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.

Frequently asked.

Practical Doubao Seed 2.1 Turbo pricing questions, with original CNY rows preserved next to USD conversion.

Q · 01 What is Doubao Seed 2.1 Turbo priced at? +
Volcano Ark lists CNY 3/M input, CNY 0.6/M cache-hit input, and CNY 15/M output for the 0-256K row. At the catalogue's dated CNY reference rate that is $0.446/M input, $0.0893/M cached input, and $2.23/M output.
Q · 02 Is this the same page as Seed 2.1 Pro? +
No. Volcano Ark lists Turbo and Pro as separate API IDs with different price rows. AI//COST keeps Turbo on its own page so invoice checks do not mix the two tiers.
Q · 03 What cache hit rate does the effective price use? +
The effective tile uses the site-standard agentic blend with 92% input, 8% output, and an 82% prompt-cache hit rate, using the vendor cache-hit row.
Q · 04 Which source was used? +
The pricing source is the official Volcano Ark model price page, last verified on 2026-09-29. USD conversion uses the single dated CNY reference rate this catalogue applies to every yuan-priced model.
Q · 05 What is the context window? +
The published Turbo row is for the 0-256K input range, so AI//COST records this model with a 256K context label.
