What is this?
Enterprise rec systems add governance, A/B tests, multi-tenant isolation, and offline/online parity.
Why should you care?
AIPredict serves multiple merchants — each needs separate models, metrics, and rollout controls.
See it live — copy this example
Use a .NET console or Web API project with Microsoft.ML. Run dotnet run after pasting.
// tenant-aware model registry
var modelPath = Environment.GetEnvironmentVariable($"REC_MODEL_{tenantId}") ?? "models/default-rec.zip";
var loaded = ml.Model.Load(modelPath, out var schema);
services.AddPredictionEnginePool<UserProduct, ProductScore>()
.FromFile(modelPath, schemaDefinition: schema);What happened?
- Per-tenant model paths, champion/challenger flags, and audit logs keep enterprise recs maintainable.
- Follow the steps below — typing the code yourself is the fastest way to learn.
Practice next
- Env var per tenant model.
- Register pool from file.
- Log model version on each response.
- Shadow challenger model.
- Per-tenant fallback to popular.
Remember
Tenant isolation. Versioned zips. Audit + A/B hooks.
AIPredict multi-tenant recs
Merchant A and B use separate zips.
Outcome: No cross-tenant leakage in rankings.
