LLM for Galaxy Clusters

In this repository we train a LLM to be an expert on galaxy clusters using a curated set of scientific articles on galaxy clusters.

This app can be found running at https://llm-galaxyclusters.streamlit.app/.

How to use:

• Create a .env file containing OPENAI_API_KEY.
• Run streamlit run LLM-GalaxyClusters.py

How does it work?

This code has two main components:

1. The code ingests a curated set of scientific articles on galaxy clusters in the form of PDFs. Then, it creates vector embeddings for these articles and saves them in a chromadb.sqlite3 database.
2. The code uses LangChain to call a LLM (chatgpt-3.5-turbo) to generate answers based off the users questions. The responses are augmented using the RAG technique that concentrates the LLM's answer based off the ingested PDFs.

The list of scientific articles used to train the LLM can be found in LLM-GalaxyClusters.bib.
