Model Pricing

Usage Cost

$0.0023 Cost Per Seconds

Cost Per Seconds refers to a pricing model where the total cost is calculated based on the number of seconds the model uses GPU time. In this system, the longer the model runs (measured in seconds), the higher the cost, making it directly proportional to the actual compute time required.

Features Included:

  • Full API access
  • Web UI usage
  • Output in multiple formats
  • Commercial usage rights

Note: Pricing is subject to change. For bulk usage or custom packages, please contact us.
