# Pricing

> How Breeze meters and bills Developer API requests.

Breeze uses credits shared across Studio and the Developer API. Each generation request consumes billable units based on text length, preview count, and generation type.

## How we meter

* Text to speech: per character after Unicode normalization.
* Voice design: per generated preview. When `preview_count` is omitted, Breeze generates one preview.
* Voice cloning: flat per-job cost.
* List, get, and delete catalog reads: not billed.

## Generation concurrency

Each plan includes a maximum number of simultaneous generations. A generation is admitted or running synthesis work. Paid plans also include a small queued generation buffer. Studio and Developer API jobs share the same per-user pool.

Sync text to speech, streaming text to speech, async text to speech, voice design, and voice cloning all count toward these limits. Voice design counts each requested preview as one generation.

| Plan    | Concurrent generations | Queued generations |
| ------- | ---------------------: | -----------------: |
| Free    |                      3 |                  0 |
| Starter |                      6 |                  2 |
| Creator |                     10 |                  3 |
| Pro     |                     20 |                  5 |
