Frequently asked questions

How long to build a working agent?

A demo in an afternoon. A production-worthy agent takes ~2 weeks with our lesson plan — most of that time is evals and guardrails, not the loop itself.

Do I need GPT-5 or can I use open models?

Both work. We cover model-agnostic patterns and provide reference code for hosted and local models.
