What a request actually costs

A worked example: a 10,000-token prompt where 8,000 tokens hit the cache, which produces 2,000 output tokens.

Component	Tokens	Rate per 1M	Cost
Fresh input	2,000	$1.5086	$0.0030172
Cached input	8,000	$0.1886	$0.0015088
Output	2,000	$4.5257	$0.0090514
Total	12,000	—	$0.0135774

Rates shown to six decimals so the arithmetic adds up; the catalogue page rounds them for display. Cached tokens are only billed at the cache rate when the provider serves a prompt prefix from its cache.

The same request without cache hits would cost $0.0241374 — caching is what makes long, repeated system prompts affordable.

Compliance

Two facts to check before you send production traffic.

!DeepSeek models are restricted for U.S. federal use

Under the FY2026 National Defense Authorization Act (§1532 and §6604) and the U.S. Department of Homeland Security directive issued in October 2026, U.S. federal civilian agencies, the Department of Defense, the Intelligence Community and their contractors may not procure or use DeepSeek technology — including through third-party services such as this one, and regardless of whether the model is self-hosted. Several states, including New York, Virginia, Tennessee and Texas, have imposed comparable restrictions on government devices and networks.

If you are a U.S. federal agency, a federal contractor, or a state or local government entity, do not use the DeepSeek models offered here. Other models in the catalogue are not covered by this restriction. This notice is provided for compliance convenience and is not legal advice; you remain responsible for your own regulatory position.

iWhere your data is processed

Every model in this catalogue is operated by a provider whose inference infrastructure is located in mainland China. When you call a model, the content of your request is transmitted to that provider and processed there, and the response is returned to you. Account and billing data are stored in the United States and the European Union.

We do not use your prompts or outputs to train models. If your workload cannot leave a particular jurisdiction, contact support@adzukiai.com before sending production traffic.

Qwen-3.8-Max questions

Cost, caching and jurisdiction — the three things people ask first.

Does prompt caching reduce the cost of Qwen-3.8-Max?

Yes. Cached input is $0.19 per million tokens against $1.51 for fresh input, roughly 8× cheaper. Caching only applies when the provider serves a prompt prefix from its cache; the first request that populates the cache still pays the full input rate.
