The OpenAI API unlocked a whole new layer of building for me

Thanks Mate, I really appreciate that. The big shift for me was treating long runs as production workflows rather than single chat sessions. At a high level, I persist project state outside the prompt path, then bring back only the active working context needed for the next step. That lets the system continue across larger runs without constantly replaying everything that happened before. So the pattern is basically: durable project state, managed run progress, reviewable outputs, and selective context rehydration when needed. That has been one of the biggest unlocks for cost control and repeatability.
