Question 1

What are LLM service tiers and why do they cost different amounts?

Accepted Answer

The same model can be billed at different processing tiers that trade latency against price. Standard is the synchronous list price. Batch and flex tiers run the same request asynchronously or at lower priority for roughly half the standard rate — they are meant for work that can wait minutes or hours, like bulk classification, embeddings, offline summarisation or nightly report generation. Priority processing goes the other way: you pay a premium above standard to get faster, more consistent latency and better reliability during load spikes, which matters for interactive, user-facing calls. The tokens are identical; you are paying for how quickly and how reliably they are served. This calculator lets you split your traffic across those tiers and see the blended bill.

Question 2

How much can batch or flex processing actually save?

Accepted Answer

The discount is typically around 50% off the standard rate, so every slice of traffic you can move to a batch or flex tier costs about half. The catch is latency: batch jobs can take up to a day to return and flex requests can be slower or occasionally queued, so only genuinely deferrable work qualifies. The lever is the share of your volume that can tolerate the wait — a pipeline that is 80% offline batch and 20% interactive lands near a 40% overall saving, while an all-interactive product saves nothing this way. The sweep table on this page shows the blended cost at every deferrable share so you can see how much a given amount of batching is worth before you re-architect anything.

Question 3

Is priority processing worth the premium?

Accepted Answer

Only for the traffic where latency has real value — a checkout flow, a live agent, anything a user is waiting on — and only for that slice, not your whole volume. Priority typically costs meaningfully more than standard per token, so putting all traffic on it is the most expensive way to run. The honest test is whether the faster, more reliable response is worth the extra dollars it adds, which this calculator prints as a standalone number: the priority premium in dollars per month for the critical share you selected. If that figure is small relative to the revenue those interactive calls protect, it is cheap insurance; if it is large and the latency gain is cosmetic, it is waste.

Question 4

How do I split traffic across tiers in practice?

Accepted Answer

Start by tagging each call path by how much delay it can tolerate. Anything a user is not actively waiting for — overnight jobs, backfills, evaluations, bulk enrichment — goes to batch or flex at the discounted rate. Anything a user is waiting on but that is not latency-critical stays on standard. Reserve priority for the narrow set of interactive paths where a slow or dropped response costs you money. Then set those three shares here to see the blended rate and the saving versus running everything on standard. Most teams find the biggest win is not priority at all but simply moving the offline half of their volume onto batch, which this calculator makes obvious.
