## Plans

SDK subscription tiers range from startup plans to enterprise agreements.

Each plan includes:

* Support for on-premise deployment
* A monthly allowance of processing minutes
* Access to all core SDK models

Enterprise options include:

* Custom audio evaluations
* Dedicated engineering support and onboarding
* Custom service-level agreements (SLAs)
* Offline or air-gapped licenses

Confirm the terms of these options in your agreement. See the [current pricing page](https://ai-coustics.com/pricing) for plan allowances and monthly or annual prices. Unused credits do not roll over to the next billing period.

<Info>
  SDK usage is measured by the duration of audio processed (not session uptime), with millisecond-level granularity.
</Info>

<Warning>
  **Usage is counted per model, not per stream.** If you run more than one model over the same audio, each model
  consumes its own minutes. A 10-minute call sent through voice activity detection (VAD) and an enhancement model deducts 20 minutes
  from your quota (10 for the VAD, 10 for the enhancement).
</Warning>

  </Accordion>

  <Accordion title="How is usage measured?">
    Usage is the duration of processed audio. If your application is open for 1 hour but processes 10 minutes of conversation, it uses 10 minutes of your quota.

    Each model counts the audio it processes. A 10-minute stream through two models, such as VAD and enhancement, uses 20 minutes. Any additional model, such as [Tyto](/models/audio-insight/tyto), adds its own usage.
