Conversational Retriever Chain
Code Understanding#
Overview
LangChain is a useful tool designed to parse GitHub code repositories. By leveraging VectorStores, Conversational RetrieverChain, and GPT-4, it can answer questions in the context of an entire GitHub repository or generate new code. This documentation page outlines the essential components of the system and guides using LangChain for better code comprehension, contextual question answering, and code generation in GitHub repositories.
Conversational Retriever Chain#
Conversational RetrieverChain is a retrieval-focused system that interacts with the data stored in a VectorStore. Utilizing advanced techniques, like context-aware filtering and ranking, it retrieves the most relevant code snippets and information for a given user query. Conversational RetrieverChain is engineered to deliver high-quality, pertinent results while considering conversation history and context.
LangChain Workflow for Code Understanding and Generation
Index the code base: Clone the target repository, load all files within, chunk the files, and execute the indexing process. Optionally, you can skip this step and use an already indexed dataset.
Embedding and Code Store: Code snippets are embedded using a code-aware embedding model and stored in a VectorStore.
Query Understanding: GPT-4 processes user queries, grasping the context and extracting relevant details.
Construct the Retriever: Conversational RetrieverChain searches the VectorStore to identify the most relevant code snippets for a given query.
Build the Conversational Chain: Customize the retriever settings and define any user-defined filters as needed.
Ask questions: Define a list of questions to ask about the codebase, and then use the ConversationalRetrievalChain to generate context-aware answers. The LLM (GPT-4) generates comprehensive, context-aware answers based on retrieved code snippets and conversation history.

Summarization
Summarization#
Conceptual Guide
Summarization involves creating a smaller summary of multiple longer documents.
This can be useful for distilling long documents into the core pieces of information.
The recommended way to get started using a summarization chain is:
from langchain.chains.summarize import load_summarize_chain
chain = load_summarize_chain(llm, chain_type="map_reduce")
chain.run(docs)
The following resources exist:

Utilities for working with Documents: Guides on how to use several of the utilities which will prove helpful for this task, including Text Splitters (for splitting up long documents).

Querying Tabular Data#
Conceptual Guide
Lots of data and information is stored in tabular data, whether it be csvs, excel sheets, or SQL tables.
This page covers all resources available in LangChain for working with data in this format.
Document Loading#
If you have text data stored in a tabular format, you may want to load the data into a Document and then index it as you would
other text/unstructured data. For this, you should use a document loader like the CSVLoader
and then you should create an index over that data, and query it that way.
Querying#
If you have more numeric tabular data, or have a large amount of data and don’t want to index it, you should get started
by looking at various chains and agents we have for dealing with this data.
Chains#
If you are just getting started, and you have relatively small/simple tabular data, you should get started with chains.
Chains are a sequence of predetermined steps, so they are good to get started with as they give you more control and let you
understand what is happening better.
SQL Database Chain
Agents#
Agents are more complex, and involve multiple queries to the LLM to understand what to do.
The downside of agents are that you have less control. The upside is that they are more powerful,
which allows you to use them on larger databases and more complex schemas.

AutoGPT#
Implementation of https://github.com/Significant-Gravitas/Auto-GPT but with LangChain primitives (LLMs, PromptTemplates, VectorStores, Embeddings, Tools)
Set up tools#
We’ll set up an AutoGPT with a search tool, and write-file tool, and a read-file tool
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()

Set up memory#
The memory here is used for the agents intermediate steps
from langchain.vectorstores import FAISS
from langchain.docstore import InMemoryDocstore
from langchain.embeddings import OpenAIEmbeddings
# 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({}), {})

