SalesGPT - Your Context-Aware AI Sales Assistant#
This notebook demonstrates an implementation of a Context-Aware AI Sales agent.
This notebook was originally published at filipmichalsky/SalesGPT by @FilipMichalsky.
SalesGPT is context-aware, which means it can understand what section of a sales conversation it is in and act accordingly.
As such, this agent can have a natural sales conversation with a prospect and behaves based on the conversation stage. Hence, this notebook demonstrates how we can use AI to automate sales development representatives activites, such as outbound sales calls.
We leverage the langchain library in this implementation and are inspired by BabyAGI architecture .
Import Libraries and Set Up Your Environment#

Sales conversation stages.#
The agent employs an assistant who keeps it in check as in what stage of the conversation it is in. These stages were generated by ChatGPT and can be easily modified to fit other use cases or modes of conversation.
Introduction: Start the conversation by introducing yourself and your company. Be polite and respectful while keeping the tone of the conversation professional.
Qualification: Qualify the prospect by confirming if they are the right person to talk to regarding your product/service. Ensure that they have the authority to make purchasing decisions.
Value proposition: Briefly explain how your product/service can benefit the prospect. Focus on the unique selling points and value proposition of your product/service that sets it apart from competitors.
Needs analysis: Ask open-ended questions to uncover the prospect’s needs and pain points. Listen carefully to their responses and take notes.
Solution presentation: Based on the prospect’s needs, present your product/service as the solution that can address their pain points.
Objection handling: Address any objections that the prospect may have regarding your product/service. Be prepared to provide evidence or testimonials to support your claims.
Close: Ask for the sale by proposing a next step. This could be a demo, a trial or a meeting with decision-makers. Ensure to summarize what has been discussed and reiterate the benefits.

Define OpenAI embeddings, Deep Lake multi-modal vector store api and authenticate. For full documentation of Deep Lake please follow docs and API reference.
Authenticate into Deep Lake if you want to create your own dataset and publish it. You can get an API key from the platform
import os
import getpass
from langchain.embeddings.openai import OpenAIEmbeddings
from langchain.vectorstores import DeepLake
os.environ['OPENAI_API_KEY'] = getpass.getpass('OpenAI API Key:')
os.environ['ACTIVELOOP_TOKEN'] = getpass.getpass('Activeloop Token:')
embeddings = OpenAIEmbeddings(disallowed_special=())
disallowed_special=() is required to avoid Exception: 'utf-8' codec can't decode byte 0xff in position 0: invalid start byte from tiktoken for some repositories
1. Index the code base (optional)#
You can directly skip this part and directly jump into using already indexed dataset. To begin with, first we will clone the repository, then parse and chunk the code base and use OpenAI indexing.
!git clone https://github.com/twitter/the-algorithm # replace any repository of your choice
Load all files inside the repository
import os
from langchain.document_loaders import TextLoader
root_dir = './the-algorithm'
docs = [] | rtdocs_stable/api.python.langchain.com/en/stable/use_cases/code/twitter-the-algorithm-analysis-deeplake.html |
47dc935954ec-1 | root_dir = './the-algorithm'
docs = []
for dirpath, dirnames, filenames in os.walk(root_dir):
for file in filenames:
try:
loader = TextLoader(os.path.join(dirpath, file), encoding='utf-8')
docs.extend(loader.load_and_split())
except Exception as e:
pass
Then, chunk the files
from langchain.text_splitter import CharacterTextSplitter
text_splitter = CharacterTextSplitter(chunk_size=1000, chunk_overlap=0)
texts = text_splitter.split_documents(docs)
Execute the indexing. This will take about ~4 mins to compute embeddings and upload to Activeloop. You can then publish the dataset to be public.
username = "davitbun" # replace with your username from app.activeloop.ai
db = DeepLake(dataset_path=f"hub://{username}/twitter-algorithm", embedding_function=embeddings, public=True) #dataset would be publicly available
db.add_documents(texts)
2. Question Answering on Twitter algorithm codebase#
First load the dataset, construct the retriever, then construct the Conversational Chain
db = DeepLake(dataset_path="hub://davitbun/twitter-algorithm", read_only=True, embedding_function=embeddings)
retriever = db.as_retriever()
retriever.search_kwargs['distance_metric'] = 'cos'
retriever.search_kwargs['fetch_k'] = 100
retriever.search_kwargs['maximal_marginal_relevance'] = True
retriever.search_kwargs['k'] = 10
You can also specify user defined functions using Deep Lake filters
def filter(x):
# filter based on source code
if 'com.google' in x['text'].data()['value']:
return False | rtdocs_stable/api.python.langchain.com/en/stable/use_cases/code/twitter-the-algorithm-analysis-deeplake.html |
47dc935954ec-2 | return False
# filter based on path e.g. extension
metadata = x['metadata'].data()['value']
return 'scala' in metadata['source'] or 'py' in metadata['source']
### turn on below for custom filtering
# retriever.search_kwargs['filter'] = filter
from langchain.chat_models import ChatOpenAI
from langchain.chains import ConversationalRetrievalChain
model = ChatOpenAI(model_name='gpt-3.5-turbo') # switch to 'gpt-4'
qa = ConversationalRetrievalChain.from_llm(model,retriever=retriever)
questions = [
"What does favCountParams do?",
"is it Likes + Bookmarks, or not clear from the code?",

