Pricing that scales with you

Credits are a dollar-denominated balance used to pay for usage across all Inworld products. When you subscribe to a paid plan, you receive credits equal to your plan price at the start of each billing cycle. For example, the Developer plan ($300/mo) grants $300 in monthly credits. As you use Inworld products, usage is metered and deducted from your credit balance at your tier's rates. Higher tiers unlock lower per-unit rates and higher rate limits across various features/products.

LLM Inference bills per token from the same credits as every other product. Open models we host, such as Gemma 4, GLM and DeepSeek, start at $0.07 per 1M input tokens, and cached input costs up to 99% less. Every model's rates are on the models page.

Unused subscription credits roll over automatically for up to 3 months, as long as you have an active paid subscription and a plan of equal or higher value. Each month's credit grant has its own 3-month window before it expires. For example, if you have $50 unused from January, that $50 expires at the end of March.

You can purchase additional credits or enable auto-reload to automatically add credits when your balance drops below a threshold you set. These credits are billed at your current tier's rates and expire after 1 year from purchase. They are not subject to monthly expiration or rollover limits.

Your upgrade takes effect immediately and starts a new billing cycle: you are charged the full price of your new plan, and then that amount every month (or every year on an annual plan) until you cancel. Usage already metered on your old plan is settled from your existing credit balance, or billed at the end of that plan's cycle. It is not added to the upgrade charge. Unused credits carry over to your new balance and keep their original 3-month expiry. Downgrades and cancellations take effect at the end of your current billing period, at which point any remaining credits are forfeited.