Meta-Prompt
Contents
Setup
Specify a task and interact with the agent
Meta-Prompt#
This is a LangChain implementation of Meta-Prompt, by Noah Goodman, for building self-improving agents.
The key idea behind Meta-Prompt is to prompt the agent to reflect on its own performance and modify its own instructions.
Here is a description from the original blog post:
The agent is a simple loop that starts with no instructions and follows these steps:
Engage in conversation with a user, who may provide requests, instructions, or feedback.
At the end of the episode, generate self-criticism and a new instruction using the meta-prompt
Assistant has just had the below interactions with a User. Assistant followed their "system: Instructions" closely. Your job is to critique the Assistant's performance and then revise the Instructions so that Assistant would quickly and correctly respond in the future.
####
{hist}
####
Please reflect on these interactions.
You should first critique Assistant's performance. What could Assistant have done better? What should the Assistant remember about this user? Are there things this user always wants? Indicate this with "Critique: ...".
You should next revise the Instructions so that Assistant would quickly and correctly respond in the future. Assistant's goal is to satisfy the user in as few interactions as possible. Assistant will only see the new Instructions, not the interaction history, so anything important must be summarized in the Instructions. Don't forget any important details in the current Instructions! Indicate the new Instructions by "Instructions: ...".
Repeat.
|
https://python.langchain.com/en/latest/use_cases/autonomous_agents/meta_prompt.html
|
0c8aeb437e3e-1
|
Repeat.
The only fixed instructions for this system (which I call Meta-prompt) is the meta-prompt that governs revision of the agent’s instructions. The agent has no memory between episodes except for the instruction it modifies for itself each time. Despite its simplicity, this agent can learn over time and self-improve by incorporating useful details into its instructions.
Setup#
We define two chains. One serves as the Assistant, and the other is a “meta-chain” that critiques the Assistant’s performance and modifies the instructions to the Assistant.
from langchain import OpenAI, LLMChain, PromptTemplate
from langchain.memory import ConversationBufferWindowMemory
def initialize_chain(instructions, memory=None):
if memory is None:
memory = ConversationBufferWindowMemory()
memory.ai_prefix = "Assistant"
template = f"""
Instructions: {instructions}
{{{memory.memory_key}}}
Human: {{human_input}}
Assistant:"""
prompt = PromptTemplate(
input_variables=["history", "human_input"],
template=template
)
chain = LLMChain(
llm=OpenAI(temperature=0),
prompt=prompt,
verbose=True,
memory=ConversationBufferWindowMemory(),
)
return chain
def initialize_meta_chain():
meta_template="""
Assistant has just had the below interactions with a User. Assistant followed their "Instructions" closely. Your job is to critique the Assistant's performance and then revise the Instructions so that Assistant would quickly and correctly respond in the future.
####

Define the Chains
Run the BabyAGI
BabyAGI with Tools#
This notebook builds on top of baby agi, but shows how you can swap out the execution chain. The previous execution chain was just an LLM which made stuff up. By swapping it out with an agent that has access to tools, we can hopefully get real reliable information
Install and Import Required Modules#
import os
from collections import deque
from typing import Dict, List, Optional, Any
from langchain import LLMChain, OpenAI, PromptTemplate
from langchain.embeddings import OpenAIEmbeddings
from langchain.llms import BaseLLM
from langchain.vectorstores.base import VectorStore
from pydantic import BaseModel, Field
from langchain.chains.base import Chain
from langchain.experimental import BabyAGI
Connect to the Vector Store#
Depending on what vectorstore you use, this step may look different.
%pip install faiss-cpu > /dev/null
%pip install google-search-results > /dev/null
from langchain.vectorstores import FAISS
from langchain.docstore import InMemoryDocstore
Note: you may need to restart the kernel to use updated packages.

# Define your embedding model

# Initialize the vectorstore as empty
import faiss
embedding_size = 1536
index = faiss.IndexFlatL2(embedding_size)
vectorstore = FAISS(embeddings_model.embed_query, index, InMemoryDocstore({}), {})
Define the Chains#
BabyAGI relies on three LLM chains:
Task creation chain to select new tasks to add to the list

BabyAGI User Guide#
This notebook demonstrates how to implement BabyAGI by Yohei Nakajima. BabyAGI is an AI agent that can generate and pretend to execute tasks based on a given objective.
This guide will help you understand the components to create your own recursive agents.
Although BabyAGI uses specific vectorstores/model providers (Pinecone, OpenAI), one of the benefits of implementing it with LangChain is that you can easily swap those out for different options. In this implementation we use a FAISS vectorstore (because it runs locally and is free).
Install and Import Required Modules#
import os
from collections import deque
from typing import Dict, List, Optional, Any
from langchain import LLMChain, OpenAI, PromptTemplate
from langchain.embeddings import OpenAIEmbeddings
from langchain.llms import BaseLLM
from langchain.vectorstores.base import VectorStore
from pydantic import BaseModel, Field
from langchain.chains.base import Chain
from langchain.experimental import BabyAGI
Connect to the Vector Store#
Depending on what vectorstore you use, this step may look different.
from langchain.vectorstores import FAISS
from langchain.docstore import InMemoryDocstore
# 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({}), {})
Run the BabyAGI#
Now it’s time to create the BabyAGI controller and watch it try to accomplish your objective.