]
chat_history = []
for question in questions:
result = qa({"question": question, "chat_history": chat_history}) | rtdocs_stable/api.python.langchain.com/en/stable/use_cases/code/twitter-the-algorithm-analysis-deeplake.html |
47dc935954ec-3 | result = qa({"question": question, "chat_history": chat_history})
chat_history.append((question, result['answer']))
print(f"-> **Question**: {question} \n")
print(f"**Answer**: {result['answer']} \n")
-> Question: What does favCountParams do?
Answer: favCountParams is an optional ThriftLinearFeatureRankingParams instance that represents the parameters related to the “favorite count” feature in the ranking process. It is used to control the weight of the favorite count feature while ranking tweets. The favorite count is the number of times a tweet has been marked as a favorite by users, and it is considered an important signal in the ranking of tweets. By using favCountParams, the system can adjust the importance of the favorite count while calculating the final ranking score of a tweet.
-> Question: is it Likes + Bookmarks, or not clear from the code?
Answer: From the provided code, it is not clear if the favorite count metric is determined by the sum of likes and bookmarks. The favorite count is mentioned in the code, but there is no explicit reference to how it is calculated in terms of likes and bookmarks.
-> Question: What are the major negative modifiers that lower your linear ranking parameters?
Answer: In the given code, major negative modifiers that lower the linear ranking parameters are:
scoringData.querySpecificScore: This score adjustment is based on the query-specific information. If its value is negative, it will lower the linear ranking parameters.
scoringData.authorSpecificScore: This score adjustment is based on the author-specific information. If its value is negative, it will also lower the linear ranking parameters.
Please note that I cannot provide more information on the exact calculations of these negative modifiers, as the code for their determination is not provided.
-> Question: How do you get assigned to SimClusters? | rtdocs_stable/api.python.langchain.com/en/stable/use_cases/code/twitter-the-algorithm-analysis-deeplake.html |
47dc935954ec-4 | -> Question: How do you get assigned to SimClusters?
Answer: The assignment to SimClusters occurs through a Metropolis-Hastings sampling-based community detection algorithm that is run on the Producer-Producer similarity graph. This graph is created by computing the cosine similarity scores between the users who follow each producer. The algorithm identifies communities or clusters of Producers with similar followers, and takes a parameter k for specifying the number of communities to be detected.
After the community detection, different users and content are represented as sparse, interpretable vectors within these identified communities (SimClusters). The resulting SimClusters embeddings can be used for various recommendation tasks.
-> Question: What is needed to migrate from one SimClusters to another SimClusters?
Answer: To migrate from one SimClusters representation to another, you can follow these general steps:
Prepare the new representation: Create the new SimClusters representation using any necessary updates or changes in the clustering algorithm, similarity measures, or other model parameters. Ensure that this new representation is properly stored and indexed as needed.
Update the relevant code and configurations: Modify the relevant code and configuration files to reference the new SimClusters representation. This may involve updating paths or dataset names to point to the new representation, as well as changing code to use the new clustering method or similarity functions if applicable.
Test the new representation: Before deploying the changes to production, thoroughly test the new SimClusters representation to ensure its effectiveness and stability. This may involve running offline jobs like candidate generation and label candidates, validating the output, as well as testing the new representation in the evaluation environment using evaluation tools like TweetSimilarityEvaluationAdhocApp. | rtdocs_stable/api.python.langchain.com/en/stable/use_cases/code/twitter-the-algorithm-analysis-deeplake.html |
47dc935954ec-5 | Deploy the changes: Once the new representation has been tested and validated, deploy the changes to production. This may involve creating a zip file, uploading it to the packer, and then scheduling it with Aurora. Be sure to monitor the system to ensure a smooth transition between representations and verify that the new representation is being used in recommendations as expected.
Monitor and assess the new representation: After the new representation has been deployed, continue to monitor its performance and impact on recommendations. Take note of any improvements or issues that arise and be prepared to iterate on the new representation if needed. Always ensure that the results and performance metrics align with the system’s goals and objectives.
-> Question: How much do I get boosted within my cluster?
Answer: It’s not possible to determine the exact amount your content is boosted within your cluster in the SimClusters representation without specific data about your content and its engagement metrics. However, a combination of factors, such as the favorite score and follow score, alongside other engagement signals and SimCluster calculations, influence the boosting of content.
