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.
Executives · AI economics
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
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.

Capabilities
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.
Route simple intents to small / cheap models, complex intents to frontier models. The gateway picks per call, not per service.
Hard caps and soft alarms per project, team, or consumer. When a budget is reached, the gateway throttles or fails over — no surprise.
Every token tagged with consumer, project, and prompt fingerprint. Cost shows up in the dashboard the day it was spent.
Prompt tokens, completion tokens, cache hits, fallbacks — broken out by model, endpoint, and consumer. Finance gets the same view as engineering.
Power users get more; weekend batch jobs get less. Quotas are a policy you write once and the gateway enforces on every call.
Use cases
Semantic cache absorbs 71% of duplicate prompts. Routing sends short intents to a smaller model; only escalations reach the frontier provider.
−58% monthly
Per-team budgets at €X. Alarms fire at 80%; throttle at 100%. The CFO sees burn rates instead of surprise invoices.
Every token is tagged with the squad that asked for it. Cost showbacks appear in the existing FinOps dashboard.
EU-hosted model handles 92% of summaries; frontier provider used only for adversarial or multi-language cases. Latency improves and spend drops together.
−42% spend, +18% latency
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.
Department quotas published. Departments see real-time burn; over-runs require a written request, not a surprise email.
Routing prefers the national Arabic model first; falls over to international providers only on miss. Sovereignty and cost align.
Semantic cache deduplicates near-identical SKU prompts. Routing handles long-form on a frontier model; short-form on a 7B open model.
−64% spend