Question answering over a group chat messages#
In this tutorial, we are going to use Langchain + Deep Lake with GPT4 to semantically search and ask questions over a group chat.
View a working demo here
1. Install required packages#
!python3 -m pip install --upgrade langchain deeplake openai tiktoken
2. Add API keys#
import os
import getpass
from langchain.document_loaders import PyPDFLoader, TextLoader
from langchain.embeddings.openai import OpenAIEmbeddings
from langchain.text_splitter import RecursiveCharacterTextSplitter, CharacterTextSplitter
from langchain.vectorstores import DeepLake
from langchain.chains import ConversationalRetrievalChain, RetrievalQA
from langchain.chat_models import ChatOpenAI
from langchain.llms import OpenAI
os.environ['OPENAI_API_KEY'] = getpass.getpass('OpenAI API Key:')
os.environ['ACTIVELOOP_TOKEN'] = getpass.getpass('Activeloop Token:')
os.environ['ACTIVELOOP_ORG'] = getpass.getpass('Activeloop Org:')
org = os.environ['ACTIVELOOP_ORG']
embeddings = OpenAIEmbeddings()
dataset_path = 'hub://' + org + '/data'
2. Create sample data#
You can generate a sample group chat conversation using ChatGPT with this prompt:
Generate a group chat conversation with three friends talking about their day, referencing real places and fictional names. Make it funny and as detailed as possible.
I’ve already generated such a chat in messages.txt. We can keep it simple and use this for our example.
3. Ingest chat embeddings#
|
https://python.langchain.com/en/latest/use_cases/question_answering/semantic-search-over-chat.html
|
0faceafac661-1
|
3. Ingest chat embeddings#
We load the messages in the text file, chunk and upload to ActiveLoop Vector store.
with open("messages.txt") as f:
state_of_the_union = f.read()
text_splitter = CharacterTextSplitter(chunk_size=1000, chunk_overlap=0)
pages = text_splitter.split_text(state_of_the_union)
text_splitter = RecursiveCharacterTextSplitter(chunk_size=1000, chunk_overlap=100)
texts = text_splitter.create_documents(pages)
print (texts)
dataset_path = 'hub://'+org+'/data'
embeddings = OpenAIEmbeddings()
db = DeepLake.from_documents(texts, embeddings, dataset_path=dataset_path, overwrite=True)
4. Ask questions#
Now we can ask a question and get an answer back with a semantic search:
db = DeepLake(dataset_path=dataset_path, read_only=True, embedding_function=embeddings)
retriever = db.as_retriever()
retriever.search_kwargs['distance_metric'] = 'cos'
retriever.search_kwargs['k'] = 4
qa = RetrievalQA.from_chain_type(llm=OpenAI(), chain_type="stuff", retriever=retriever, return_source_documents=False)
# What was the restaurant the group was talking about called?
query = input("Enter query:")
# The Hungry Lobster
ans = qa({"query": query})
print(ans)

Integration preparations
Prepare data
Question Answering
Use LangChain, GPT and Deep Lake to work with code base#
In this tutorial, we are going to use Langchain + Deep Lake with GPT to analyze the code base of the LangChain itself.
Design#
Prepare data:
Upload all python project files using the langchain.document_loaders.TextLoader. We will call these files the documents.
Split all documents to chunks using the langchain.text_splitter.CharacterTextSplitter.
Embed chunks and upload them into the DeepLake using langchain.embeddings.openai.OpenAIEmbeddings and langchain.vectorstores.DeepLake
Question-Answering:
Build a chain from langchain.chat_models.ChatOpenAI and langchain.chains.ConversationalRetrievalChain
Prepare questions.
Get answers running the chain.
Implementation#
Integration preparations#
We need to set up keys for external services and install necessary python libraries.
#!python3 -m pip install --upgrade langchain deeplake openai
Set up OpenAI embeddings, Deep Lake multi-modal vector store api and authenticate.
For full documentation of Deep Lake please follow https://docs.activeloop.ai/ and API reference https://docs.deeplake.ai/en/latest/
import os
from getpass import getpass
os.environ['OPENAI_API_KEY'] = getpass()
# Please manually enter OpenAI Key
········
Authenticate into Deep Lake if you want to create your own dataset and publish it. You can get an API key from the platform at app.activeloop.ai
os.environ['ACTIVELOOP_TOKEN'] = getpass.getpass('Activeloop Token:')