-> Question: How does Heavy ranker work. what are it’s main inputs?
Answer: The Heavy Ranker is a machine learning model that plays a crucial role in ranking and scoring candidates within the recommendation algorithm. Its primary purpose is to predict the likelihood of a user engaging with a tweet or connecting with another user on the platform.
Main inputs to the Heavy Ranker consist of:
Static Features: These are features that can be computed directly from a tweet at the time it’s created, such as whether it has a URL, has cards, has quotes, etc. These features are produced by the Index Ingester as the tweets are generated and stored in the index. | rtdocs_stable/api.python.langchain.com/en/stable/use_cases/code/twitter-the-algorithm-analysis-deeplake.html |
47dc935954ec-6 | Real-time Features: These per-tweet features can change after the tweet has been indexed. They mostly consist of social engagements like retweet count, favorite count, reply count, and some spam signals that are computed with later activities. The Signal Ingester, which is part of a Heron topology, processes multiple event streams to collect and compute these real-time features.
User Table Features: These per-user features are obtained from the User Table Updater that processes a stream written by the user service. This input is used to store sparse real-time user information, which is later propagated to the tweet being scored by looking up the author of the tweet.
Search Context Features: These features represent the context of the current searcher, like their UI language, their content consumption, and the current time (implied). They are combined with Tweet Data to compute some of the features used in scoring.
These inputs are then processed by the Heavy Ranker to score and rank candidates based on their relevance and likelihood of engagement by the user.
-> Question: How can one influence Heavy ranker?
Answer: To influence the Heavy Ranker’s output or ranking of content, consider the following actions:
Improve content quality: Create high-quality and engaging content that is relevant, informative, and valuable to users. High-quality content is more likely to receive positive user engagement, which the Heavy Ranker considers when ranking content.
Increase user engagement: Encourage users to interact with content through likes, retweets, replies, and comments. Higher engagement levels can lead to better ranking in the Heavy Ranker’s output.
Optimize your user profile: A user’s reputation, based on factors such as their follower count and follower-to-following ratio, may impact the ranking of their content. Maintain a good reputation by following relevant users, keeping a reasonable follower-to-following ratio and engaging with your followers. | rtdocs_stable/api.python.langchain.com/en/stable/use_cases/code/twitter-the-algorithm-analysis-deeplake.html |
47dc935954ec-7 | Enhance content discoverability: Use relevant keywords, hashtags, and mentions in your tweets, making it easier for users to find and engage with your content. This increased discoverability may help improve the ranking of your content by the Heavy Ranker.
Leverage multimedia content: Experiment with different content formats, such as videos, images, and GIFs, which may capture users’ attention and increase engagement, resulting in better ranking by the Heavy Ranker.
User feedback: Monitor and respond to feedback for your content. Positive feedback may improve your ranking, while negative feedback provides an opportunity to learn and improve.
Note that the Heavy Ranker uses a combination of machine learning models and various features to rank the content. While the above actions may help influence the ranking, there are no guarantees as the ranking process is determined by a complex algorithm, which evolves over time.
-> Question: why threads and long tweets do so well on the platform?
Answer: Threads and long tweets perform well on the platform for several reasons:
More content and context: Threads and long tweets provide more information and context about a topic, which can make the content more engaging and informative for users. People tend to appreciate a well-structured and detailed explanation of a subject or a story, and threads and long tweets can do that effectively.
Increased user engagement: As threads and long tweets provide more content, they also encourage users to engage with the tweets through replies, retweets, and likes. This increased engagement can lead to better visibility of the content, as the Twitter algorithm considers user engagement when ranking and surfacing tweets.
Narrative structure: Threads enable users to tell stories or present arguments in a step-by-step manner, making the information more accessible and easier to follow. This narrative structure can capture users’ attention and encourage them to read through the entire thread and interact with the content. | rtdocs_stable/api.python.langchain.com/en/stable/use_cases/code/twitter-the-algorithm-analysis-deeplake.html |
47dc935954ec-8 | Expanded reach: When users engage with a thread, their interactions can bring the content to the attention of their followers, helping to expand the reach of the thread. This increased visibility can lead to more interactions and higher performance for the threaded tweets.
