Show HN: Neum AI – Open-source large-scale RAG framework

#1
Over the last couple months we have been supporting developers in building large-scale RAG pipelines to process millions of pieces of data.

We documented our approach in an HN post (https://news.ycombinator.com/item?id=37824547) a couple weeks ago. Today, we are open sourcing the framework we have developed.

The framework focuses on RAG data pipelines and provides scale, reliability, and data synchronization capabilities out of the box.

For those newer to RAG, it is a technique to provide context to Large Language Models. It consists of grabbing pieces of information (i.e. pieces of news articles, papers, descriptions, etc.) and incorporating them into prompts to help contextualize the responses. The technique goes one level deeper in finding the right pieces of information to incorporate. The search for relevant information is done through the use of vector embeddings and vector databases.

Those pieces of news articles, papers, etc. are transformed into a vector embedding that represents the semantic meaning of the information. These vector representations are organized into indexes where we can quickly search for the pieces of information that most closely resembles (from a semantic perspective) a given question or query. For example, if I take news articles from this year, vectorize them, and add them to an index, I can quickly search for pieces of information about the US elections.

To help achieve this, the Neum AI framework features:

Starting with built-in data connectors for common data sources, embedding services and vector stores, the framework provides modularity to build data pipelines to your specification.

The connectors support pre-processing capabilities to define loading, chunking and selecting strategies to optimize content to be embedded. This also includes extracting metadata that is going to be associated to a given vector.

The generated pipelines support large scale jobs through a high throughput distributed architecture. The connectors allow you to parallelize tasks like downloading documents, processing them, generating embedding and ingesting data into the vector DB.

For data sources that might be continuously changing, the framework supports data scheduling and synchronization. This includes delta syncs where only new data is pulled.

Once data is transformed into a vector database, the framework supports querying of the data including hybrid search using the available metadata added during pre-processing. As part of the querying process, the framework provides capabilities to capture feedback on retrieved data as well as run evaluations against different pipeline configurations.

Cool. Do you do any of the relevance calculations directly, or is that all handled by Weaviate? If so, is there any way to influence that part of it, or is it something of a black box?

Relevance calculations are handled by the vector db but we try to improve such relevance with the use of metadata (you will see how our components have "selectors" so that metadata can flow all the way to the vector database at the vector level and have an influence when results/scores get retrieved at search time)

If someone is about to start their project using Haystack would you suggest they instead look at Neumtry?

Well, of course I'm biased on the answer :). But to give a not-so-biased answer, I would first try to understand what the project is about and whether RAG is a priority in it. If the project is leveraging agents and LLMs without worrying too much on context/up-to-date data then Haystack could be a good option. If the focus is to eventually use RAG then our framework could help.

Additionally, there might be a potential route where both are used, depending on the use case.

Feel free to dm if you want to chat further on this!

How does the improve upon retrieval compared to just using any vector db and semantic search?

Co-founder here :)

Today, it is mostly about convenience. We provide abstractions in the form of a pipeline that encompasses a data source, embed and sink definition. This means that you don't have to think about embedding your query or what class you used to add the data into the vector DB.

In the future, we have some additional abstractions that we are adding that will add more convenience. For example, we are working on a concept of pipeline collections so that you can search across multiple indexes but get unified results. We are also adding more automation around metadata given that as part of the pipeline configuration we know what metadata was added and examples of it, so we can help translate queries into hybrid search. I think about it as a self-query retriever from Langchain or Llama Index but that automatically has context of the data at hand. (no need to provide attributes)

Are there any specific retrieval capabilities you are looking for?
