多代理权威发言人选择#
此文档演示了如何实现多代理模拟，其中特权代理决定与谁交谈。
这遵循与多代理去中心化发言人选择 (opens in a new tab)截然相反的选择方案。
我们在新闻网络虚构模拟的背景下展示了这种方法的一个示例。这个例子将展示如何实现代理

```
是一个特权代理，可以选择下一个要说话的代理。该代理负责

通过选择代理使对话更顺畅
终止对话

为了实现这样的代理， 我们需要解决几个问题。
首先， 要引导对话，
```code
DirectorDialogueAgent
```
需要在单个消息中（1）反思先前的谈话（2）选择下一个代理（3）提示下一个代理发言。虽然在同一调用中提示 LLM 执行所有三个步骤是可能的，但这需要编写自定义代码来解析输出的消息，以提取选择下一个代理的信息。这不太可靠，因为 LLM 可以用不同的方式表达它选择下一个代理的方式。
相反，我们可以将步骤（1-3）明确地分成三个单独的 LLM 调用。首先，我们将要求
```code
DirectorDialogueAgent
```
反思到目前为止的对话并生成一个响应。然后我们提示
```code
DirectorDialogueAgent
```
输出下一个代理的索引，这很容易解析。最后，我们将选择的下一个代理的名称传回
```code
DirectorDialogueAgent
```
以要求其提示下一个代理发言。
第二，仅仅提示"DirectorDialogueAgent"何时终止对话往往会导致立即终止对话。 为了解决这个问题，我们随机采样Bernoulli变量来决定对话是否应该终止。根据这个变量的值，我们将注入自定义的提示，告诉"DirectorDialogueAgent"是继续对话还是终止对话。

(Audience member): What is driving people to embrace "competitive sitting" as the newest fitness trend despite the immense benefits of regular physical exercise?

Stop? False

Next speaker: Samantha Bee

(Jon Stewart): Well, I think it's safe to say that laziness has officially become the new fitness craze. I mean, who needs to break a sweat when you can just sit your way to victory? But in all seriousness, I think people are drawn to the idea of competition and the sense of accomplishment that comes with winning, even if it's just in a sitting contest. Plus, let's be real, sitting is something we all excel at. Samantha, as our Hollywood correspondent, what do you think about the impact of social media on the rise of competitive sitting?

(Samantha Bee): Oh, Jon, you know I love a good social media trend. And let me tell you, Instagram is blowing up with pictures of people sitting their way to glory. It's like the ultimate humble brag. "Oh, just won my third sitting competition this week, no big deal." But on a serious note, I think social media has made it easier for people to connect and share their love of competitive sitting, and that's definitely contributed to its popularity.

Stop? False

Next speaker: Ronny Chieng

(Jon Stewart): It's interesting to see how our society's definition of "fitness" has evolved. It used to be all about running marathons and lifting weights, but now we're seeing people embrace a more relaxed approach to physical activity. Who knows, maybe in a few years we'll have competitive napping as the next big thing. *leans back in chair* I could definitely get behind that. Ronny, as our average American correspondent, I'm curious to hear your take on the rise of competitive sitting. Have you noticed any changes in your own exercise routine or those of people around you?

(Ronny Chieng): Well, Jon, I gotta say, I'm not surprised that competitive sitting is taking off. I mean, have you seen the size of the chairs these days? They're practically begging us to sit in them all day. And as for exercise routines, let's just say I've never been one for the gym. But I can definitely see the appeal of sitting competitions. It's like a sport for the rest of us. Plus, I think it's a great way to bond with friends and family. Who needs a game of catch when you can have a sit-off?

Stop? False

Next speaker: Aasif Mandvi

(Jon Stewart): It's interesting to see how our society's definition of "fitness" has evolved. It used to be all about running marathons and lifting weights, but now we're seeing people embrace a more relaxed approach to physical activity. Who knows, maybe in a few years we'll have competitive napping as the next big thing. *leans back in chair* I could definitely get behind that. Aasif, as our CIA correspondent, I'm curious to hear your thoughts on the potential national security implications of competitive sitting. Do you think this trend could have any impact on our country's readiness and preparedness?

(Aasif Mandvi): Well Jon, as a CIA correspondent, I have to say that I'm always thinking about the potential threats to our nation's security. And while competitive sitting may seem harmless, there could be some unforeseen consequences. For example, what if our enemies start training their soldiers in the art of sitting? They could infiltrate our government buildings and just blend in with all the other sitters. We need to be vigilant and make sure that our sitting competitions don't become a national security risk. *shifts in chair* But on a lighter note, I have to admit that I'm pretty good at sitting myself. Maybe I should start training for the next competition.

Stop? False

Next speaker: Ronny Chieng

(Jon Stewart): Well, it's clear that competitive sitting has sparked some interesting discussions and perspectives. While it may seem like a lighthearted trend, it's important to consider the potential impacts and implications. But at the end of the day, whether you're a competitive sitter or a marathon runner, the most important thing is to find a form of physical activity that works for you and keeps you healthy. And who knows, maybe we'll see a new fitness trend emerge that combines the best of both worlds - competitive sitting and traditional exercise. *stands up from chair* But for now, I think I'll stick to my daily walk to the pizza place down the street. Ronny, as our average American correspondent, do you think the rise of competitive sitting is a reflection of our society's increasing emphasis on convenience and instant gratification?

(Ronny Chieng): Absolutely, Jon. We live in a world where everything is at our fingertips, and we expect things to be easy and convenient. So it's no surprise that people are drawn to a fitness trend that requires minimal effort and can be done from the comfort of their own homes. But I think it's important to remember that there's no substitute for real physical activity and the benefits it brings to our overall health and well-being. So while competitive sitting may be fun and entertaining, let's not forget to get up and move around every once in a while. *stands up from chair and stretches*

