Limits

Usage limit

Each account includes 5 hours of free usage, shared by both models.

A5S Async v1 counts the duration of each completed transcript. Failed jobs are not counted.
A5S v2 Streaming counts the audio you stream.
A file longer than your remaining usage fails with usage_limit_reached and is not counted. New requests at a used-up limit return 403 usage_limit_reached.
See what’s left in the console or with GET /v1/account (usage_limit).

Limit	Default
A5S Async v1 jobs processing at once	5 (more are queued, first in first out)
A5S Async v1 jobs waiting in the queue	2,000
Transcript create requests	600 per minute
Maximum file duration / size	10 hours / 5 GB

Jobs beyond the processing limit wait as queued. Beyond the queue or request-rate limit you get 429 with a Retry-After header.

Limits are set per account. For pricing, higher usage limits or concurrency, access to a model, or a dedicated deployment, talk to sales.