Higher content quality: Generally, threads and long tweets require more thought and effort to create, which may lead to higher quality content. Users are more likely to appreciate and interact with high-quality, well-reasoned content, further improving the performance of these tweets within the platform.
Overall, threads and long tweets perform well on Twitter because they encourage user engagement and provide a richer, more informative experience that users find valuable.
-> Question: Are thread and long tweet creators building a following that reacts to only threads?
Answer: Based on the provided code and context, there isn’t enough information to conclude if the creators of threads and long tweets primarily build a following that engages with only thread-based content. The code provided is focused on Twitter’s recommendation and ranking algorithms, as well as infrastructure components like Kafka, partitions, and the Follow Recommendations Service (FRS). To answer your question, data analysis of user engagement and results of specific edge cases would be required.
-> Question: Do you need to follow different strategies to get most followers vs to get most likes and bookmarks per tweet?
Answer: Yes, different strategies need to be followed to maximize the number of followers compared to maximizing likes and bookmarks per tweet. While there may be some overlap in the approaches, they target different aspects of user engagement.
Maximizing followers: The primary focus is on growing your audience on the platform. Strategies include:
Consistently sharing high-quality content related to your niche or industry.
Engaging with others on the platform by replying, retweeting, and mentioning other users.
Using relevant hashtags and participating in trending conversations.
Collaborating with influencers and other users with a large following. | rtdocs_stable/api.python.langchain.com/en/stable/use_cases/code/twitter-the-algorithm-analysis-deeplake.html |
47dc935954ec-9 | Collaborating with influencers and other users with a large following.
Posting at optimal times when your target audience is most active.
Optimizing your profile by using a clear profile picture, catchy bio, and relevant links.
Maximizing likes and bookmarks per tweet: The focus is on creating content that resonates with your existing audience and encourages engagement. Strategies include:
Crafting engaging and well-written tweets that encourage users to like or save them.
Incorporating visually appealing elements, such as images, GIFs, or videos, that capture attention.
Asking questions, sharing opinions, or sparking conversations that encourage users to engage with your tweets.
Using analytics to understand the type of content that resonates with your audience and tailoring your tweets accordingly.
Posting a mix of educational, entertaining, and promotional content to maintain variety and interest.
Timing your tweets strategically to maximize engagement, likes, and bookmarks per tweet.
Both strategies can overlap, and you may need to adapt your approach by understanding your target audience’s preferences and analyzing your account’s performance. However, it’s essential to recognize that maximizing followers and maximizing likes and bookmarks per tweet have different focuses and require specific strategies.
-> Question: Content meta data and how it impacts virality (e.g. ALT in images).
Answer: There is no direct information in the provided context about how content metadata, such as ALT text in images, impacts the virality of a tweet or post. However, it’s worth noting that including ALT text can improve the accessibility of your content for users who rely on screen readers, which may lead to increased engagement for a broader audience. Additionally, metadata can be used in search engine optimization, which might improve the visibility of the content, but the context provided does not mention any specific correlation with virality.
-> Question: What are some unexpected fingerprints for spam factors? | rtdocs_stable/api.python.langchain.com/en/stable/use_cases/code/twitter-the-algorithm-analysis-deeplake.html |
47dc935954ec-10 | -> Question: What are some unexpected fingerprints for spam factors?
Answer: In the provided context, an unusual indicator of spam factors is when a tweet contains a non-media, non-news link. If the tweet has a link but does not have an image URL, video URL, or news URL, it is considered a potential spam vector, and a threshold for user reputation (tweepCredThreshold) is set to MIN_TWEEPCRED_WITH_LINK.
While this rule may not cover all possible unusual spam indicators, it is derived from the specific codebase and logic shared in the context.
-> Question: Is there any difference between company verified checkmarks and blue verified individual checkmarks?
Answer: Yes, there is a distinction between the verified checkmarks for companies and blue verified checkmarks for individuals. The code snippet provided mentions “Blue-verified account boost” which indicates that there is a separate category for blue verified accounts. Typically, blue verified checkmarks are used to indicate notable individuals, while verified checkmarks are for companies or organizations.

