Is HELM free to use?
HELM 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.

Basic Python is enough. Functions, dictionaries and imports cover most of what HELM asks of you.
When should I not use HELM?
When something else in evals and testing fits the job better. The others in that group are listed below.
Lessons for HELM are being written. Meanwhile the APIs for AI tutorial covers the same ground: state, tools, loops, memory and human approval. Most of it carries straight over.
