Common questions
Is LiteLLM free to use?
LiteLLM is open source and free to run yourself. You still pay whichever model provider you point it at, and this tutorial is free with no signup.
Do I need to know Python to use LiteLLM?
Basic Python is enough. Functions, dictionaries and imports cover most of what LiteLLM asks of you.
When should I not use LiteLLM?
When something else in infrastructure fits the job better. The others in that group are listed below.
Lessons for LiteLLM are being written. Meanwhile the Claude Code tutorial covers the same ground: state, tools, loops, memory and human approval. Most of it carries straight over.
