Sixty-five models offer a paid express lane: lower latency, reserved capacity and protection from queueing at peak load, typically at twice the standard rate. OpenAI calls it Fast mode, Anthropic offers it on Opus 5 and Opus 4.8, Google sells Priority, xAI doubles the rate for the same effect.

Output here runs from $1.20 to $50 per million tokens before the multiplier. The tier earns its price in two situations: a user is waiting and the difference between two seconds and eight is a lost conversion, or you have a contractual latency commitment. For batch work it is money burned.

Double rate, same answerYou buy latency and capacity, not quality.
Peak protectionThe value shows up under load, when standard queues lengthen.
Opposite of batchOne trades money for speed, the other speed for money.

Models with this capability

How to choose

  • Measure your actual p95 latency on standard tier before paying for priority.
  • Apply it per endpoint, not account-wide — only user-facing paths need it.
  • Check whether the vendor guarantees capacity or merely prioritises it.
  • Reprice regularly; standard-tier latency improves as vendors add capacity.

Common mistakes

Priority on background jobsPaying double for work nobody is waiting on.
Using it to mask a slow modelA smaller model on standard tier is often faster and cheaper than a big one on priority.

Who this suits

Conversational productsWhere a pause reads as a broken interface.
Regulated servicesContractual response-time commitments.
Peak-heavy businessesTraffic concentrated into narrow windows.

Frequently asked questions

What does priority actually buy?

Lower latency and protection from queueing at peak load. It does not change answer quality.

When is it worth double?

A user is waiting and seconds cost conversions, or you have a contractual latency commitment. Otherwise it is money burned.

What is the opposite trade?

Batch processing — half price in exchange for hours of delay.

Does priority improve accuracy?

No. Identical model, identical output distribution.

Can I switch per request?

Yes with most vendors — it is a parameter, not an account setting.
