# Welcome to ChatLGO

In this space we'll examine a chat application that is able to query a large repository of LGO Theses using a combination of tools provided through the LlamaIndex library.

We'll be leveraging:

- [Fine-tuned Embedding Model](https://huggingface.co./ai-maker-space/chatlgo-finetuned)
- [Cohere's Reranking Service](https://cohere.com/rerank)
- [Sub Query Query Engine](https://docs.llamaindex.ai/en/stable/examples/query_engine/sub_question_query_engine.html)

This should enable us to retrieve documents with expanded context generated by our LLM!