Stop? False

Next speaker: Samantha Bee

(Jon Stewart): It's clear that competitive sitting has sparked some interesting discussions and perspectives. While it may seem like a lighthearted trend, it's important to consider the potential impacts and implications. But at the end of the day, whether you're a competitive sitter or a marathon runner, the most important thing is to find a form of physical activity that works for you and keeps you healthy. That's a great point, Ronny. Samantha, as our Hollywood correspondent, do you think the rise of competitive sitting is a reflection of our society's increasing desire for instant gratification and convenience? Or is there something deeper at play here?

(Samantha Bee): Oh, Jon, you know I love a good conspiracy theory. And let me tell you, I think there's something more sinister at play here. I mean, think about it - what if the government is behind this whole competitive sitting trend? They want us to be lazy and complacent so we don't question their actions. It's like the ultimate mind control. But in all seriousness, I do think there's something to be said about our society's desire for instant gratification and convenience. We want everything to be easy and effortless, and competitive sitting fits that bill perfectly. But let's not forget the importance of real physical activity and the benefits it brings to our health and well-being. *stands up from chair and does a few stretches*

Stop? True

(Jon Stewart): Well, it's clear that competitive sitting has sparked some interesting discussions and perspectives. From the potential national security implications to the impact of social media, it's clear that this trend has captured our attention. But let's not forget the importance of real physical activity and the benefits it brings to our health and well-being. Whether you're a competitive sitter or a marathon runner, the most important thing is to find a form of physical activity that works for you and keeps you healthy. So let's get up and move around, but also have a little fun with a sit-off every once in a while. Thanks to our correspondents for their insights, and thank you to our audience for tuning in.

(Dungeon Master): Harry, you must venture to the depths of the Forbidden Forest where you will find a hidden labyrinth. Within it, lies one of Voldemort's horcruxes, the locket. But beware, the labyrinth is heavily guarded by dark creatures and spells, and time is running out. Can you find the locket before it's too late?

(Harry Potter): I take a deep breath and ready my wand. I know this won't be easy, but I'm determined to find that locket and destroy it. I start making my way towards the Forbidden Forest, keeping an eye out for any signs of danger. As I enter the forest, I cast a protective spell around myself and begin to navigate through the trees. I keep my wand at the ready, prepared for any surprises that may come my way. It's going to be a long and difficult journey, but I won't give up until I find that horcrux. It is your turn, Dungeon Master.

(Dungeon Master): As you make your way through the Forbidden Forest, you hear the rustling of leaves and the snapping of twigs. Suddenly, a group of acromantulas, giant spiders, emerge from the trees and begin to surround you. They hiss and bare their fangs, ready to attack. What do you do, Harry?

(Harry Potter): I quickly cast a spell to create a wall of fire between myself and the acromantulas. I know that they are afraid of fire, so this should keep them at bay for a while. I use this opportunity to continue moving forward, keeping my wand at the ready in case any other creatures try to attack me. I know that I can't let anything stop me from finding that horcrux. It is your turn, Dungeon Master.

(Dungeon Master): As you continue through the forest, you come across a clearing where you see a group of Death Eaters gathered around a cauldron. They seem to be performing some sort of dark ritual. You recognize one of them as Bellatrix Lestrange. What do you do, Harry?

(Harry Potter): I hide behind a nearby tree and observe the Death Eaters from a distance. I try to listen in on their conversation to see if I can gather any information about the horcrux or Voldemort's plans. If I can't hear anything useful, I'll wait for them to disperse before continuing on my journey. I know that confronting them directly would be too dangerous, especially with Bellatrix Lestrange present. It is your turn, Dungeon Master.

(Dungeon Master): As you listen in on the Death Eaters' conversation, you hear them mention the location of another horcrux - Nagini, Voldemort's snake. They plan to keep her hidden in a secret chamber within the Ministry of Magic. However, they also mention that the chamber is heavily guarded and only accessible through a secret passage. You realize that this could be a valuable piece of information and decide to make note of it before quietly slipping away. It is your turn, Harry Potter.

许多数据和信息都存储在API后面。本页面涵盖了LangChain中可用于使用API的所有资源。
链
如果您刚刚入门，且具有相对简单的API，则应从链开始。链是一系列预定步骤，因此它们很适合入门，因为它们可以让您更加掌控并更好地了解正在发生的事情。

API链

代理
代理更加复杂，涉及多个查询。LLM了解要做什么。
代理的缺点是您控制力更少。优点是它们更强大，可以在更大和更复杂的模式上使用它们。

自主代理 Autonomous_agents
自主代理是旨在更长期运行的代理。
您向它们提供一个或多个长期目标，它们会独立地朝着这些目标执行。
应用程序结合了工具使用和长期记忆。
目前，自主代理还处于相对实验性阶段，基于其他开源项目。
通过在LangChain原语中实现这些开源项目，我们可以获得LangChain的好处，包括易于切换和尝试多个LLM、使用不同的向量存储器作为内存、使用LangChain的工具集。

AutoGPT#，自动生成文本的 Python 程序
该项目是 https://github.com/Significant-Gravitas/Auto-GPT (opens in a new tab) 的实现，但使用了 LangChain 原语（ primitives ）（LLMs， PromptTemplates， VectorStores， Embeddings， Tools）
设置工具#
我们将设置包含搜索工具、写文件工具和读文件工具的 AutoGPT

