LLM - Crack and Chunk Data

llm_rag_crack_and_chunk

Overview

Creates chunks no larger than chunk_size from input_data, extracted document titles are prepended to each chunk

LLM models have token limits for the prompts passed to them, this is a limiting factor at embedding time and even more limiting at prompt completion time as only so much context can be passed along with instructions to the LLM and user queries. Chunking allows splitting source data of various formats into small but coherent snippets of information which can be 'packed' into LLM prompts when asking for answers to user query related to the source documents.

Supported formats: md, txt, html/htm, pdf, ppt(x), doc(x), xls(x), py

Version: 0.0.70
