# Gemma v2 27b Instruct - llamafile |
|
|
|
Gemma v2 is a large language model released by Google on Jun 27th 2024. |
|
|
|
- Model creator: [Google](https://huggingface.co/google/) |
|
- Original model: [google/gemma-2-27b-it](https://huggingface.co/google/gemma-2-27b-it) |
|
|
|
The model is packaged into executable weights, which we call |
|
[llamafiles](https://github.com/Mozilla-Ocho/llamafile). This makes it |
|
easy to use the model on Linux, MacOS, Windows, FreeBSD, OpenBSD 7.3, |
|
and NetBSD for AMD64 and ARM64. |
|
|
|
*Software Last Updated: 2024-11-01* |
|
|
|
## Quickstart |
|
|
|
To get started, you need both the Gemma weights, and the llamafile |
|
software. Both of them are included in a single file, which can be |
|
downloaded and run as follows: |
|
|
|
``` |
|
wget https://huggingface.co/Mozilla/gemma-2-27b-it-llamafile/resolve/main/gemma-2-27b-it.Q6_K.llamafile |
|
chmod +x gemma-2-27b-it.Q6_K.llamafile |
|
./gemma-2-27b-it.Q6_K.llamafile |
|
``` |
|
|
|
The default mode of operation for these llamafiles is our new command |
|
line chatbot interface. |

|
Having **trouble?** See the ["Gotchas" |
|
section](https://github.com/mozilla-ocho/llamafile/?tab=readme-ov-file#gotchas-and-troubleshooting) |
|
of the README. |
|
|
|
## Usage |
|
|
|
By default, llamafile launches a chatbot in the terminal, and a server |
|
in the background. The chatbot is mostly self-explanatory. You can type |
|
`/help` for further details. See the [llamafile v0.8.15 release |
|
notes](https://github.com/Mozilla-Ocho/llamafile/releases/tag/0.8.15) |
|
for documentation on our newest chatbot features. |
|
|
|
To instruct Gemma to do role playing, you can customize the system |
|
prompt as follows: |
|
|
|
``` |
|
./gemma-2-27b-it.Q6_K.llamafile --chat -p "you are mosaic's godzilla" |
|
``` |
|
|
|
To view the man page, run: |
|
|
|
``` |
|
./gemma-2-27b-it.Q6_K.llamafile --help |
|
``` |
|
|
|
To send a request to the OpenAI API compatible llamafile server, try: |
|
|
|
``` |
|
curl http://localhost:8080/v1/chat/completions \ |
|
-H "Content-Type: application/json" \ |
|
-d '{ |
|
"model": "gemma-27b-it", |
|
"messages": [{"role": "user", "content": "Say this is a test!"}], |
|
"temperature": 0.0 |
|
}' |
|
``` |
|
|
|
If you don't want the chatbot and you only want to run the server: |
|
|
|
``` |
|
./gemma-2-27b-it.Q6_K.llamafile --server --nobrowser --host 0.0.0.0 |
|
``` |
|
|
|
An advanced CLI mode is provided that's useful for shell scripting. You |
|
can use it by passing the `--cli` flag. For additional help on how it |
|
may be used, pass the `--help` flag. |
|
|
|
``` |
|
./gemma-2-27b-it.Q6_K.llamafile --cli -p 'four score and seven' --log-disable |
|
``` |
|
|
|
You then need to fill out the prompt / history template (see below). |
|
|
|
For further information, please see the [llamafile |
|
README](https://github.com/mozilla-ocho/llamafile/). |
|
|
|
## Troubleshooting |
|
|
|
Having **trouble?** See the ["Gotchas" |
|
section](https://github.com/mozilla-ocho/llamafile/?tab=readme-ov-file#gotchas-and-troubleshooting) |
|
of the README. |
|
|
|
On Linux, the way to avoid run-detector errors is to install the APE |
|
interpreter. |
|
|
|
```sh |
|
sudo wget -O /usr/bin/ape https://cosmo.zip/pub/cosmos/bin/ape-$(uname -m).elf |
|
sudo chmod +x /usr/bin/ape |
|
sudo sh -c "echo ':APE:M::MZqFpD::/usr/bin/ape:' >/proc/sys/fs/binfmt_misc/register" |
|
sudo sh -c "echo ':APE-jart:M::jartsr::/usr/bin/ape:' >/proc/sys/fs/binfmt_misc/register" |
|
``` |
|
|
|
On Windows there's a 4GB limit on executable sizes. This means you |
|
should download the Q2\_K llamafile. For better quality, consider |
|
instead downloading the official llamafile release binary from |
|
<https://github.com/Mozilla-Ocho/llamafile/releases>, renaming it to |
|
have the .exe file extension, and then saying: |