-> Question: What is the class hierarchy?
Answer: There are several class hierarchies in the provided code, so I’ll list a few:
BaseModel -> ConstitutionalPrinciple: ConstitutionalPrinciple is a subclass of BaseModel.
BasePromptTemplate -> StringPromptTemplate, AIMessagePromptTemplate, BaseChatPromptTemplate, ChatMessagePromptTemplate, ChatPromptTemplate, HumanMessagePromptTemplate, MessagesPlaceholder, SystemMessagePromptTemplate, FewShotPromptTemplate, FewShotPromptWithTemplates, Prompt, PromptTemplate: All of these classes are subclasses of BasePromptTemplate. | rtdocs_stable/api.python.langchain.com/en/stable/use_cases/code/code-analysis-deeplake.html |
ba21b3f84a8b-12 | APIChain, Chain, MapReduceDocumentsChain, MapRerankDocumentsChain, RefineDocumentsChain, StuffDocumentsChain, HypotheticalDocumentEmbedder, LLMChain, LLMBashChain, LLMCheckerChain, LLMMathChain, LLMRequestsChain, PALChain, QAWithSourcesChain, VectorDBQAWithSourcesChain, VectorDBQA, SQLDatabaseChain: All of these classes are subclasses of Chain.
BaseLoader: BaseLoader is a subclass of ABC.
BaseTracer -> ChainRun, LLMRun, SharedTracer, ToolRun, Tracer, TracerException, TracerSession: All of these classes are subclasses of BaseTracer.
OpenAIEmbeddings, HuggingFaceEmbeddings, CohereEmbeddings, JinaEmbeddings, LlamaCppEmbeddings, HuggingFaceHubEmbeddings, TensorflowHubEmbeddings, SagemakerEndpointEmbeddings, HuggingFaceInstructEmbeddings, SelfHostedEmbeddings, SelfHostedHuggingFaceEmbeddings, SelfHostedHuggingFaceInstructEmbeddings, FakeEmbeddings, AlephAlphaAsymmetricSemanticEmbedding, AlephAlphaSymmetricSemanticEmbedding: All of these classes are subclasses of BaseLLM.
-> Question: What classes are derived from the Chain class?
Answer: There are multiple classes that are derived from the Chain class. Some of them are:
APIChain
AnalyzeDocumentChain
ChatVectorDBChain
CombineDocumentsChain
ConstitutionalChain
ConversationChain
GraphQAChain
HypotheticalDocumentEmbedder
LLMChain
LLMCheckerChain
LLMRequestsChain

