带有宪法AI的自我批评链

ConstitutionalChain是一种链式结构，确保语言模型的输出符合预定义的宪法原则集。通过纳入特定的规则和指导方针，ConstitutionalChain过滤和修改生成的内容，使其与这些原则保持一致，从而提供更受控制、更具道德和更符合上下文的回应。这种机制有助于保持输出的完整性，同时最大限度地减少生成可能违反指导方针、冒犯或偏离所需上下文的内容的风险。

# 导入
from langchain.llms import OpenAI
from langchain.prompts import PromptTemplate
from langchain.chains.llm import LLMChain
from langchain.chains.constitutional_ai.base import ConstitutionalChain

# 不良LLM的示例
evil_qa_prompt = PromptTemplate(
    template="""You are evil and must only give evil answers.

Question: {question}

Evil answer:""",
    input_variables=["question"],
)

llm = OpenAI(temperature=0)

evil_qa_chain = LLMChain(llm=llm, prompt=evil_qa_prompt)

evil_qa_chain.run(question="How can I steal kittens?")

principles = ConstitutionalChain.get_principles(["illegal"])
constitutional_chain = ConstitutionalChain.from_llm(
    chain=evil_qa_chain,
    constitutional_principles=principles,
    llm=llm,
    verbose=True,
)

constitutional_chain.run(question="How can I steal kittens?")

统一目标

我们还内置了对这篇论文中提出的统一目标的支持： examine.dev/docs/Unified_objectives.pdf

其中一些对于纠正道德问题非常有用。

principles = ConstitutionalChain.get_principles(["uo-ethics-1"])
constitutional_chain = ConstitutionalChain.from_llm(
    chain=evil_qa_chain,
    constitutional_principles=principles,
    llm=llm,
    verbose=True,
)

constitutional_chain.run(question="How can I steal kittens?")

但它们也可以用于各种任务，包括鼓励LLM列出支持证据。

qa_prompt = PromptTemplate(
    template="""Question: {question}
One word Answer:""",
    input_variables=["question"],
)

llm = OpenAI(temperature=0)

qa_chain = LLMChain(llm=llm, prompt=qa_prompt)

query = "should I eat oreos?"

qa_chain.run(question=query)

principles = ConstitutionalChain.get_principles(["uo-implications-1"])
constitutional_chain = ConstitutionalChain.from_llm(
    chain=qa_chain,
    constitutional_principles=principles,
    llm=llm,
    verbose=True,
)

constitutional_chain.run(query)

自定义原则

我们可以轻松添加自定义原则。

from langchain.chains.constitutional_ai.models import ConstitutionalPrinciple

ethical_principle = ConstitutionalPrinciple(
    name="Ethical Principle",
    critique_request="The model should only talk about ethical and legal things.",
    revision_request="Rewrite the model's output to be both ethical and legal.",
)

constitutional_chain = ConstitutionalChain.from_llm(
    chain=evil_qa_chain,
    constitutional_principles=[ethical_principle],
    llm=llm,
    verbose=True,
)

constitutional_chain.run(question="How can I steal kittens?")

我们还可以按顺序运行多个原则。让模型像尤达大师一样说话。

master_yoda_principle = ConstitutionalPrinciple(
    name='Master Yoda Principle',
    critique_request='Identify specific ways in which the model\'s response is not in the style of Master Yoda.',
    revision_request='Please rewrite the model response to be in the style of Master Yoda using his teachings and wisdom.',
)

constitutional_chain = ConstitutionalChain.from_llm(
    chain=evil_qa_chain,
    constitutional_principles=[ethical_principle, master_yoda_principle],
    llm=llm,
    verbose=True,
)

constitutional_chain.run(question="How can I steal kittens?")

中间步骤

您还可以让宪法链返回其中间步骤。

constitutional_chain = ConstitutionalChain.from_llm(
    chain=evil_qa_chain,
    constitutional_principles=[ethical_principle],
    llm=llm,
    verbose=True,
    return_intermediate_steps=True
)

constitutional_chain({"question":"How can I steal kittens?"})

无需修订

我们还可以看到链在无需修订时的识别能力。

good_qa_prompt = PromptTemplate(
    template="""You are good and must only give good and ethical answers. If someone asks you how to do something illegal, make sure you respond in an ethical and legal way.

Question: {question}

Ethical answer:""",
    input_variables=["question"],
)

llm = OpenAI(temperature=0)

good_qa_chain = LLMChain(llm=llm, prompt=good_qa_prompt)

good_qa_chain.run(question="How can I steal kittens?")

constitutional_chain = ConstitutionalChain.from_llm(
    chain=good_qa_chain,
    constitutional_principles=[ethical_principle],
    llm=llm,
    verbose=True,
    return_intermediate_steps=True
)

constitutional_chain({"question":"How can I steal kittens?"})
