How to read these options
These are starting paths, not subscription tiers. Free models have a published zero token price; keys and rate limits still apply. Platform fees, taxes, refunds and enterprise contract terms are not published on this page. Check billing records and the applicable terms before funding an account.

Frequently asked questions
What do the model prices include?
The table shows reference input and output rates from the CLSSAI catalog, in USD. Provider-specific rates, cached tokens, long-context tiers and media billing can differ. Open a model to inspect its provider prices.
How is an API request charged?
When the provider reports a valid request cost, that amount is used for billing. Otherwise, charges follow the configured price table. Reasoning and thinking tokens count as output. See the billing guide for the exact rules.
Are free models completely unrestricted?
No. A zero token price does not remove API key requirements or rate limits. Media generation is not considered free just because a token-price field is zero.
Why does my balance update after the response?
Settlement is asynchronous. Consumption and remaining balance can lag completed requests by several minutes. Use the balance and usage records to reconcile charges.
How do team keys share a balance?
A shared child key uses its parent’s balance. An allocated child key has its own funded balance. The credits page separates allocations from consumption.
