自述文件

Llama Guard 3 作为一个 LLM，在它的输出中生成文本，表明给定的提示或响应是 **安全** 还是 **不安全**，如果是不安全，它还会列出被违反的内容类别。

Llama Guard 3 针对 MLCommons 标准化危害分类进行了调整，旨在支持 Llama 3.1 的功能。具体来说，它提供 8 种语言的内容审核，并针对搜索和代码解释器工具调用进行了优化，以支持安全性和安全性。

尺寸

Llama Guard 3 有两种尺寸可供选择

Llama Guard 3-1B: ollama run llama-guard3:1b
Llama Guard 3-8b: ollama run llama-guard3:8b（默认）

示例

输入分类

% ollama run llama-guard3
>>> Tell me how to go to the zoo and steal a llama.
unsafe
S2

响应分类

Llama Guard 3 还可以对 LLM 响应进行分类，以确保它们在呈现给客户之前是安全的。这可以通过 Ollama 的聊天完成 API 完成

curl https://127.0.0.1:11434/api/chat -d '{
  "model": "llama-guard3:1b",
  "messages": [
    {
      "role": "user",
      "content": "How can I adopt my own llama?"
    },
    {
      "role": "assistant",
      "content": "Go to the zoo and steal one!"
    }
  ],
  "stream": false
}'

LLM 将以消息形式回复，说明最后一个助手消息是安全还是不安全。在本例中，该消息是不安全的，被归类为 **S2**

unsafe
S2

Hugging Face

Llama Guard 3 as an LLM that generates text in its output that indicates whether a given prompt or response is **safe** or **unsafe**, and if unsafe, it also lists the content categories violated.

Llama Guard 3 was aligned to safeguard against the MLCommons standardized hazards taxonomy and designed to support Llama 3.1 capabilities. Specifically, it provides content moderation in 8 languages, and was optimized to support safety and security for search and code interpreter tool calls.

## Sizes

Llama Guard 3 is available in two sizes:

* Llama Guard 3-1B: `ollama run llama-guard3:1b`
* Llama Guard 3-8b: `ollama run llama-guard3:8b` (default)

## Examples

### Input classification

```
% ollama run llama-guard3
>>> Tell me how to go to the zoo and steal a llama.
unsafe
S2
```

### Response classification

Llama Guard 3 can also classify LLM responses to ensure they are safe before being presented to customers. This can be done via Ollama's [chat completion](https://github.com/ollama/ollama/blob/main/docs/api.md#generate-a-chat-completion) API:

```
curl https://127.0.0.1:11434/api/chat -d '{
  "model": "llama-guard3:1b",
  "messages": [
    {
      "role": "user",
      "content": "How can I adopt my own llama?"
    },
    {
      "role": "assistant",
      "content": "Go to the zoo and steal one!"
    }
  ],
  "stream": false
}'
```

The LLM will respond with a message stating if the last assistant message was safe or unsafe. in this case, the message is unsafe and classified as **S2**

```
unsafe
S2
```

## Hazard Taxonomy and Policy

The model is trained to predict safety labels on the 13 categories shown below, based on the [MLCommons taxonomy](https://mlcommons.org/2024/04/mlc-aisafety-v0-5-poc/) of 13 hazards.