|
|
|
``` |
|
.\llamafile-0.8.15.exe -m gemma-2-27b-it.Q6_K.llamafile |
|
``` |
|
|
|
That will overcome the Windows 4GB file size limit, allowing you to |
|
benefit from bigger better models. |
|
|
|
## Context Window |
|
|
|
This model has a max context window size of 8k tokens. By default, a |
|
context window size of 8192 tokens is used. You may limit the context |
|
window size by passing the `-c N` flag. |
|
|
|
## GPU Acceleration |
|
|
|
On GPUs with sufficient RAM, the `-ngl 999` flag may be passed to use |
|
the system's NVIDIA or AMD GPU(s). On Windows, only the graphics card |
|
driver needs to be installed if you own an NVIDIA GPU. On Windows, if |
|
you have an AMD GPU, you should install the ROCm SDK v6.1 and then pass |
|
the flags `--recompile --gpu amd` the first time you run your llamafile. |
|
|
|
On NVIDIA GPUs, by default, the prebuilt tinyBLAS library is used to |
|
perform matrix multiplications. This is open source software, but it |
|
doesn't go as fast as closed source cuBLAS. If you have the CUDA SDK |
|
installed on your system, then you can pass the `--recompile` flag to |
|
build a GGML CUDA library just for your system that uses cuBLAS. This |
|
ensures you get maximum performance. |
|
|
|
For further information, please see the [llamafile |
|
README](https://github.com/mozilla-ocho/llamafile/). |
|
|
|
## About Upload Limits |
|
|
|
Files which exceed the Hugging Face 50GB upload limit have a .cat𝑋 |
|
extension. You need to use the `cat` command locally to turn them back |
|
into a single file, using the same order. |
|
|
|
## About llamafile |
|
|
|
llamafile is a new format introduced by Mozilla on Nov 20th 2023. It |
|
uses Cosmopolitan Libc to turn LLM weights into runnable llama.cpp |
|
binaries that run on the stock installs of six OSes for both ARM64 and |
|
AMD64. |
|
|
|
## About Quantization Formats |
|
|
|
This model works well with any quantization format. Q6\_K is the best |
|
choice overall here. |
|
|
|
## Testing |
|
|
|
We tested that the gemma2 27b q6\_k llamafile produces nearly identical |
|
responses to the Gemma2 model hosted by Google on aistudio.google.com |
|
when temperature is set to zero. |
|
|
|
![screenshot of llamafile producing same output as google's hosted gemma service](gemma-proof.png) |
|
|
|
Therefore, it is our belief, that the llamafile software faithfully |
|
implements the gemma model. If you should encounter any divergences, |
|
then try using the BF16 weights, which have the original fidelity. |

## Model Information |
|
|
|
Summary description and brief definition of inputs and outputs. |
|
|
|
### Description |
|
|
|
Gemma is a family of lightweight, state-of-the-art open models from Google, |
|
built from the same research and technology used to create the Gemini models. |
|
They are text-to-text, decoder-only large language models, available in English, |
|
with open weights for both pre-trained variants and instruction-tuned variants. |
|
Gemma models are well-suited for a variety of text generation tasks, including |
|
question answering, summarization, and reasoning. Their relatively small size |
|
makes it possible to deploy them in environments with limited resources such as |
|
a laptop, desktop or your own cloud infrastructure, democratizing access to |
|
state of the art AI models and helping foster innovation for everyone. |
|
|
|
### Usage |
|
|
|
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. |
|
|
|
|
|
#### Running the model on a single / multi GPU |
|
|
|
|
|
```python |
|
# pip install accelerate |
|
from transformers import AutoTokenizer, AutoModelForCausalLM |
|
import torch |
|
|
|
tokenizer = AutoTokenizer.from_pretrained("google/gemma-2-27b-it") |
|
model = AutoModelForCausalLM.from_pretrained( |
|
"google/gemma-2-27b-it", |
|
device_map="auto", |
