Invoice Data Processing with Mistral LLM on Local CPU

I explain the solution to extract invoice document fields with open-source LLM Mistral. It runs on CPU and doesn't require Cloud machine. I'm using Mistral 7B LLM model, Langchain, Ctransformers and Faiss vector store to run it on a local CPU machine. This approach gives a great advantage for enterprise systems, when running ML models on Cloud is not allowed for privacy reasons.