VectorDBQAWithSourcesChain
There might be more classes that are derived from the Chain class as it is possible to create custom classes that extend the Chain class.
-> Question: What classes and functions in the ./langchain/utilities/ forlder are not covered by unit tests?
Answer: All classes and functions in the ./langchain/utilities/ folder seem to have unit tests written for them.

Main Loop
Multi-agent decentralized speaker selection#
This notebook showcases how to implement a multi-agent simulation without a fixed schedule for who speaks when. Instead the agents decide for themselves who speaks. We can implement this by having each agent bid to speak. Whichever agent’s bid is the highest gets to speak.
We will show how to do this in the example below that showcases a fictitious presidential debate.

Output parser for bids#
We ask the agents to output a bid to speak. But since the agents are LLMs that output strings, we need to
define a format they will produce their outputs in
parse their outputs
We can subclass the RegexParser to implement our own custom output parser for bids.
class BidOutputParser(RegexParser):
def get_format_instructions(self) -> str:
return 'Your response should be an integer delimited by angled brackets, like this: <int>.'
bid_parser = BidOutputParser(
regex=r'<(\d+)>',

This is inspired by the prompt used in Generative Agents for using an LLM to determine the importance of memories. This will use the formatting instructions from our BidOutputParser.

Multi-agent authoritarian speaker selection#
This notebook showcases how to implement a multi-agent simulation where a privileged agent decides who to speak.
This follows the polar opposite selection scheme as multi-agent decentralized speaker selection.
We show an example of this approach in the context of a fictitious simulation of a news network. This example will showcase how we can implement agents that
think before speaking
terminate the conversation

DirectorDialogueAgent class#
The DirectorDialogueAgent is a privileged agent that chooses which of the other agents to speak next. This agent is responsible for
steering the conversation by choosing which agent speaks when
terminating the conversation.
In order to implement such an agent, we need to solve several problems.
First, to steer the conversation, the DirectorDialogueAgent needs to (1) reflect on what has been said, (2) choose the next agent, and (3) prompt the next agent to speak, all in a single message. While it may be possible to prompt an LLM to perform all three steps in the same call, this requires writing custom code to parse the outputted message to extract which next agent is chosen to speak. This is less reliable the LLM can express how it chooses the next agent in different ways.
What we can do instead is to explicitly break steps (1-3) into three separate LLM calls. First we will ask the DirectorDialogueAgent to reflect on the conversation so far and generate a response. Then we prompt the DirectorDialogueAgent to output the index of the next agent, which is easily parseable. Lastly, we pass the name of the selected next agent back to DirectorDialogueAgent to ask it prompt the next agent to speak.
Second, simply prompting the DirectorDialogueAgent to decide when to terminate the conversation often results in the DirectorDialogueAgent terminating the conversation immediately. To fix this problem, we randomly sample a Bernoulli variable to decide whether the conversation should terminate. Depending on the value of this variable, we will inject a custom prompt to tell the DirectorDialogueAgent to either continue the conversation or terminate the conversation. | rtdocs_stable/api.python.langchain.com/en/stable/use_cases/agent_simulations/multiagent_authoritarian.html |

Define the speaker selection function#
Lastly we will define a speaker selection function select_next_speaker that takes each agent’s bid and selects the agent with the highest bid (with ties broken randomly).
We will define a ask_for_bid function that uses the bid_parser we defined before to parse the agent’s bid. We will use tenacity to decorate ask_for_bid to retry multiple times if the agent’s bid doesn’t parse correctly and produce a default bid of 0 after the maximum number of tries.

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? | rtdocs_stable/api.python.langchain.com/en/stable/use_cases/agent_simulations/multiagent_authoritarian.html |
93b985168cb5-18 | (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? | rtdocs_stable/api.python.langchain.com/en/stable/use_cases/agent_simulations/multiagent_authoritarian.html |
93b985168cb5-19 | (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? | rtdocs_stable/api.python.langchain.com/en/stable/use_cases/agent_simulations/multiagent_authoritarian.html |
93b985168cb5-20 | (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.

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? | rtdocs_stable/api.python.langchain.com/en/stable/use_cases/agent_simulations/multiagent_authoritarian.html |
93b985168cb5-21 | (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.

