Advanced Memory in LangChain
From Entities to Knowledge Graphs
In the previous installment, we delved deep into the essence of LangChain’s Memory module, unearthing its potential to foster conversation continuity. As language models evolve, so too does the demand for more sophisticated memory techniques. Thus, as we continue our journey, we set our sights on advanced memory types within LangChain, from Entity Memory to Knowledge Graphs.
Entity Memory
At the heart of many sophisticated interactions lies the ability to remember specific entities. LangChain’s Entity Memory allows models to retain and build upon the context of entities within a conversation. Whether it’s remembering the details about “Abi” and her contribution to the LLMOps community or the nuances of a specific conversation template, this memory type ensures that the model can provide responses that are not only accurate but deeply contextual.
Knowledge Graph Memory
Moving a notch higher, LangChain introduces ConversationKGMemory. This memory type harnesses the power of knowledge graphs to store and recall information. By doing so, it aids the model in comprehending the relationships between different entities, enhancing its ability to respond based on the intricate web of connections and historical context.
Summary Memories
As conversations grow and evolve, it becomes crucial to distill the essence of interactions. With ConversationSummaryMemory and ConversationSummaryBufferMemory, LangChain offers a solution to maintain a concise history. These memory types condense conversations into manageable summaries, ensuring that the model remains aware of the broader context without getting bogged down by excessive details.
Token Buffer
Lastly, the ConversationTokenBufferMemory serves as a testament to LangChain’s commitment to flexibility. By using token length to determine memory flush, this memory type adapts to varied conversation depths and lengths, ensuring optimal performance and relevance in responses.
In essence, as we navigate the maze of conversations, LangChain’s advanced memory capabilities stand as beacons, guiding us to richer, more context-aware interactions. Whether you’re building a chatbot for customer support, a virtual assistant for personalized tasks, or a sophisticated AI agent for simulations, understanding and leveraging these advanced memory types can be the key to unlocking unparalleled conversational depth and continuity.
Here’s to making every conversation count, and to a future where AI remembers not just words, but the very essence of interactions.

Entity
Entity Memory in LangChain is a feature that allows the model to remember facts about specific entities in a conversation.
It uses an LLM to extract information on entities and builds up its knowledge about those entities over time. Entity Memory is useful for maintaining context and retaining information about entities mentioned in the conversation. It can help the model provide accurate and relevant responses based on the history of the conversation.
You should use Entity Memory when you want the model to know specific entities and their associated information.
It can be particularly helpful in scenarios where you want the model to remember and refer back to previous mentions of entities in the conversation.
Entity Memory enhances a model’s ability to understand and respond to conversations by keeping track of important information about entities.

Knowledge Graph Memory
ConversationKGMemory, also known as Conversation Knowledge Graph Memory, is a feature in LangChain that allows the model to store and retrieve information as a knowledge graph.
It uses an LLM to extract knowledge from the conversation and build a memory of the entities and their associated information, helping maintain context and retain knowledge about entities mentioned in the conversation.
Storing information in a knowledge graph format enables the model to understand the relationships between entities and their attributes, helping the model provide accurate and relevant responses based on the history of the conversation.
You should use ConversationKGMemory when you want the model to have a structured representation of the conversation’s knowledge.
It’s super valuable for scenarios where you want the model to remember and refer back to previous mentions of entities in the conversation, allowing for more advanced reasoning and understanding of the context.
The following is a back-and-forth conversation. What I want you to pay attention to is the “Relevant Information” that the LLM is retaining about the conversation:

ConversationSummaryMemory
To condense information from a conversation over time, a ConversationSummaryMemory can come in handy.
This memory type is designed to keep track of all interactions during a conversation, and it can be useful only to use the most recent ones.
You would need ConversationSummaryMemory when you want to have a concise representation of the conversation’s history without using too many tokens.
It allows the model to understand the overall context and key points of the conversation without being overwhelmed by excessive details.
You can tell if you need ConversationSummaryMemory if you find that the conversation history is becoming too long and complex for the model to handle effectively.
By using ConversationSummaryMemory, you can condense the conversation into a more manageable summary, making it easier for the model to process and respond accurately.
from langchain.memory import ConversationSummaryMemory, ChatMessageHistory
from langchain.llms import OpenAI
from langchain.chains import ConversationChain
llm = OpenAI(temperature=0)
conversation_with_summary = ConversationChain(
llm=llm,
memory=ConversationSummaryMemory(llm=OpenAI()),
verbose=True
)
conversation_with_summary.predict(input="Hi, what's up?")
I won’t bore you with the back and forth, but the end result after the conversation will look something like this:

Prompt after formatting:
The following is a friendly conversation between a human and an AI. The AI is talkative and provides lots of specific details from its context. If the AI does not know the answer to a question, it truthfully says it does not know.
Current conversation:
The human asks how the AI is doing, and the AI replies that it is helping a customer with a technical issue. The customer is having trouble with their printer and the AI is helping them troubleshoot the issue and figure out what the problem is.
Human: Very cool -- what is the scope of the project?
AI:
> Finished chain.
The scope of the project is to help the customer troubleshoot their printer issue. I'm currently helping them identify the source of the problem and then providing them with a solution.
Conversation Summary Buffer
ConversationSummaryBufferMemoryin LangChain is a type of memory that keeps track of the interactions in a conversation over time.
It uses a sliding window approach, where only the last K interactions are stored.
This helps prevent the buffer from becoming too large and overwhelming the model.
Conversation Buffer Memory is useful for maintaining a concise conversation history without using excessive tokens.
It allows the model to understand the context and key points of the conversation without being burdened by excessive details.
You would need Conversation Buffer Memory when the conversation history becomes too long and complex for the model to handle effectively.
Using Conversation Buffer Memory, you can condense the conversation into a more manageable summary, making it easier for the model to process and respond accurately.
from langchain.memory import ConversationSummaryBufferMemory
from langchain.llms import OpenAI
llm = OpenAI()
memory_summary = ConversationSummaryBufferMemory(llm=llm, max_token_limit=100)
conversation_with_summary = ConversationChain(
llm=llm,
memory=ConversationSummaryBufferMemory(llm=llm, max_token_limit=40),
verbose=True
)
conversation_with_summary.predict(input="Yo! Wassup, let's gooo LFG!")
And to get the full summary of the conversation:
conversation_with_summary.memory.moving_summary_buffer
Which will yield something like:
The human greets the AI and asks to "LFG" and the AI responds with enthusiasm. The human explains they are trying to teach people about memory with LangChain, a platform for developers to build applications with LLMs (Long-Lived Memory) through composability. The AI expresses interest and clarifies that this means applications can be built from existing components, and the Long-Lived Memory is used to keep track of any changes or additions to the existing components, to which the human confirms is the gist of it.
Conversation Token Buffer
As an FYI there is another flavor of buffer memory.
ConversationTokenBufferMemory keeps a buffer of recent interactions in memory, and uses token length rather than number of interactions to determine when to flush interactions.
The usage pattern is the same as above.
Conclusion
As we’ve journeyed through the intricate facets of LangChain’s advanced memory systems, it’s evident that the future of conversational AI hinges on the ability to retain, recall, and reason with context. From entities to knowledge graphs, LangChain’s memory tools are not mere features; they represent a paradigm shift in how we view and engage with AI.
In the realm of chatbots and virtual assistants, gone are the days of isolated interactions. With LangChain, every conversation can continue, every response can be rooted in history, and every entity can be remembered with clarity. These advanced memory systems not only enhance the depth of interactions but also bridge the temporal gaps, ensuring continuity.
As we look forward to what’s next in the LangChain saga, one thing is clear: with such robust memory capabilities, the possibilities are as vast as the conversations they will empower.
The age of truly context-aware AI is upon us, and LangChain is leading the charge.