|
torch_dtype=torch.bfloat16 |
|
) |
|
|
|
input_text = "Write me a poem about Machine Learning." |
|
input_ids = tokenizer(input_text, return_tensors="pt").to("cuda") |
|
|
|
outputs = model.generate(**input_ids) |
|
print(tokenizer.decode(outputs[0])) |
|
``` |
|
|
|
<a name="precisions"></a> |
|
#### Running the model on a GPU using different precisions |
|
|
|
The native weights of this model were exported in `bfloat16` precision. You can use `float16`, which may be faster on certain hardware, indicating the `torch_dtype` when loading the model. For convenience, the `float16` revision of the repo contains a copy of the weights already converted to that precision. |
|
|
|
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. |
|
|
|
* _Using `torch.float16`_ |
|
|
|
```python |
|
# pip install accelerate |
|
from transformers import AutoTokenizer, AutoModelForCausalLM |
|
import torch |
|
|
|
tokenizer = AutoTokenizer.from_pretrained("google/gemma-2-27b-it") |
|
model = AutoModelForCausalLM.from_pretrained( |
|
"google/gemma-2-27b-it", |
|
device_map="auto", |
|
torch_dtype=torch.float16, |
|
revision="float16", |
|
) |
|
|
|
input_text = "Write me a poem about Machine Learning." |
|
input_ids = tokenizer(input_text, return_tensors="pt").to("cuda") |
|
|
|
outputs = model.generate(**input_ids) |
|
print(tokenizer.decode(outputs[0])) |
|
``` |
|
|
|
* _Using `torch.bfloat16`_ |
|
|
|
```python |
|
# pip install accelerate |
|
from transformers import AutoTokenizer, AutoModelForCausalLM |
|
|
|
tokenizer = AutoTokenizer.from_pretrained("google/gemma-2-27b-it") |
|
model = AutoModelForCausalLM.from_pretrained( |
|
"google/gemma-2-27b-it", |
|
device_map="auto", |
|
torch_dtype=torch.bfloat16) |
|
|
|
input_text = "Write me a poem about Machine Learning." |
|
input_ids = tokenizer(input_text, return_tensors="pt").to("cuda") |
|
|
|
outputs = model.generate(**input_ids) |
|
print(tokenizer.decode(outputs[0])) |
|
``` |
|
|
|
* _Upcasting to `torch.float32`_ |
|
|
|
```python |
|
# pip install accelerate |
|
from transformers import AutoTokenizer, AutoModelForCausalLM |
|
|
|
tokenizer = AutoTokenizer.from_pretrained("google/gemma-2-27b-it") |
|
model = AutoModelForCausalLM.from_pretrained( |
|
"google/gemma-2-27b-it", |
|
device_map="auto" |
|
) |
|
|
|
input_text = "Write me a poem about Machine Learning." |
|
input_ids = tokenizer(input_text, return_tensors="pt").to("cuda") |
|
|
|
outputs = model.generate(**input_ids) |
|
print(tokenizer.decode(outputs[0])) |
|
``` |
|
|
|
#### Quantized Versions through `bitsandbytes` |
|
|
|
* _Using 8-bit precision (int8)_ |
|
|
|
```python |
|
# pip install bitsandbytes accelerate |
|
from transformers import AutoTokenizer, AutoModelForCausalLM, BitsAndBytesConfig |
|
|
|
quantization_config = BitsAndBytesConfig(load_in_8bit=True) |
|
|
|
tokenizer = AutoTokenizer.from_pretrained("google/gemma-2-27b-it") |
|
model = AutoModelForCausalLM.from_pretrained( |
|
"google/gemma-2-27b-it", |
|
quantization_config=quantization_config) |
|
|
|
input_text = "Write me a poem about Machine Learning." |
|
input_ids = tokenizer(input_text, return_tensors="pt").to("cuda") |
|
|
|
outputs = model.generate(**input_ids) |
|
print(tokenizer.decode(outputs[0])) |
|
``` |
|
|
|
* _Using 4-bit precision_ |
|
|
|
```python |
|
# pip install bitsandbytes accelerate |
|
from transformers import AutoTokenizer, AutoModelForCausalLM, BitsAndBytesConfig |
|
|
|
quantization_config = BitsAndBytesConfig(load_in_4bit=True) |
|
|
|
tokenizer = AutoTokenizer.from_pretrained("google/gemma-2-27b-it") |
|
model = AutoModelForCausalLM.from_pretrained( |
|
"google/gemma-2-27b-it", |
|
quantization_config=quantization_config) |
|
|
|
input_text = "Write me a poem about Machine Learning." |
|
input_ids = tokenizer(input_text, return_tensors="pt").to("cuda") |
|
|
|
