This notebook shows how to retrieve documents from Rememberizer the Document format that is used downstream.
Preparation
You will need an API key: you can get one after creating a common knowledge at https://rememberizer.ai. Once you have an API key, you must set it as an environment variable REMEMBERIZER_API_KEY or pass it as rememberizer_api_key when initializing RememberizerRetriever.
RememberizerRetriever has these arguments:
- optional top_k_results: default=10. Use it to limit number of returned documents.
- optional rememberizer_api_key: required if you don’t set the environment variable REMEMBERIZER_API_KEY.
get_relevant_documents() has one argument, query: free text which used to find documents in the common knowledge of Rememberizer.ai

retriever = RememberizerRetriever(top_k_results=5)
docs = retriever.get_relevant_documents(query="How does Large Language Models works?")

before, or contextualized in new ways. on some level they " understand " semantics in that they can associate words and concepts by their meaning, having seen them grouped together in that way millions or billions of times. how developers can quickly start building their own llms to build llm applications, developers need easy access to multiple data sets, and they need places for those data sets

-> **Question**: What is RAG?
**Answer**: RAG stands for Retrieval-Augmented Generation. It is an AI framework that retrieves facts from an external knowledge base to enhance the responses generated by Large Language Models (LLMs) by providing up-to-date and accurate information. This framework helps users understand the generative process of LLMs and ensures that the model has access to reliable information sources.
-> **Question**: How does Large Language Models works?
**Answer**: Large Language Models (LLMs) work by analyzing massive data sets of language to comprehend and generate human language text. They are built on machine learning, specifically deep learning, which involves training a program to recognize features of data without human intervention. LLMs use neural networks, specifically transformer models, to understand context in human language, making them better at interpreting language even in vague or new contexts. Developers can quickly start building their own LLMs by accessing multiple data sets and using services like Cloudflare's Vectorize and Cloudflare Workers AI platform.
