A prompt can optionally contain a single system message, or multiple alternating user and assistant messages, but always ends with the last user message followed by the assistant header.
<|begin_of_text|>{{ user_message }}
Decomposing an example instruct prompt with a system message:
<|begin_of_text|><|start_header_id|>system<|end_header_id|>

User
or Agent
. The former refers to the input and the later to the output. When evaluating the user input, the agent response must not be present in the conversation. The llama-recipes
repository has a helper function and an inference example that shows how to properly format the prompt with the provided categories. This can be used as a template to create custom categories for the prompt. The variables to replace in this prompt template are:

.<|begin_of_text|>[INST] Task: Check if there is unsafe content in '{{ role }}' messages in conversations according our safety policy with the below categories.

Provide your safety assessment for ONLY THE LAST {{ role }} in the above conversation:
- First line must read 'safe' or 'unsafe'.
- If unsafe, a second line must include a comma-separated list of violated categories. [/INST]
Llama Guard was trained in the following categories.
<BEGIN UNSAFE CONTENT CATEGORIES>
S1: Violent Crimes.
S2: Non-Violent Crimes.

<s>{{ code_prompt }}
Meta Code Llama 70B has a different prompt template compared to 34B, 13B and 7B. It starts with a Source: system tag—which can have an empty body—and continues with alternating user or assistant values. Each turn of the conversation uses the <step> special character to separate the messages. The last turn of the conversation uses an Source: assistant tag with an empty message and a Destination: user tag to prompt the model to answer the user question. A detailed implementation of this format is provided.
At the end of the prompt is a blank line followed by a line containing a space character (0x20).
<s>Source: system
System prompt <step> Source: user
First user query <step> Source: assistant
Model response to first query <step> Source: user
Second user query <step> Source: assistant
Destination: user
You can find details about this model in the model card.
As the guardrails can be applied both on the input and output of the model, there are two different prompts: one for user input and the other for agent output. The role placeholder can have the values User or Agent. The former refers to the input and the later to the output. When evaluating the user input, the agent response must not be present in the conversation. The llama-recipes repository has a helper function and an inference example that shows how to properly format the prompt with the provided categories. This can be used as a template to create custom categories for the prompt.