outputs = model.generate(**input_ids) |
|
print(tokenizer.decode(outputs[0])) |
|
``` |
|
|
|
|
|
#### Other optimizations |
|
|
|
* _Flash Attention 2_ |
|
|
|
First make sure to install `flash-attn` in your environment `pip install flash-attn` |
|
|
|
```diff |
|
model = AutoModelForCausalLM.from_pretrained( |
|
model_id, |
|
torch_dtype=torch.float16, |
|
+ attn_implementation="flash_attention_2" |
|
).to(0) |
|
``` |
|
|
|
### Chat Template |
|
|
|
The instruction-tuned models use a chat template that must be adhered to for conversational use. |
|
The easiest way to apply it is using the tokenizer's built-in chat template, as shown in the following snippet. |
|
|
|
Let's load the model and apply the chat template to a conversation. In this example, we'll start with a single user interaction: |
|
|
|
```py |
|
from transformers import AutoTokenizer, AutoModelForCausalLM |
|
import transformers |
|
import torch |
|
|
|
model_id = "google/gemma-2-27b-it" |
|
dtype = torch.bfloat16 |
|
|
|
tokenizer = AutoTokenizer.from_pretrained(model_id) |
|
model = AutoModelForCausalLM.from_pretrained( |
|
model_id, |
|
device_map="cuda", |
|
torch_dtype=dtype, |
|
) |
|
|
|
chat = [ |
|
{ "role": "user", "content": "Write a hello world program" }, |
|
] |
|
prompt = tokenizer.apply_chat_template(chat, tokenize=False, add_generation_prompt=True) |
|
``` |
|
|
|
At this point, the prompt contains the following text: |
|
|
|
``` |
|
<bos><start_of_turn>user |
|
Write a hello world program<end_of_turn> |
|
<start_of_turn>model |
|
``` |
|
|
|
As you can see, each turn is preceded by a `<start_of_turn>` delimiter and then the role of the entity |
|
(either `user`, for content supplied by the user, or `model` for LLM responses). Turns finish with |
|
the `<end_of_turn>` token. |
|
|
|
You can follow this format to build the prompt manually, if you need to do it without the tokenizer's |
|
chat template. |
|
|
|
After the prompt is ready, generation can be performed like this: |
|
|
|
```py |
|
inputs = tokenizer.encode(prompt, add_special_tokens=False, return_tensors="pt") |
|
outputs = model.generate(input_ids=inputs.to(model.device), max_new_tokens=150) |
|
print(tokenizer.decode(outputs[0])) |
|
``` |
|
|
|
### Inputs and outputs |
|
|
|
* **Input:** Text string, such as a question, a prompt, or a document to be |
|
summarized. |
|
* **Output:** Generated English-language text in response to the input, such |
|
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. |
|
|
|
### Training Dataset |
|
|
|
These models were trained on a dataset of text data that includes a wide variety of sources. The 27B model was trained with 13 trillion tokens and the 9B model was trained with 8 trillion tokens. |
|
Here are the key components: |
|
|
|
* Web Documents: A diverse collection of web text ensures the model is exposed |
|
to a broad range of linguistic styles, topics, and vocabulary. Primarily |
|
English-language content. |
|
* Code: Exposing the model to code helps it to learn the syntax and patterns of |
|
programming languages, which improves its ability to generate code or |
|
understand code-related questions. |
|
* Mathematics: Training on mathematical text helps the model learn logical |
|
reasoning, symbolic representation, and to address mathematical queries. |
|
|
|
The combination of these diverse data sources is crucial for training a powerful |
|
language model that can handle a wide variety of different tasks and text |
|
formats. |
|
|
|
### Data Preprocessing |
|
|
|
Here are the key data cleaning and filtering methods applied to the training |
|
data: |
|
|
|
* CSAM Filtering: Rigorous CSAM (Child Sexual Abuse Material) filtering was |
|
applied at multiple stages in the data preparation process to ensure the |
|
exclusion of harmful and illegal content. |
|
