# unlimited

> unlimited generation with a concurrency capacity that fits your needs.

## how unlimited works

this plan gives you unlimited text-to-speech generation and unlimited silk
agents. you choose a concurrency capacity (the number of requests silk can
process simultaneously) and your plan includes that capacity every month.

there is no published minute allowance and no normal-use slowdown after a
hidden threshold. silk records generated audio duration for operations and
usage visibility, never to calculate an unlimited customer's bill.

for unlimited customers, the **usage** dashboard shows:

* **purchased lines:** your selected concurrency capacity
* **active lines:** agent sessions currently starting or running
* **failed requests:** recent rejected or failed requests, with their http
  error codes

capacity belongs to the account and is shared by mulberry, muga, agents, api
keys, projects, and voices. a request or agent session releases its slot when
it completes, fails, times out, or is cancelled.

upgrades take effect immediately with the provider's prorated adjustment.
downgrades and cancellation take effect at renewal; neither changes your api
keys or account configuration. each renewal is charged on the provider cycle
date, not on a fixed 30-day approximation.
