## In brief
Inworld AI is a real-time AI infrastructure platform for voice and agents. The platform offers real-time text-to-speech, speech-to-text, an LLM router, and custom voices in a scalable credit model that goes well beyond gaming applications.

Paid plans include dollar credits for usage across the APIs. Starting with Creator, unused credits can roll over for up to 3 months while the subscription stays active. Higher plans also differ in usage rates, concurrency, and administration features.


## Limits
Credits are deducted by API product, model, and usage. Unused subscription credits can roll over for up to 3 months from Creator with an active subscription. For LLMs billed through Inworld, the current billing guide lists provider prices without markup. It does not specify a current BYOK surcharge.
