Artificial intelligence for Software Testing | Artificial Intelligence in Test Automation - LLMs in Python Explained: How to Build, Run & Deploy LLM Apps — LoRA, FastAPI, Exception Handling

This practical 7-minute guide shows how to get started with LLMs in Python and move from prototype to production. Learn why Python is the go-to language for LLMs, how to run your first program, when to use API vs local models, how to make models smarter with prompting and LoRA fine-tuning, and how to deploy an LLM app using FastAPI or Streamlit. What you’ll learn: • Why Python for LLMs and developer tooling • Your first LLM program: from zero to generation • API vs local model trade-offs (cost, latency, privacy) • LoRA fine-tuning and few-shot prompt engineering for better results • Deploying LLM apps with FastAPI and Streamlit; basic error handling and backoff Recommended next steps: • Try a local model to reduce latency and protect private data. • Experiment with LoRA adapters for low-cost customization. • Prototype deployment with FastAPI for a production-ready endpoint or Streamlit for demos.
