How Pricing Works

Pricing Units

  • to-imageCharged by USD/img, where "img" is the number of images, counted per image.
  • to-videoCharged by USD/sec, where "sec" is the video duration, counted per second.
  • to-speechCharged by USD/M chars, where "M chars" means one million input characters.

Parameter Variations

Some models use different prices based on input parameters. For example, certain video generation models have higher prices for generating 1080p videos compared to 720p videos.

Frequently Asked Questions

Are there any hidden fees?

No. Modellix uses transparent usage-based pricing. You pay based on the public model price and your actual usage.

How often do prices change?

Model prices may change when provider costs or model availability changes. The latest price is always shown on the pricing page and model detail pages.

How do volume discounts work?

For high-volume or long-term usage, Modellix may offer account-level top-up or credit discounts. Model prices remain based on the public pricing table.

Can I get a custom invoice?

Yes. For custom invoice requests, please contact us at support@modellix.ai and include your billing requirements.