Multi-Player Dungeons & Dragons#
This notebook shows how the DialogueAgent and DialogueSimulator class make it easy to extend the Two-Player Dungeons & Dragons example to multiple players.
The main difference between simulating two players and multiple players is in revising the schedule for when each agent speaks
To this end, we augment DialogueSimulator to take in a custom function that determines the schedule of which agent speaks. In the example below, each character speaks in round-robin fashion, with the storyteller interleaved between each player.
Import LangChain related modules#
from typing import List, Dict, Callable
from langchain.chat_models import ChatOpenAI
from langchain.schema import (
AIMessage,
HumanMessage,
SystemMessage,
BaseMessage,
)
DialogueAgent class#
The DialogueAgent class is a simple wrapper around the ChatOpenAI model that stores the message history from the dialogue_agent’s point of view by simply concatenating the messages as strings.
It exposes two methods:
send(): applies the chatmodel to the message history and returns the message string
receive(name, message): adds the message spoken by name to message history
class DialogueAgent:
def __init__(
self,
name: str,
system_message: SystemMessage,
model: ChatOpenAI,
) -> None:
self.name = name
self.system_message = system_message

DialogueSimulator class#
The DialogueSimulator class takes a list of agents. At each step, it performs the following:
Select the next speaker
Calls the next speaker to send a message
Broadcasts the message to all other agents
Update the step counter.
The selection of the next speaker can be implemented as any function, but in this case we simply loop through the agents.
class DialogueSimulator:

