1. What is the main takeaway from "AI model families: open-weight vs closed — what actually changes — Quick Check"?

   1. Open weights give you portability, customization, and self-hosting. Closed APIs give you frontier quality and managed ops. Pick by what you'll actually use.
   2. Predict the open vs closed gap
   3. GPT-5 has a Thinking mode that takes longer but solves harder problems.
