How billing works
You pay per token. Three rates apply to each request: input for the tokens you send, cached for input tokens served from a prefix cache, and output for the tokens the model generates. Every figure in the table below is in USD per 1M tokens. Caching is automatic: Valar matches shared prompt prefixes for you and charges the lower cached rate on the tokens that hit. You can raise your hit rate by passingprompt_cache_key as a routing hint, but it’s optional.
The rate you pay also depends on the completion window you request. Faster scheduling carries a higher rate: the on-demand Now window costs the most, Priority about 25% less, Standard about 50% less, and Flex the least. The table prices out the windows available for each model; coverage varies, and you can mix windows per request. Completion Windows explains the trade-offs.
Window coverage differs by model, and we keep adding models and widening window support. If a model or window you want isn’t shown, get in touch.
