Add real personalization on Model Database: tailored onboarding, recommendation explanations, and localized copy from structured user signals.
Store mdb_live_ keys in the environment, keep them off the frontend, rotate on a schedule, and revoke instantly if one ever leaks.
What reasoning-strong models are, when step-by-step deliberation pays off versus when it is overkill, and how to route tasks accordingly.
