This topic describes the billing rules and prices for model training in Alibaba Cloud Model Studio.

Model training billing

Video generation models - Wan

Note

For more information about the model training process, see Fine-tune a video generation model. After the training is complete, first deploy the model before you can call it.

Billing method	Billed by the number of training tokens
Billing formula	Model training fee = Total training tokens × Training unit price (Billing unit: per 1,000 tokens)

Formula for calculating total training tokens

$T r ainin g T o k e n s T o t a l = (i = 1 \sum N B i ll in g D u r a t i o n o f Vi d e o_{i}) \times \frac{ma x _ p i x e l s}{1024} \times n_e p oc h s$

Where:

N: The total number of videos in the training set.
max_pixels: A hyperparameter that specifies the maximum number of pixels for a video. You can configure this parameter when you create a fine-tuning job.
n_epochs: A hyperparameter that specifies the number of training loops. You can configure this parameter when you create a fine-tuning job.
Billable duration of a single video: The billable duration of a single video is calculated by rounding its original duration in seconds to the nearest integer. The final billable duration is then capped by the model's limits.
- wan2.5 model: billable_duration = min(10, rounded_duration). This means that a single video is billed for a maximum of 10 seconds.

Billing example

Assume that you fine-tune the wan2.5 model. The training set contains two videos with durations of 3.4 seconds and 11.5 seconds. The parameters are set as follows: max_pixels = 36,864, n_epochs = 400, and the training price is $0.05 per 1,000 tokens.

Duration calculation:
- Video 1: 3.4 seconds is rounded to 3 seconds. Billable duration = min(10, 3) = 3 seconds.
- Video 2: 11.5 seconds is rounded to 11 seconds. Billable duration = min(10, 11) = 10 seconds.
- Total billable duration = 3 + 10 = 13 seconds
Total training tokens = 13 × (36,864 / 1,024) × 400 = 187,200 = 187.2 thousand tokens
Model training fee = 187.2 × 0.05 = $9.36

Service	Model	Training price (per 1,000 tokens)
Image-to-video - first frame	wan2.5-i2v-preview	$0.05

FAQ

Q: Am I charged if I cancel model training?

A: Yes. You are charged for the resources that have already been used if you manually cancel a training job. However, you are not charged for training jobs that are interrupted for other reasons.

Q: How do I view invocation statistics for a deployed model?

A: You can view invocation statistics on the Model Observation page.
