Please see our Pricing Page for more details about each plan, including model pricing, available features, and rate limits. Paid plans include credits equal to the plan price each billing cycle. Unused credits on Developer, Growth, and Enterprise plans roll over for up to 3 months with an active subscription. Your credit balance is displayed at the top of the Billing page. Credits are consumed by API and Playground usage across all products (TTS, STT, LLM Router, Realtime). You can upgrade your subscription at any time, and any unused credits from your previous plan will be credited to the new one. Any outstanding unpaid usage at the time of upgrade will be immediately charged. If you need more credits than provided in your selected plan, you can:
  • Add credits — Click Add credits to purchase more. The minimum purchase is $10. You will be redirected to a secure checkout page, and credits are applied immediately upon payment.
  • Auto-reload — Enable auto-reload to automatically purchase credits when your balance falls below a threshold you set. Configure the reload amount and threshold from the Billing page.
Enterprise accounts are billed per their agreement. Credit purchases are not available for enterprise plans.
To downgrade your plan or unsubscribe, please email support@inworld.ai.