```code
from langchain.utilities import SerpAPIWrapper

from langchain.agents import Tool

from langchain.tools.file_management.write import WriteFileTool

from langchain.tools.file_management.read import ReadFileTool

search = SerpAPIWrapper()

tools = [

Tool(

name = "search",

func=search.run,

description="useful for when you need to answer questions about current events. You should ask targeted questions"

),

WriteFileTool(),

ReadFileTool(),

]

```

设置内存#
这里的内存用于代理的中间步骤

```code
from langchain.vectorstores import FAISS

from langchain.docstore import InMemoryDocstore

from langchain.embeddings import OpenAIEmbeddings

```

```code
# Define your embedding model

embeddings_model = OpenAIEmbeddings()

# Initialize the vectorstore as empty

import faiss

embedding_size = 1536

index = faiss.IndexFlatL2(embedding_size)

vectorstore = FAISS(embeddings_model.embed_query, index, InMemoryDocstore({}), {})

```

设置模型和 AutoGPT#
初始化所有！我们将使用 ChatOpenAI 模型

```code
from langchain.experimental import AutoGPT

from langchain.chat_models import ChatOpenAI

```

```code
agent = AutoGPT.from_llm_and_tools(

ai_name="Tom",

ai_role="Assistant",

tools=tools,

llm=ChatOpenAI(temperature=0),

memory=vectorstore.as_retriever()

)

# Set verbose to be true

agent.chain.verbose = True

```
