What is this?
AI SaaS platforms multi-tenant ML inference with per-customer models, quotas, and billing hooks.
Why should you care?
AIPredict sells fraud scoring to merchants — each tenant needs isolation and usage metering.
See it live — copy this example
Use a .NET console or Web API project with Microsoft.ML. Run dotnet run after pasting.
app.MapPost("/api/tenants/{tenantId}/score", async (string tenantId, TxRow tx, ITenantModelStore store, PredictionEnginePool<TxRow, FraudPred> pool) =>
{
await store.EnsureLoadedAsync(tenantId, pool);
var p = pool.Predict(tx);
await usage.MeterAsync(tenantId, "fraud_score", 1);
return Results.Ok(p);
});What happened?
- Load tenant-specific zip into pool or swap engine context.
- Meter every predict for billing and quotas.
Practice next
- Tenant model store abstraction.
- Meter usage per call.
- Auth tenantId from JWT.
- Hard quota return 429.
- Tier-based model quality.
Remember
Tenant isolation. Usage metering. JWT tenant claim.
AIPredict SaaS fraud
Merchant X only loads merchant X zip.
Outcome: Usage billed per 1k scores.
