Do MiniMax H3 Reference Images Cost Extra?

Overview

It depends on the provider’s pricing policy, so do not assume either way — confirm it on the route you use before building reference-heavy workflows. Some platforms include reference inputs in the base generation price, while others treat certain inputs or higher input counts as an add-on that shows up on the bill.

The reason to check is that reference-guided generation, which is one of the model’s strengths, can quietly become a cost driver if each reference or each extra image carries a fee. At low volume the difference is negligible; across thousands of generations a small per-reference charge adds up to a real line item. It also interacts with quality: if references cost extra, the “use a few clean references, not many noisy ones” advice happens to be the cheaper path too, which is a rare case where quality and budget point the same way.

Read the rate card for exactly what counts as a billable input — images, video, audio, and any count thresholds — rather than assuming all references are treated alike.

Then include references in your cost-per-usable-clip test at your real settings, so the figure you plan around reflects the workflow you will actually run, not a bare text-to-video baseline.
