AI cost control — Use case

Token-aware routing, semantic caching, per-team budgets, and per-call attribution. Watch AI spend turn from a quarterly surprise into a line you control.

Apinizer's AI Gateway routes calls to the cheapest model that satisfies the SLA, caches answers semantically, enforces per-team budgets, and attributes every token to the consumer that asked for it.

The problem

The problem

AI bills don't show up in the procurement cycle. They show up in the close.

Engineers point a service at a frontier model. Token meters spin. The bill is fine in week one, alarming in month one, and a board-level conversation by quarter end. By then attribution is impossible — twelve teams share one API key, and nobody knows which prompt cost what. Apinizer puts every AI call through a gateway that meters, attributes, caches, and routes — before the spend happens.

At a glance

40-70% — spend cut (semantic cache + smart routing)
100% — calls attributed (per team / project / consumer)
Real-time — budget alarms

Capabilities

Semantic caching

Equivalent prompts hit cache, not the model. 'Summarize this contract' on the same contract serves from cache; the underlying model is never called twice for the same answer.

Smart model routing

Write the rules once — consumer, project, headers, model class — or let the gateway pick the cheapest or fastest model off the catalog and live health probes. The decision is per call, not per service.

Per-team budgets

Hard caps and soft alarms per project, team, or consumer. When a budget is reached, the gateway throttles or fails over — no surprise.

Per-call attribution

Every token tagged with consumer, project, and model. Cost shows up in the dashboard the day it was spent.

Token economics

Prompt tokens, completion tokens, cache hits, fallbacks — broken out by model, endpoint, and consumer. Finance gets the same view as engineering.

Quotas with policy

Power users get more; weekend batch jobs get less. Quotas are a policy you write once and the gateway enforces on every call.

Real-world examples

Banking

Scenario: Istanbul bank cuts AI spend 58% on customer-service summaries

Outcome: Semantic cache absorbs 71% of duplicate prompts. Routing sends short prompts to a smaller model; only escalations reach the frontier provider.

Metric: −58% monthly

Manufacturing

Scenario: Stuttgart OEM caps each engineering team's monthly AI budget

Outcome: Per-team budgets at €X. Alarms fire at 80%; throttle at 100%. The CFO sees burn rates instead of surprise invoices.

E-commerce

Scenario: Amsterdam marketplace attributes AI cost back to product squads

Outcome: Every token is tagged with the squad that asked for it. Cost showbacks appear in the existing FinOps dashboard.

Insurance

Scenario: Paris insurer routes claim summarization to a regional model

Outcome: EU-hosted model handles 92% of summaries; frontier provider used only for adversarial or multi-language cases. Latency improves and spend drops together.

Metric: −42% spend, +18% latency

Telecom

Scenario: Madrid carrier shifts batch enrichment to off-peak smaller models

Outcome: Time-of-day policy: night batch on the cheap tier, daytime live traffic on the premium tier. Cost-to-serve drops without an SLA change.

Public sector

Scenario: Prague ministry budgets AI per department in advance

Outcome: Department quotas published. Departments see real-time burn; over-runs require a written request, not a surprise email.

Government

Scenario: Riyadh agency uses a national-language model for 80% of calls

Outcome: Routing prefers the national Arabic model first; falls over to international providers only on miss. Sovereignty and cost align.

Retail

Scenario: Milan retailer cuts product-description AI cost 64%

Outcome: Semantic cache deduplicates near-identical SKU prompts. Routing handles long-form on a frontier model; short-form on a 7B open model.

Metric: −64% spend
