## Model Information
|
31 |
-
|
32 |
-
Summary description and brief definition of inputs and outputs.
|
33 |
-
|
34 |
-
### Description
|
35 |
-
|
36 |
-
Gemma is a family of lightweight, state-of-the-art open models from Google,
|
37 |
-
built from the same research and technology used to create the Gemini models.
|
38 |
-
They are text-to-text, decoder-only large language models, available in English,
|
39 |
-
with open weights for both pre-trained variants and instruction-tuned variants.
|
40 |
-
Gemma models are well-suited for a variety of text generation tasks, including
|
41 |
-
question answering, summarization, and reasoning. Their relatively small size
|
42 |
-
makes it possible to deploy them in environments with limited resources such as
|
43 |
-
a laptop, desktop or your own cloud infrastructure, democratizing access to
|
44 |
-
state of the art AI models and helping foster innovation for everyone.
|
45 |
-
|
46 |
-
### Usage
|
47 |
-
|
48 |
-
Below we share some code snippets on how to get quickly started with running the model. First, install the Transformers library with:
|
49 |
-
```sh
|
50 |
-
pip install -U transformers
|
51 |
-
```
|
52 |
-
|
53 |
-
Then, copy the snippet from the section that is relevant for your usecase.
|
54 |

#### Running the model on a single / multi GPU
|
79 |
-
|
80 |
-
```python
|
81 |
-

-
input_text = "Write me a poem about Machine Learning."
|
93 |
-
input_ids = tokenizer(input_text, return_tensors="pt").to("cuda")
|
94 |
-
|
95 |
-
outputs = model.generate(**input_ids, max_new_tokens=32)
|
96 |
-
print(tokenizer.decode(outputs[0]))
|
97 |

```
|
98 |
-
|

You can ensure the correct chat template is applied by using `tokenizer.apply_chat_template` as follows:
|
100 |
-
```python
|
101 |
-
messages = [
|
102 |
-
{"role": "user", "content": "Write me a poem about Machine Learning."},
|
103 |
-
]
|
104 |
-
input_ids = tokenizer.apply_chat_template(messages, return_tensors="pt", return_dict=True).to("cuda")
|
105 |
-
|
106 |
-
outputs = model.generate(**input_ids, max_new_tokens=256)
|
107 |
-
print(tokenizer.decode(outputs[0]))
|

#### Running the model on a GPU using different precisions
|
112 |
-
|
113 |
-
The native weights of this model were exported in `bfloat16` precision.
|
114 |
-
|
115 |
-
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.
|
116 |
-
|
117 |
-

-
[Torch compile](https://pytorch.org/tutorials/intermediate/torch_compile_tutorial.html) is a method for speeding-up the
|
206 |
-
inference of PyTorch modules. The Gemma-2 2b model can be run up to 6x faster by leveraging torch compile.
|
207 |
-
|
208 |
-
Note that two warm-up steps are required before the full inference speed is realised:

### Chat Template
|
261 |
-
|
262 |
-
The instruction-tuned models use a chat template that must be adhered to for conversational use.
|
263 |
-
The easiest way to apply it is using the tokenizer's built-in chat template, as shown in the following snippet.
|
264 |
-
|
265 |
-
Let's load the model and apply the chat template to a conversation. In this example, we'll start with a single user interaction:
|
266 |
-
|
267 |
-
```py
|
268 |
-
from transformers import AutoTokenizer, AutoModelForCausalLM
|
269 |
-
import transformers
|
270 |
-
import torch
|
271 |
-
|
272 |
-
model_id = "google/gemma-2-2b-it"
|
273 |
-
dtype = torch.bfloat16
|
274 |
-
|
275 |
-
tokenizer = AutoTokenizer.from_pretrained(model_id)
|
276 |
-
model = AutoModelForCausalLM.from_pretrained(
|
277 |
-
model_id,
|
278 |
-
device_map="cuda",
|
279 |
-
torch_dtype=dtype,)
|
280 |
-
|
281 |
-
chat = [
|
282 |
-
{ "role": "user", "content": "Write a hello world program" },
|
283 |
-
]
|
284 |
-
prompt = tokenizer.apply_chat_template(chat, tokenize=False, add_generation_prompt=True)
|
285 |
-
```
|
286 |
-
|
287 |
-
At this point, the prompt contains the following text:
|
288 |
-
|
289 |
-
```
|
290 |
-
<bos><start_of_turn>user
|
291 |
-
Write a hello world program<end_of_turn>
|
292 |
-
<start_of_turn>model
|
293 |
-
```
|
294 |
-
|
295 |
-
As you can see, each turn is preceded by a `<start_of_turn>` delimiter and then the role of the entity
|
296 |
-
(either `user`, for content supplied by the user, or `model` for LLM responses). Turns finish with
|
297 |
-
the `<end_of_turn>` token.
