Calibrated · measured on the vendor's tokenizer · 2026-06-10 Auto-counts as you type

Counts use a chars-per-token calibration measured on the vendor's own published tokenizer (ByteDance-Seed/Seed-OSS-36B-Instruct, 2026-06-10). English prose is typically within a few percent; code and non-Latin scripts tokenize heavier. For billing-exact counts use the vendor's count-tokens API.

Q · 03 Does the price change for longer prompts? +
Tiered by input length and short-vs-long output length; this page uses the <=32K input plus long-output baseline tier. Short-output tier is CNY2/M output; this page shows the long-output baseline. The calculator on this page uses the listed baseline so cross-model comparisons stay consistent.

Q · 05 Are taxes or international region markups included? +
No. The source price is the Volcano Ark CNY token price before tax, enterprise contract terms, or deployment-region adjustments. USD conversion is stored only for AI//COST comparison pages.
Q · 06 How is the effective price calculated? +
AI//COST uses the same 92/8 agentic blend everywhere. With an 82% cache-hit rate, Doubao Seed 1.6's effective blended cost is $0.13/M.
