Model comparison
Compare MiniMax H3 Max and Runway Gen-4.5 using the same provider-sourced video generation rubric. No mystery score and no invented benchmark ranking.
Facts checked September 14, 2026
Set your usage. Your estimate updates as you type.
Example: 8-second, 720p clips with audio. Models that do not support these settings will not receive an estimate.
Estimates exclude taxes, tools, cache storage/writes, free allowances and custom discounts. Image estimates cover output only, not prompt or reference-image charges. Quality modes differ by model. Unlisted settings are not treated as free.

Quick take
fal's speed-focused post-trained version of MiniMax H3 for short video with native audio, fast 768p iteration, and text, image, or multimodal reference input.
fal's roughly 2.46-second figure is backend inference for one five-second 768p test—not total wait time or an SLA. H3 Max is hosted by fal, its weights are not published, 1080p is refined from the native 768p path, and reference media can add meaningful token cost.
Runway's flagship developer video model for text- and image-guided clips, with professional formats and a predictable credit-per-second base rate.
Format surcharges can exceed the base generation cost, and the provider does not publish one render-time number across settings.
Compare the published facts
Values use each provider's own published units and limits. A blank means the provider did not publish a directly comparable value in the sources reviewed.
| Video generation | MiniMax H3 Max | Runway Gen-4.5 |
|---|---|---|
| Generation priceCurrent list price per generated second or the provider's closest billing unit. | $0.05 480p · $0.08 768p · $0.16 1080p / sec | 12 credits / sec = $0.12 / sec |
| Clip durationDocumented duration choices or maximum clip length. | 5–15 seconds | 2–10 seconds |
| Maximum outputHighest provider-documented output resolution, with relevant constraints. | 1080p latent refinement; 768p native | Endpoint and output-format dependent |
| Native audioWhether the endpoint generates synchronized audio with video. | Yes | No native audio listed |
| Input modesSupported text, image, video, reference, or motion inputs. | Text, first/end image, or image/video/audio references | Text or image to video |
| Generation timeOnly shown when a provider publishes a range; not a Cody benchmark. | fal test: ~2.46s inference for a 5s 768p clip | Not published |
How to choose
Start with the job you need to complete, then validate cost, access, and policy details on your exact provider route.
fal stores request inputs and outputs by default. The X-Fal-Store-IO: 0 header prevents payload storage, but separately uploaded CDN inputs can remain accessible and need their own deletion or lifecycle handling.
Data handling depends on the Runway plan and agreement. Review Runway's current terms, workspace controls, and any enterprise commitments before processing confidential media.
