Реальный биллинг Seedance 2.0: почему нет фиксированной цены за секунду

Реальный биллинг Seedance 2.0: сначала output tokens, затем расчет цены за секунду#

Клиенты часто спрашивают: сколько стоит Seedance 2.0 за секунду? Точный ответ: это не фиксированная цена за секунду. Итоговая стоимость считается по фактическим output tokens, которые возвращает провайдер после завершения задачи.

Главный вывод#

The correct billing flow is:

submit task -> task completes -> upstream returns usage tokens -> calculate USD by tokens -> convert to Crazyrouter quota

It is not:

submit task -> charge directly by requested duration seconds

So we should not say:

1 second = fixed N tokens

Instead, after the task finishes, we can calculate:

observed tokens/sec = billedTokens / requestedDurationSeconds
observed USD/sec = actualPriceUSD / requestedDurationSeconds

This is an observed value for that task, not a universal fixed rate.

Текущие публичные ограничения#

Current public capability boundary for doubao-seedance-2-0 and doubao-seedance-2-0-fast:

• 480p supported
• 720p supported
• 1080p is not currently in the public supported range

The measured examples below use 720p and 4s.

Правила биллинга#

Seedance 2.0 billing mainly depends on whether the request contains video input.

video0 means there is no video reference input. video1 means the request includes video reference input, such as reference_video.

Формула итоговой стоимости#

After a successful task, the system first reads TotalTokens. If unavailable, it falls back to CompletionTokens.

actualPriceUSD =
  unitPriceUSDPer1MTokens
  * (billedTokens / 1_000_000)
  * quantityMultiplier
  * groupRatio
  * discount

Without extra multipliers or discounts:

actualPriceUSD = unitPriceUSDPer1MTokens * billedTokens / 1_000_000

Crazyrouter quota conversion:

actualQuota = int(actualPriceUSD * QuotaPerUnit)
QuotaPerUnit = 500000

Тест 1: text-to-video#

Request profile:

• Model: doubao-seedance-2-0
• Type: text-to-video
• Input: text only, no image or video reference
• Resolution: 720p
• Duration: 4s
• Task ID: cgt-20260617212928-5s755
• completion_tokens = 87300
• total_tokens = 87300

Because there is no video reference input, the billing key is:

billing_key = doubao-seedance-2-0:video0
unitPrice = 46 / 7 = 6.571428 USD / 1M tokens

Calculation:

tokensPerSecond = 87300 / 4 = 21825 tokens/s
actualPrice = 87300 / 1000000 * 6.571428 = 0.5736 USD
pricePerSecond = 0.5736 / 4 = 0.1434 USD/s

Result: this simple 4-second 720p text-to-video task was observed at about $0.14/sec.

Тест 2: generation по reference video#

Request profile:

• Model: doubao-seedance-2-0
• Type: reference-video generation
• Input: text + previous generated video as reference_video
• Resolution: 720p
• Duration: 4s
• Task ID: cgt-20260617214300-rsnsx
• completion_tokens = 173700
• total_tokens = 173700

Because the request contains video reference input, the billing key is:

billing_key = doubao-seedance-2-0:video1
unitPrice = 28 / 7 = 4.000000 USD / 1M tokens

Calculation:

tokensPerSecond = 173700 / 4 = 43425 tokens/s
actualPrice = 173700 / 1000000 * 4.000000 = 0.6948 USD
pricePerSecond = 0.6948 / 4 = 0.1737 USD/s

Result: this 4-second 720p reference-video task was observed at about $0.17/sec.

Сравнение двух тестов#

This comparison shows why a single per-second price is misleading: video-input requests have a lower unit token price, but may return more tokens, so the final observed per-second cost can still be higher.

Объяснение для клиента#

У Seedance 2.0 нет единой фиксированной цены за секунду. Биллинг идет по фактическим output tokens после завершения задачи. Можно посчитать наблюдаемую среднюю цену за секунду по готовым задачам, но универсального фиксированного tokens/sec нет.

If customers ask why there is no fixed second price, the reason is simple: duration is a task parameter, but the final billing unit is the actual output tokens returned after generation.

Внутренняя рекомендация#

To give customers more stable estimates, collect more real task samples and group them by:

• text-to-video without reference input
• image-to-video
• reference-video generation
• with or without audio
• duration
• prompt complexity
• resolution

Then calculate p50, p75, and p90 tokens/sec. This is much more reliable than guessing a universal tokens/sec number.

Bottom line#

Самое безопасное объяснение клиенту: Seedance 2.0 оплачивается по фактическим output tokens. В текущих тестах 720p/4s простой text-to-video стоил около $0.14/s, а generation с reference video — около$0.17/s.
