Model comparison
Compare MiniMax H3 Max and Grok Imagine Video 1.5 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.
SpaceXAI's current video model for turning text, images, or references into short clips with optional generated speech and sound.
Reference-to-video output is capped at 720p, generated download URLs are temporary, and complex requests can take several minutes to complete.
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 | Grok Imagine Video 1.5 |
|---|---|---|
| Generation priceCurrent list price per generated second or the provider's closest billing unit. | $0.05 480p · $0.08 768p · $0.16 1080p / sec | $0.08 480p · $0.14 720p · $0.25 1080p / sec |
| Clip durationDocumented duration choices or maximum clip length. | 5–15 seconds | 1–15 seconds |
| Maximum outputHighest provider-documented output resolution, with relevant constraints. | 1080p latent refinement; 768p native | 1080p; references capped at 720p |
| Native audioWhether the endpoint generates synchronized audio with video. | Yes | Yes; can be disabled |
| Input modesSupported text, image, video, reference, or motion inputs. | Text, first/end image, or image/video/audio references | Text, image, or references 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 | Typically up to several minutes |
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.
SpaceXAI says API inputs and outputs are not used for training without explicit permission. Default encrypted retention is 30 days; team-level zero data retention is available with feature tradeoffs.
