Estimate · doubao-tokenizer-estimate · ≈3.85 chars/token Auto-counts as you type

This is a chars-per-token approximation, not a real tokenizer. Actual tokens vary by language, code density, and tool-call overhead — counts are typically ±10–20% off for English prose, more for code or non-Latin scripts. For exact billing, use the vendor's official tokenizer.

Frequently asked.

Practical Doubao pricing questions, including CNY conversion, context tiers, cache hits, and regional tax caveats.

Q · 01 What is Doubao Seed 2.0 Pro priced at? +
Doubao Seed 2.0 Pro's <=32K tier is listed at ¥3.2/M input, ¥16/M output, and ¥0.64/M cache-hit input. AI//COST stores that as $0.451/M, $2.254/M, and $0.09/M using ¥7.1/USD.
Q · 02 Does the price change for longer prompts? +
Yes. Volcano Ark lists Doubao prices by input length tiers, with higher rates above 32K and again above 128K for Seed 2.0 models. This page uses the <=32K baseline tier and calls out the tiering in notes.
Q · 03 How does context caching work? +
The pricing table lists a cache-hit input rate of ¥0.64/M, converted here to $0.09/M. The calculator defaults to an 82% cache-hit workload for agentic reuse patterns.
Q · 04 Are taxes or international region markups included? +
No. The source price is the Volcano Ark CNY token price before any tax, enterprise contract, or regional deployment adjustments. USD conversion is stored only for AI//COST comparison pages.
Q · 05 How is the effective price calculated? +
AI//COST uses the same 92/8 agentic blend everywhere. With an 82% cache-hit rate, Doubao Seed 2.0 Pro's effective blended cost is $0.32/M.
Q · 06 Is this an OpenAI-compatible API? +
Volcano Ark exposes Chat Completions-style model serving for Doubao models. Parameter support varies by model and deployment mode, so production integrations should verify function calling, Responses API, and cache behavior in the Volcano console.