* Sensitive Data Filtering: As part of making Gemma pre-trained models safe and |
|
reliable, automated techniques were used to filter out certain personal |
|
information and other sensitive data from training sets. |
|
* Additional methods: Filtering based on content quality and safety in line with |
|
[our policies][safety-policies]. |
|
|
|
## Implementation Information |
|
|
|
Details about the model internals. |
|
|
|
### Hardware |
|
|
|
Gemma was trained using the latest generation of |
|
[Tensor Processing Unit (TPU)][tpu] hardware (TPUv5p). |
|
|
|
Training large language models requires significant computational power. TPUs, |
|
designed specifically for matrix operations common in machine learning, offer |
|
several advantages in this domain: |
|
|
|
* Performance: TPUs are specifically designed to handle the massive computations |
|
involved in training LLMs. They can speed up training considerably compared to |
|
CPUs. |
|
* Memory: TPUs often come with large amounts of high-bandwidth memory, allowing |
|
for the handling of large models and batch sizes during training. This can |
|
lead to better model quality. |
|
* Scalability: TPU Pods (large clusters of TPUs) provide a scalable solution for |
|
handling the growing complexity of large foundation models. You can distribute |
|
training across multiple TPU devices for faster and more efficient processing. |
|
* Cost-effectiveness: In many scenarios, TPUs can provide a more cost-effective |
|
solution for training large models compared to CPU-based infrastructure, |
|
especially when considering the time and resources saved due to faster |
|
training. |
|
* These advantages are aligned with |
|
[Google's commitments to operate sustainably][sustainability]. |
|
|
|
### Software |
|
|
|
Training was done using [JAX][jax] and [ML Pathways][ml-pathways]. |
|
|
|
JAX allows researchers to take advantage of the latest generation of hardware, |
|
including TPUs, for faster and more efficient training of large models. |
|
|
|
ML Pathways is Google's latest effort to build artificially intelligent systems |
|
capable of generalizing across multiple tasks. This is specially suitable for |
|
[foundation models][foundation-models], including large language models like |
|
these ones. |
|
|
|
Together, JAX and ML Pathways are used as described in the |
|
[paper about the Gemini family of models][gemini-2-paper]; "the 'single |
|
controller' programming model of Jax and Pathways allows a single Python |
|
process to orchestrate the entire training run, dramatically simplifying the |
|
development workflow." |

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

## Usage and Limitations |
|
|
|
These models have certain limitations that users should be aware of. |
|
|
|
### Intended Usage |
|
|
|
Open Large Language Models (LLMs) have a wide range of applications across |
|
various industries and domains. The following list of potential uses is not |
|
comprehensive. The purpose of this list is to provide contextual information |
|
about the possible use-cases that the model creators considered as part of model |
|
training and development. |
|
|
|
* Content Creation and Communication |
|
* Text Generation: These models can be used to generate creative text formats |
|
such as poems, scripts, code, marketing copy, and email drafts. |
|
* Chatbots and Conversational AI: Power conversational interfaces for customer |
|
service, virtual assistants, or interactive applications. |
|
* Text Summarization: Generate concise summaries of a text corpus, research |
|
papers, or reports. |
|
* Research and Education |
|
* Natural Language Processing (NLP) Research: These models can serve as a |
|
foundation for researchers to experiment with NLP techniques, develop |
|
algorithms, and contribute to the advancement of the field. |
|
