How to Build AI Apps That Switch Models Automatically
freeCodeCamp News
EDITOR BRIEF
The article explains why using one LLM for every request can be risky: outages can stop your app, and expensive models can waste money on simple questions. It describes a Python-based multi-model orchestrator that analyzes prompt complexity, routes requests to different models, and falls back automatically when needed.
INSIGHTS
This matters because real AI apps need reliability and cost control, not just accuracy. A good next step is to practice building a small Python router that sends easy prompts to a cheaper model and keeps a backup model ready.