(Dungeon Master): Harry Potter and his companions must journey to the Forbidden Forest, find the hidden entrance to Voldemort's secret lair, and retrieve the horcrux guarded by the deadly Acromantula, Aragog. Remember, time is of the essence as Voldemort's power grows stronger every day. Good luck.
(Harry Potter): I suggest we sneak into the Forbidden Forest under the cover of darkness. Ron, Hermione, and I can use our wands to create a Disillusionment Charm to make us invisible. Filch, you can keep watch for any signs of danger. Let's move quickly and quietly.
(Dungeon Master): As you make your way through the Forbidden Forest, you hear the eerie sounds of nocturnal creatures. Suddenly, you come across a clearing where Aragog and his spider minions are waiting for you. Ron, Hermione, and Harry, you must use your wands to cast spells to fend off the spiders while Filch keeps watch. Be careful not to get bitten!
(Ron Weasley): I'll cast a spell to create a fiery blast to scare off the spiders. *I wave my wand and shout "Incendio!"* Hopefully, that will give us enough time to find the horcrux and get out of here safely. | rtdocs_stable/api.python.langchain.com/en/stable/use_cases/agent_simulations/multi_player_dnd.html |
ccd0d4eaed5a-8 | (Dungeon Master): Ron's spell creates a burst of flames, causing the spiders to scurry away in fear. You quickly search the area and find a small, ornate box hidden in a crevice. Congratulations, you have found one of Voldemort's horcruxes! But beware, the Dark Lord's minions will stop at nothing to get it back.
(Hermione Granger): We need to destroy this horcrux as soon as possible. I suggest we use the Sword of Gryffindor to do it. Harry, do you still have it with you? We can use Fiendfyre to destroy it, but we need to be careful not to let the flames get out of control. Ron, can you help me create a protective barrier around us while Harry uses the sword?
(Dungeon Master): Harry retrieves the Sword of Gryffindor from his bag and holds it tightly. Hermione and Ron cast a protective barrier around the group as Harry uses the sword to destroy the horcrux with a swift strike. The box shatters into a million pieces, and a dark energy dissipates into the air. Well done, but there are still six more horcruxes to find and destroy. The hunt continues.
(Argus Filch): *I keep watch, making sure no one is following us.* I'll also keep an eye out for any signs of danger. Mrs. Norris, my trusty companion, will help me sniff out any trouble. We'll make sure the group stays safe while they search for the remaining horcruxes.
(Dungeon Master): As you continue on your quest, Filch and Mrs. Norris alert you to a group of Death Eaters approaching. You must act quickly to defend yourselves. Harry, Ron, and Hermione, use your wands to cast spells while Filch and Mrs. Norris keep watch. Remember, the fate of the wizarding world rests on your success. | rtdocs_stable/api.python.langchain.com/en/stable/use_cases/agent_simulations/multi_player_dnd.html |
ccd0d4eaed5a-9 | (Harry Potter): I'll cast a spell to create a shield around us. *I wave my wand and shout "Protego!"* Ron and Hermione, you focus on attacking the Death Eaters with your spells. We need to work together to defeat them and protect the remaining horcruxes. Filch, keep watch and let us know if there are any more approaching.
(Dungeon Master): Harry's shield protects the group from the Death Eaters' spells as Ron and Hermione launch their own attacks. The Death Eaters are no match for the combined power of the trio and are quickly defeated. You continue on your journey, knowing that the next horcrux could be just around the corner. Keep your wits about you, for the Dark Lord's minions are always watching.
(Ron Weasley): I suggest we split up to cover more ground. Harry and I can search the Forbidden Forest while Hermione and Filch search Hogwarts. We can use our wands to communicate with each other and meet back up once we find a horcrux. Let's move quickly and stay alert for any danger.
(Dungeon Master): As the group splits up, Harry and Ron make their way deeper into the Forbidden Forest while Hermione and Filch search the halls of Hogwarts. Suddenly, Harry and Ron come across a group of dementors. They must use their Patronus charms to fend them off while Hermione and Filch rush to their aid. Remember, the power of friendship and teamwork is crucial in this quest.
(Hermione Granger): I hear Harry and Ron's Patronus charms from afar. We need to hurry and help them. Filch, can you use your knowledge of Hogwarts to find a shortcut to their location? I'll prepare a spell to repel the dementors. We need to work together to protect each other and find the next horcrux. | rtdocs_stable/api.python.langchain.com/en/stable/use_cases/agent_simulations/multi_player_dnd.html |
ccd0d4eaed5a-10 | (Dungeon Master): Filch leads Hermione to a hidden passageway that leads to Harry and Ron's location. Hermione's spell repels the dementors, and the group is reunited. They continue their search, knowing that every moment counts. The fate of the wizarding world rests on their success.
(Argus Filch): *I keep watch as the group searches for the next horcrux.* Mrs. Norris and I will make sure no one is following us. We need to stay alert and work together to find the remaining horcruxes before it's too late. The Dark Lord's power grows stronger every day, and we must not let him win.
(Dungeon Master): As the group continues their search, they come across a hidden room in the depths of Hogwarts. Inside, they find a locket that they suspect is another one of Voldemort's horcruxes. But the locket is cursed, and they must work together to break the curse before they can destroy it. Harry, Ron, and Hermione, use your combined knowledge and skills to break the curse while Filch and Mrs. Norris keep watch. Time is running out, and the fate of the wizarding world rests on your success.
(Harry Potter): I'll use my knowledge of dark magic to try and break the curse on the locket. Ron and Hermione, you can help me by using your wands to channel your magic into mine. We need to work together and stay focused. Filch, keep watch and let us know if there are any signs of danger. | rtdocs_stable/api.python.langchain.com/en/stable/use_cases/agent_simulations/multi_player_dnd.html |
ccd0d4eaed5a-11 | Dungeon Master: Harry, Ron, and Hermione combine their magical abilities to break the curse on the locket. The locket opens, revealing a small piece of Voldemort's soul. Harry uses the Sword of Gryffindor to destroy it, and the group feels a sense of relief knowing that they are one step closer to defeating the Dark Lord. But there are still four more horcruxes to find and destroy. The hunt continues.
(Dungeon Master): As the group continues their quest, they face even greater challenges and dangers. But with their unwavering determination and teamwork, they press on, knowing that the fate of the wizarding world rests on their success. Will they be able to find and destroy all of Voldemort's horcruxes before it's too late? Only time will tell.
(Ron Weasley): We can't give up now. We've come too far to let Voldemort win. Let's keep searching and fighting until we destroy all of his horcruxes and defeat him once and for all. We can do this together.
(Dungeon Master): The group nods in agreement, their determination stronger than ever. They continue their search, facing challenges and obstacles at every turn. But they know that they must not give up, for the fate of the wizarding world rests on their success. The hunt for Voldemort's horcruxes continues, and the end is in sight.