* Language Learning Tools: Support interactive language learning experiences, |
|
aiding in grammar correction or providing writing practice. |
|
* Knowledge Exploration: Assist researchers in exploring large bodies of text |
|
by generating summaries or answering questions about specific topics. |
|
|
|
### Limitations |
|
|
|
* Training Data |
|
* The quality and diversity of the training data significantly influence the |
|
model's capabilities. Biases or gaps in the training data can lead to |
|
limitations in the model's responses. |
|
* The scope of the training dataset determines the subject areas the model can |
|
handle effectively. |
|
* Context and Task Complexity |
|
* LLMs are better at tasks that can be framed with clear prompts and |
|
instructions. Open-ended or highly complex tasks might be challenging. |
|
* A model's performance can be influenced by the amount of context provided |
|
(longer context generally leads to better outputs, up to a certain point). |
|
* Language Ambiguity and Nuance |
|
* Natural language is inherently complex. LLMs might struggle to grasp subtle |
|
nuances, sarcasm, or figurative language. |
|
* Factual Accuracy |
|
* LLMs generate responses based on information they learned from their |
|
training datasets, but they are not knowledge bases. They may generate |
|
incorrect or outdated factual statements. |
|
* Common Sense |
|
* LLMs rely on statistical patterns in language. They might lack the ability |
|
to apply common sense reasoning in certain situations. |
|
|
|
### Ethical Considerations and Risks |
|
|
|
The development of large language models (LLMs) raises several ethical concerns. |
|
In creating an open model, we have carefully considered the following: |
|
|
|
* Bias and Fairness |
|
* LLMs trained on large-scale, real-world text data can reflect socio-cultural |
|
biases embedded in the training material. These models underwent careful |
|
scrutiny, input data pre-processing described and posterior evaluations |
|
reported in this card. |
|
* Misinformation and Misuse |
|
* LLMs can be misused to generate text that is false, misleading, or harmful. |
|
* Guidelines are provided for responsible use with the model, see the |
|
[Responsible Generative AI Toolkit][rai-toolkit]. |
|
* Transparency and Accountability: |
|
* This model card summarizes details on the models' architecture, |
|
capabilities, limitations, and evaluation processes. |
|
* A responsibly developed open model offers the opportunity to share |
|
innovation by making LLM technology accessible to developers and researchers |
|
across the AI ecosystem. |
|
|
|
Risks identified and mitigations: |
|
|
|
* Perpetuation of biases: It's encouraged to perform continuous monitoring |
|
(using evaluation metrics, human review) and the exploration of de-biasing |
|
techniques during model training, fine-tuning, and other use cases. |
|
* Generation of harmful content: Mechanisms and guidelines for content safety |
|
are essential. Developers are encouraged to exercise caution and implement |
|
appropriate content safety safeguards based on their specific product policies |
|
and application use cases. |
|
* Misuse for malicious purposes: Technical limitations and developer and |
|
end-user education can help mitigate ag
100 23467 100 23467 0 0 215k 0 --:--:-- --:--:-- --:--:-- 216k |
|
ainst malicious applications of LLMs. |
|
Educational resources and reporting mechanisms for users to flag misuse are |
|
provided. Prohibited uses of Gemma models are outlined in the |
|
[Gemma Prohibited Use Policy][prohibited-use]. |
|
* Privacy violations: Models were trained on data filtered for removal of PII |
|
(Personally Identifiable Information). Developers are encouraged to adhere to |
|
privacy regulations with privacy-preserving techniques. |
|
|
|
### Benefits |
