Understand prices, multipliers, and actual charges

Pricing formula

Platform input = official input USD / 1M tokens × CNY 1 × group multiplier
Platform output = official output USD / 1M tokens × CNY 1 × group multiplier
Official CNY reference = official USD number × approximately CNY 7

If the official input number is USD 5 and the group multiplier is 1x, 懂api displays CNY 5 per 1M tokens; the official CNY reference is approximately CNY 35.

Each billing dimension is calculated separately

Grok image and video billing

Grok images are billed per image: each image costs the configured base price times the group multiplier. Grok videos follow the live catalog price_unit: second charges the base rate for the selected mode and resolution × submitted duration × the current group multiplier. Single-image and 2–4-image generation use their image-generation rate; reference images carry no separate count fee. Version 1.5 without images uses the text-only rate. 1080p requires version 1.5 with reference images. Base rates and group multipliers remain separate; discounts never rewrite the base rate. Grok second rates follow the platform pricing rule: the USD numeric rate forms the CNY base at 1 USD = 1 CNY, then the group multiplier applies once. The official CNY reference uses approximately 1 USD = 7 CNY for comparison only. For example, a base rate of CNY P per second for 8 seconds at multiplier 0.6 costs P × 8 × 0.6 = 4.8P CNY; the current rate of each mode and resolution is on the Grok model page. Mode, resolution, duration, and rate freeze at submission and appear in Usage logs. Models still marked request and historical tasks retain their original per-request contract. The live model catalog is authoritative for currency and current prices.

Seedance 2.5 video billing

Seedance 2.5 models named with 480p, 720p or 1080p are billed per second by Volcengine Ark's official rules at the official CNY prices:

• Without reference video (text, reference images, reference audio): the no-video price × output seconds × your group ratio.
• With reference video: the with-video price × (output seconds + total reference video length) × your group ratio; reference videos count at their actual length, and a total under 4 seconds counts as 4 seconds.

Example: a 5-second 720p output with a 6-second reference video at group ratio 1 costs 0.9072 × (5 + 6) = CNY 9.98. Mode, resolution, seconds, reference video length and price freeze at submission and appear in Usage logs; a reference video that cannot be read rejects the request before any charge, and failed generations are refunded. Models named with a duration (such as -30s) are billed per request. Parameters and media requirements are in the API reference; the live model catalog is authoritative for current prices.

Why group prices differ

A group quote exists only when an enabled channel supports the model, the group is available to the user, and the group has a valid public multiplier. Unsupported model/group pairs are omitted.

Verify the actual charge

1. Open Usage logs and filter by request ID, model, or time.
2. Check final status, input/output tokens, cache dimensions, and charged amount.
3. For smart routing, the selected concrete token group is recorded in request details.

Use Models for pre-call comparison and Usage logs for post-call settlement.

Overview and log statistics

The overview defaults to today with hourly aggregation. Wallet/lifetime usage, filtered usage, and platform totals have separate scopes. Log charge summaries follow the selected log type and filters. Error logs describe failed attempts; a summary amount does not prove a failed request was charged. Check the final result and charge for the same request ID. See Overview statistics.
