Open vs. closed models — who pays the frontier premium

An open model is not automatically freedom, and a closed model is not automatically lock-in. The practical question is when control, cost and local deployment matter more than paying for frontier capability.

Model reliability — when a pretty answer is not enough

Reliability is about when the model knows, when it does not, when it invents, and how often its output can be trusted in production. Elegant wording is not evidence.