|
298 |
-
|
299 |
-
You can follow this format to build the prompt manually, if you need to do it without the tokenizer's
|
300 |
-
chat template.
|
301 |
-
|
302 |
-
After the prompt is ready, generation can be performed like this:
|
303 |
-
|
304 |
-
```py
|
305 |
-
inputs = tokenizer.encode(prompt, add_special_tokens=False, return_tensors="pt")
|
306 |
-
outputs = model.generate(input_ids=inputs.to(model.device), max_new_tokens=150)
|
307 |
-
print(tokenizer.decode(outputs[0]))
|
308 |
-
```
|
309 |
-
|
310 |
-
### Inputs and outputs
|
311 |
-
|
312 |
-
* **Input:** Text string, such as a question, a prompt, or a document to be
|
313 |
-
summarized.
|
314 |
-
* **Output:** Generated English-language text in response to the input, such
|
315 |
-
as an answer to a question, or a summary of a document.

## Model Data

-
Data used for model training and how the data was processed.
|
333 |
-
|
334 |
-
### Training Dataset
|
335 |
-
|
336 |
-
These models were trained on a dataset of text data that includes a wide variety
|
337 |
-
of sources. The 27B model was trained with 13 trillion tokens, the 9B model was
|
338 |
-
trained with 8 trillion tokens, and 2B model was trained with 2 trillion tokens.
|
339 |
-
Here are the key components:
|
340 |
-
|
341 |
-
* Web Documents: A diverse collection of web text ensures the model is exposed
|
342 |
-
to a broad range of linguistic styles, topics, and vocabulary. Primarily
|
343 |
-
English-language content.
|
344 |
-
* Code: Exposing the model to code helps it to learn the syntax and patterns of
|
345 |
-
programming languages, which improves its ability to generate code or
|
346 |
-
understand code-related questions.
|
347 |
-
* Mathematics: Training on mathematical text helps the model learn logical
|
348 |
-
reasoning, symbolic representation, and to address mathematical queries.
|
349 |
-
|
350 |
-
The combination of these diverse data sources is crucial for training a powerful
|
351 |
-
language model that can handle a wide variety of different tasks and text
|
352 |
-
formats.
|
353 |
-
|
354 |
-
### Data Preprocessing
|
355 |
-
|
356 |
-
Here are the key data cleaning and filtering methods applied to the training
|
357 |
-
data:
|
358 |
-
|
359 |
-
* CSAM Filtering: Rigorous CSAM (Child Sexual Abuse Material) filtering was
|
360 |
-
applied at multiple stages in the data preparation process to ensure the
|
361 |
-
exclusion of harmful and illegal content.
|
362 |
-
* Sensitive Data Filtering: As part of making Gemma pre-trained models safe and
|
363 |
-
reliable, automated techniques were used to filter out certain personal
|
364 |
-
information and other sensitive data from training sets.
|
365 |
-
* Additional methods: Filtering based on content quality and safety in line with
|
366 |
-
[our policies][safety-policies].
|
367 |
-
|
368 |
-
## Implementation Information
|
369 |
-
|
370 |
-
Details about the model internals.
|
371 |
-
|
372 |
-
### Hardware
|
373 |
-
|
374 |
-
Gemma was trained using the latest generation of
|
375 |
-
[Tensor Processing Unit (TPU)][tpu] hardware (TPUv5p).
|
376 |
-
|
377 |
-
Training large language models requires significant computational power. TPUs,
|
378 |
-
designed specifically for matrix operations common in machine learning, offer
|
379 |
-
several advantages in this domain:
|
380 |
-
|
381 |
-
* Performance: TPUs are specifically designed to handle the massive computations
|
382 |
-
involved in training LLMs. They can speed up training considerably compared to
|
383 |
-
CPUs.
|
384 |
-
* Memory: TPUs often come with large amounts of high-bandwidth memory, allowing
|
385 |
-
for the handling of large models and batch sizes during training. This can
|
386 |
-
lead to better model quality.
|
387 |
-
* Scalability: TPU Pods (large clusters of TPUs) provide a scalable solution for
|
388 |
-
handling the growing complexity of large foundation models. You can distribute
|
389 |
-
training across multiple TPU devices for faster and more efficient processing.
|
390 |
-
* Cost-effectiveness: In many scenarios, TPUs can provide a more cost-effective
|
391 |
-
solution for training large models compared to CPU-based infrastructure,
|
392 |
-
especially when considering the time and resources saved due to faster
|
393 |
-
training.
|
394 |
-
* These advantages are aligned with
|
395 |
-
[Google's commitments to operate sustainably][sustainability].
|
396 |
-
|
397 |
-
### Software
|
398 |
-
|
399 |
-
Training was done using [JAX][jax] and [ML Pathways][ml-pathways].
