacy-preserving techniques.
691
+
692
+ ### Benefits
693
+
694
+ At the time of release, this family of models provides high-performance open
695
+ large language model implementations designed from the ground up for Responsible
696
+ AI development compared to similarly sized models.
697
+
698
+ Using the benchmark evaluation metrics described in this document, these models
699
+ have shown to provide superior performance to other, comparably-sized open model
700
+ alternatives.
