Additionally, the model could be trained on a combination of these data sources to provide a more comprehensive understanding of the context. The human then asked which data source types could be used to give context to the model, to which the AI responded that there are many different types of data sources that could be used, such as structured data sources, unstructured data sources, or external APIs. The human asked the AI to think of different possibilities, and the AI suggested three options: using the large language model to generate a set of candidate answers and then using external knowledge to filter out the most relevant answers, score and rank the answers, or refine the answers. The human expressed interest in exploring the potential of integrating Large Language Models with external knowledge, to which the AI responded positively and asked for more information. The human greeted the AI with a good morning, to which the AI responded with a good morning and asked how it could help. We initialize the ConversationChain with the summary memory like so: In the context of (/learn/langchain-intro/, they are all built on top of the ConversationChain.įollowing the initial prompt, we see two parameters parameter.
There are several ways that we can implement conversational memory. Conversational memory allows us to do that. There are many applications where remembering previous interactions is very important, such as chatbots. The only thing that exists for a stateless agent is the current input, nothing else.
By default, LLMs are stateless - meaning each incoming query is processed independently of other interactions. The memory allows a Large Language Model (LLM) to remember previous interactions with the user. Without conversational memory (right), the LLM cannot respond using knowledge of previous interactions. The blue boxes are user prompts and in grey are the LLMs responses. The LLM with and without conversational memory. It enables a coherent conversation, and without it, every query would be treated as an entirely independent input without considering past interactions. Conversational Memory for LLMs with LangchainĬonversational memory is how a chatbot can respond to multiple queries in a chat-like manner.