|
400 |
-
|
401 |
-
JAX allows researchers to take advantage of the latest generation of hardware,
|
402 |
-
including TPUs, for faster and more efficient training of large models.
|
403 |
-
|
404 |
-
ML Pathways is Google's latest effort to build artificially intelligent systems
|
405 |
-
capable of generalizing across multiple tasks. This is specially suitable for
|
406 |
-
[foundation models][foundation-models], including large language models like
|
407 |
-
these ones.
|
408 |
-
|
409 |
-
Together, JAX and ML Pathways are used as described in the
|
410 |
-
[paper about the Gemini family of models][gemini-2-paper]; "the 'single
|
411 |
-
controller' programming model of Jax and Pathways allows a single Python
|
412 |
-
process to orchestrate the entire training run, dramatically simplifying the
|
413 |
-
development workflow."

446 |
-
Ethics and safety evaluation approach and results.
|
447 |
-
|
448 |
-
### Evaluation Approach
|
449 |
-
|
450 |
-
Our evaluation methods include structured evaluations and internal red-teaming
|
451 |
-
testing of relevant content policies. Red-teaming was conducted by a number of
|
452 |
-
different teams, each with different goals and human evaluation metrics. These
|
453 |
-
models were evaluated against a number of different categories relevant to
|
454 |
-
ethics and safety, including:
|
455 |
-
|
456 |
-
* Text-to-Text Content Safety: Human evaluation on prompts covering safety
|
457 |
-
policies including child sexual abuse and exploitation, harassment, violence
|
458 |
-
and gore, and hate speech.
|
459 |
-
* Text-to-Text Representational Harms: Benchmark against relevant academic
|
460 |
-
datasets such as [WinoBias][winobias] and [BBQ Dataset][bbq].
|
461 |
-
* Memorization: Automated evaluation of memorization of training data, including
|
462 |
-
the risk of personally identifiable information exposure.
|
463 |
-
* Large-scale harm: Tests for "dangerous capabilities," such as chemical,
|
464 |
-
biological, radiological, and nuclear (CBRN) risks.
|
465 |
-
|
466 |
-
### Evaluation Results
|
467 |
-
|
468 |
-
The results of ethics and safety evaluations are within acceptable thresholds
|
469 |
-
for meeting [internal policies][safety-policies] for categories such as child
|
470 |
-
safety, content safety, representational harms, memorization, large-scale harms.
|
471 |
-
On top of robust internal evaluations, the results of well-known safety
|
472 |
-
benchmarks like BBQ, BOLD, Winogender, Winobias, RealToxicity, and TruthfulQA
|
473 |
-
are shown here.

## Dangerous Capability Evaluations
|
490 |
-
|
491 |
-
### Evaluation Approach
|
492 |
-
|
493 |
-
We evaluated a range of dangerous capabilities:
|
494 |
-
|
495 |
-
- **Offensive cybersecurity:** To assess the model's potential for misuse in
|
496 |
-
cybersecurity contexts, we utilized both publicly available
|
497 |
-
Capture-the-Flag (CTF) platforms like InterCode-CTF and Hack the Box, as
|
498 |
-
well as internally developed CTF challenges. These evaluations measure the
|
499 |
-
model's ability to exploit vulnerabilities and gain unauthorized access in
|
500 |
-
simulated environments.
|
501 |
-
- **Self-proliferation:** We evaluated the model's capacity for
|
502 |
-
self-proliferation by designing tasks that involve resource acquisition, code
|
503 |
-
execution, and interaction with remote systems. These evaluations assess
|
504 |
-
the model's ability to independently replicate and spread.
|
505 |
-
- **Persuasion:** To evaluate the model's capacity for persuasion and
|
506 |
-
deception, we conducted human persuasion studies. These studies involved
|
507 |
-
scenarios that measure the model's ability to build rapport, influence
|
508 |
-
beliefs, and elicit specific actions from human participants.
|
509 |
-
|
510 |
-
### Evaluation Results

## Usage and Limitations
|
584 |
-
|
585 |
-
These models have certain limitations that users should be aware of.
|
586 |
-
|
587 |
-
### Intended Usage
|
588 |
-
|
589 |
-
Open Large Language Models (LLMs) have a wide range of applications across
|
590 |
-
various industries and domains. The following list of potential uses is not
|
591 |
-
comprehensive. The purpose of this list is to provide contextual information
|
592 |
-
about the possible use-cases that the model creators considered as part of model
|
593 |
-
training and development.
|
594 |
-
|
595 |
-
* Content Creation and Communication
|
596 |
-
* Text Generation: These models can be used to generate creative text formats
|
597 |
-
such as poems, scripts, code, marketing copy, and email drafts.
