How billing works
The service uses a prepaid USD balance. You top up your balance, and usage is charged per request based on the actual tokens consumed by the model you choose. There are no subscriptions and no monthly fees. Balance never expires and is non-withdrawable (see Terms of Service).
Paid models are pay-as-you-go: usage is charged against your prepaid USD balance at the rates below. A limited free tier is also available — see “Free tier” below.
Top-up amounts

DeepSeek models: rates may be higher during peak hours (weekdays 01:00–04:00 and 06:00–10:00 UTC), in line with the upstream provider's peak pricing. Published rates include a service margin over upstream costs and may be adjusted when upstream costs change; changes are announced in the app before they take effect. The in-app model list always shows the current rates.
Free tier
The free tier is powered by third-party free quotas (Google Gemini, Groq and Cloudflare Workers AI). Each user gets one shared daily allowance across all free models — both a token limit and a request limit apply, the allowance is shared across the three providers, switching models does not reset it, and it resets the next day.
Free-tier requests are screened only by a basic local content filter; they do not receive the content moderation applied to paid models. Gemini free-tier usage is subject to Google's free-tier terms, and content may be used by Google to improve its products — please do not submit sensitive information on the free tier. Users in the EEA, Switzerland and the United Kingdom cannot use the Gemini free option (the other two providers are unaffected).
When the daily allowance is used up, top up your balance to use any of the paid models listed above.
