Estimate your cost
Set your usage. Your estimate updates as you type.
Example: 6,000 input tokens for 10 pages, plus a 500-token summary. Page lengths vary; adjust the numbers below.
One run sends your input to the model once and receives an answer. Tokens are pieces of text: input is what you send, output is the answer you receive.

Watch out for
Knowledge cutoff is not published, and regional Model Studio terms can differ from other Qwen gateways. Confirm the exact endpoint, long-context pricing, output limit, logging, and retention settings.

How to choose
Compare the job, not the hype.
Start with the job you need to complete, then validate cost, access, and policy details on your exact provider route.