|
598 |
-
* Chatbots and Conversational AI: Power conversational interfaces for customer
|
599 |
-
service, virtual assistants, or interactive applications.
|
600 |
-
* Text Summarization: Generate concise summaries of a text corpus, research
|
601 |
-
papers, or reports.
|
602 |
-
* Research and Education
|
603 |
-
* Natural Language Processing (NLP) Research: These models can serve as a
|
604 |
-
foundation for researchers to experiment with NLP techniques, develop
|
605 |
-
algorithms, and contribute to the advancement of the field.
|
606 |
-
* Language Learning Tools: Support interactive language learning experiences,
|
607 |
-
aiding in grammar correction or providing writing practice.
|
608 |
-
* Knowledge Exploration: Assist researchers in exploring large bodies of text
|
609 |
-
by generating summaries or answering questions about specific topics.
|
610 |
-
|
611 |
-
### Limitations
|
612 |
-
|
613 |
-
* Training Data
|
614 |
-
* The quality and diversity of the training data significantly influence the
|
615 |
-
model's capabilities. Biases or gaps in the training data can lead to
|
616 |
-
limitations in the model's responses.
|
617 |
-
* The scope of the training dataset determines the subject areas the model can
|
618 |
-
handle effectively.
|
619 |
-
* Context and Task Complexity
|
620 |
-
* LLMs are better at tasks that can be framed with clear prompts and
|
621 |
-
instructions. Open-ended or highly complex tasks might be challenging.
|
622 |
-
* A model's performance can be influenced by the amount of context provided
|
623 |
-
(longer context generally leads to better outputs, up to a certain point).
|
624 |
-
* Language Ambiguity and Nuance
|
625 |
-
* Natural language is inherently complex. LLMs might struggle to grasp subtle
|
626 |
-
nuances, sarcasm, or figurative language.
|
627 |
-
* Factual Accuracy
|
628 |
-
* LLMs generate responses based on information they learned from their
|
629 |
-
training datasets, but they are not knowledge bases. They may generate
|
630 |
-
incorrect or outdated factual statements.
|
631 |
-
* Common Sense
|
632 |
-
* LLMs rely on statistical patterns in language. They might lack the ability
|
633 |
-
to apply common sense reasoning in certain situations.
|
634 |
-
|
635 |
-
### Ethical Considerations and Risks
|
636 |
-
|
637 |
-
The development of large language models (LLMs) raises several ethical concerns.
|
638 |
-
In creating an open model, we have carefully considered the following:
|
639 |
-
|
640 |
-
* Bias and Fairness
|
641 |
-
* LLMs trained on large-scale, real-world text data can reflect socio-cultural
|
642 |
-
biases embedded in the training material. These models underwent careful
|
643 |
-
scrutiny, input data pre-processing described and posterior evaluations
|
644 |
-
reported in this card.
|
645 |
-
* Misinformation and Misuse
|
646 |
-
* LLMs can be misused to generate text that is false, misleading, or harmful.
|
647 |
-
* Guidelines are provided for responsible use with the model, see the
|
648 |
-
[Responsible Generative AI Toolkit][rai-toolkit].
|
649 |
-
* Transparency and Accountability:
|
650 |
-
* This model card summarizes details on the models' architecture,
|
651 |
-
capabilities, limitations, and evaluation processes.
|
652 |
-
* A responsibly developed open model offers the opportunity to share
|
653 |
-
innovation by making LLM technology accessible to developers and researchers
|
654 |
-
across the AI ecosystem.
|
655 |
-
|
656 |
-
Risks identified and mitigations:
|
657 |
-
|
658 |
-
* Perpetuation of biases: It's encouraged to perform continuous monitoring
|
659 |
-
(using evaluation metrics, human review) and the exploration of de-biasing
|
660 |
-
techniques during model training, fine-tuning, and other use cases.
|
661 |
-
* Generation of harmful content: Mechanisms and guidelines for content safety
|
662 |
-
are essential. Developers are encouraged to exercise caution and implement
|
663 |
-
appropriate content safety safeguards based on their specific product policies
|
664 |
-
and application use cases.
|
665 |
-
* Misuse for malicious purposes: Technical limitations and developer and
|
666 |
-
end-user education can help mitigate against malicious applications of LLMs.
|
667 |
-
Educational resources and reporting mechanisms for users to flag misuse are
|
668 |
-
provided. Prohibited uses of Gemma models are outlined in the
|
669 |
-
[Gemma Prohibited Use Policy][prohibited-use].
|
670 |
-
* Privacy violations: Models were trained on data filtered for removal of PII
|
671 |
-
(Personally Identifiable Information). Developers are encouraged to adhere to
|
672 |
-
privacy regulations with privacy-preserving techniques.
|
673 |
-
|
674 |
-
