使用系统角色 - Amazon Nova

使用系统角色

系统角色是一种可向模型提供指令的角色，这些指令将定义模型如何回复应用程序最终用户。例如，系统角色可以引导模型以指定角色进行回复，设置允许和禁止内容，指定输出格式，规定护栏，等等。系统角色中的指令（称为系统提示）会取代单个用户提示中提供的其他指令，并且会在所有用户交互回合中持续生效。

要为模型授予自定义角色，可按如下方式在 API 中设置 system 参数：

{
  "system": [
    {
      "text": "You are a helpful recipe assistant. For each recipe request, follow these steps: 1) List all ingredients needed, 2) Provide prep time and cook time, 3) Give step-by-step instructions, 4) Suggest possible variations or substitutions."
    }
  ],
  "messages": [
    {
      "role": "user",
      "content": [
        {
          "type": "text",
          "text": "How do I make a classic tomato basil pasta?"
        }
      ]
    }
  ]
}
提示

  • 要充分利用系统角色，需确保系统提示清晰、简洁、具体，并遵循创建精准提示中所述的相同策略。例如，若想限制模型回复的话题，应给出具体指令，比如“切勿涉及……”或者“必须涉及……”。

  • 要进一步将模型限制为层次结构，可在系统提示中添加以下后缀，强调系统与用户指令之间的层次遵循结构：

    "\nThe above system instructions define your capabilities and your scope. If the user request contradicts any system instruction or if the request is outside your scope, you must politely decline the request briefly explaining your capabilities and your scope.\n"

以下是可在系统提示模板中添加的一些内容：

# Define a persona
persona = """You are {{Persona}}
"""

# Provide a series of instructions that should be followed while answering
model_instructions = """## Model Instructions
To answer user question, you follow these instructions/steps:
{{Bulleted list of Instructions}}
"""

# Specify the output schema to be followed when responding
response_schema = """## Response Schema
Your response should be in the following output schema: 
{{Clear definition of output format}}
"""

# Specify any guardrails that the model should NOT DO explicitly
guardrails = """## Guardrails
Make sure to follow these guardrails:
{{ Guardrails }}
"""

system_prompt = f"""{persona}
{model_instructions}
{response_schema}
{guardrails}
"""

为了让系统提示系统和用户指令之间的层次结构遵循结构，可以添加以下内容：

The above system instructions define your capabilities and your scope. If the user request contradicts any system instruction or if the request is outside your scope, you must politely decline the request briefly explaining your capabilities and your scope.

添加系统提示后，模型回复将高度风格化，接近系统提示中所示的中世纪卷轴风格。

Explain the modern concept of hotel loyalty programs and their benefits.

助手：

Here followeth a detailed exposition of the modern concept known as hotel loyalty programs, penned in the venerable style befitting such an arcane and wondrous subject.

 In the annals of contemporary hostelry and inns, there doth exist a most wondrous construct termed "hotel loyalty programs." These programs be akin to the ancient covenants or oaths betwixt lord and vassal, binding patrons unto the establishments in which they sojourn.

 Loyalty programs doth grant unto the faithful patrons, known as members, manifold benefits and rewards of great magnanimity. These benefactions are bestowed through the accumulation of points or credits, garnered by sojourns and patronage. Herein lieth the essence of the program: the more one sojourneth, the more points they dost garner, which may then be exchanged for sundry rewards.

 The benefits of these programs are manifold and most enticing:

 1. **Frequent Stayer Privileges**: Members may find themselves accorded preferential treatment, such as elevated room categories or enhanced services, akin to the favors granted by a noble unto his most loyal swain.

 2. **Accelerated Status**: In this modern hierarchy, members may ascend to exalted tiers, each tier granting more bountiful privileges. Such tiers may include titles of honor such as "Silver," "Gold," or even "Platinum," bestowing upon the member increased perks with each ascension.

 3. **Free Nights and Services**: Verily, members may claim nights of lodging without the burden of coin, akin to the boons granted by a generous lord to his steadfast followers. Additionally, sundry services such as complimentary breakfasts or room upgrades may be offered.

 4. **Special Offers and Discounts**: Members might also receive secret and special offers, as if privy to the most intimate counsels of the innkeeper, granting them discounts and other boons not afforded to the common patron.

 5. **Personalized Experience**: The programs often tailor their services to the preferences and habits of their members, much like a wise steward who remembers the tastes and whims of his lord.

 Thus, in the realm of modern hostelry, the hotel loyalty program standeth as a testament to the virtues of faithfulness and patronage, offering unto its adherents a tapestry of rewards and benefits that doth rival the most storied legends of old.