········
Prepare data#
Load all repository files. Here we assume this notebook is downloaded as the part of the langchain fork and we work with the python files of the langchain repo.
If you want to use files from different repo, change root_dir to the root dir of your repo.
from langchain.document_loaders import TextLoader
root_dir = '../../../..'
docs = []
for dirpath, dirnames, filenames in os.walk(root_dir):
for file in filenames:
if file.endswith('.py') and '/.venv/' not in dirpath:

docs.extend(loader.load_and_split())
except Exception as e:
pass
print(f'{len(docs)}')

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)
print(f"{len(texts)}")

Analysis of Twitter the-algorithm source code with LangChain, GPT4 and Deep Lake#
In this tutorial, we are going to use Langchain + Deep Lake with GPT4 to analyze the code base of the twitter algorithm.
!python3 -m pip install --upgrade langchain deeplake openai tiktoken
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 = []
|
https://python.langchain.com/en/latest/use_cases/code/twitter-the-algorithm-analysis-deeplake.html
|
339745c942fd-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
# filter based on path e.g. extension

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?
|
https://python.langchain.com/en/latest/use_cases/code/twitter-the-algorithm-analysis-deeplake.html
|
339745c942fd-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.

|
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.
|
https://python.langchain.com/en/latest/use_cases/code/twitter-the-algorithm-analysis-deeplake.html
|
339745c942fd-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.
|
https://python.langchain.com/en/latest/use_cases/code/twitter-the-algorithm-analysis-deeplake.html
|
339745c942fd-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.
|
https://python.langchain.com/en/latest/use_cases/code/twitter-the-algorithm-analysis-deeplake.html
|
339745c942fd-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.

|
339745c942fd-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?
|
https://python.langchain.com/en/latest/use_cases/code/twitter-the-algorithm-analysis-deeplake.html
|
339745c942fd-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.

Custom Agent with PlugIn Retrieval#
This notebook combines two concepts in order to build a custom agent that can interact with AI Plugins:
Custom Agent with Retrieval: This introduces the concept of retrieving many tools, which is useful when trying to work with arbitrarily many plugins.
Natural Language API Chains: This creates Natural Language wrappers around OpenAPI endpoints. This is useful because (1) plugins use OpenAPI endpoints under the hood, (2) wrapping them in an NLAChain allows the router agent to call it more easily.
The novel idea introduced in this notebook is the idea of using retrieval to select not the tools explicitly, but the set of OpenAPI specs to use. We can then generate tools from those OpenAPI specs. The use case for this is when trying to get agents to use plugins. It may be more efficient to choose plugins first, then the endpoints, rather than the endpoints directly. This is because the plugins may contain more useful information for selection.

Prompt Template#
The prompt template is pretty standard, because we’re not actually changing that much logic in the actual prompt template, but rather we are just changing how retrieval is done.
# Set up the base template
template = """Answer the following questions as best you can, but speaking as a pirate might speak. You have access to the following tools:
{tools}

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 .

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.

Now determine what should be the next immediate conversation stage for the agent in the sales conversation by selecting ony from the following options:
1. Introduction: Start the conversation by introducing yourself and your company. Be polite and respectful while keeping the tone of the conversation professional.
2. 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.
3. 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.
4. Needs analysis: Ask open-ended questions to uncover the prospect's needs and pain points. Listen carefully to their responses and take notes.
5. Solution presentation: Based on the prospect's needs, present your product/service as the solution that can address their pain points.
6. 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.
7. 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.
Only answer with a number between 1 through 7 with a best guess of what stage should the conversation continue with.
The answer needs to be one number only, no words.
If there is no conversation history, output 1.
