Concurrent streams
1 stream
one thing talking at a time, usage on it unmetered
A stream carries one synthesis at a time, and everything said on it is unmetered. The only number you size is how many you need running at once.
The quiet cap in metered plans
Everywhere, parallel capacity means buying more streams. What differs is what sits on top: a per-character plan also bills every character, and caps how many you may buy. Here nothing is billed by the character. A stream is unlimited and unmetered.

for a short burst past your streams, included with every stream
A request that cannot be served is refused fast and retryably, one busy lane never quietly slows the others.
Sizing a fleet
- Count peak simultaneous work, not monthly minutes. Calls, narration jobs and render batches all draw on the same streams.
- Size for your ordinary busy hour, not the spike: a short burst above your streams is included at no extra charge, and a spike that lasts all day is the signal to add a stream.
- A first month exists to find the real number, against actual traffic rather than a forecast.
