Core
Model Registry and PromotionA model registry is the source of truth for every model version, what data and code produced it, and how it scored on your eval suite. Promotion is the gated path from a registered candidate to live serving: pass the gates, soak in shadow or canary, then swap an alias so traffic moves atomically and rollback is one step.🔁 MLOps & LifecycleSign in

REST API Design for IntegrationsThe API you hand a customer is the part of the deployment their engineers live with after you leave, so it is judged on how little it surprises them. Resources and verbs are the easy half; versioning, pagination, error shape and idempotency are what decide whether their integration keeps working next quarter.⚙️ System Design for AI in Production🔒 Premium

Model Versioning and MigrationThe model under your application changes whether or not you asked. Providers ship new snapshots, deprecate old ones and give you a window, so a deployment that pinned nothing has quality moving beneath it and a deployment that pinned everything eventually gets a forced cutover on someone else's schedule.🔁 MLOps & Lifecycle🔒 Premium

Mixing them in one index cannot raise an error, which is why a half-finished migration returns confident nonsense at full speed.🤖 Retrieval & Agents🔒 Premium
