The model this site actually runs, what is only available upstream, and the sources we verified — so you can check them yourself.
- Model used here
- MiniMax H3 Max Turbo — fal's post-trained variant of MiniMax H3, served through fal.ai's minimax/h3-max-turbo text-to-video and image-to-video endpoints.
- Naming
- MiniMax H3 is the open-weight base video model. H3 Max is fal's post-trained variant. H3 Max Turbo is fal's higher-throughput variant. All three are video models — unrelated to any language model.
- Resolution
- 480P and 768P, both native. The base H3 also offers 2K/4K upscales of a 768P render; H3 Max and H3 Max Turbo do not.
- Duration
- 5–15 seconds at 24 FPS (fal's H3 Max Turbo endpoints; the open-weight H3 model card lists 4–15 seconds).
- Aspect ratios here
- 16:9, 9:16, 1:1, 4:3, and 3:4. The upstream schema also lists 21:9, which this site does not expose.
- Audio
- Native audio is generated together with the video, so sound and picture stay in sync.
- Image input
- Paste a public image URL (used as the first frame). The upstream endpoint also accepts an optional last frame via end_image_url — not exposed in this site's UI.
- Reference-to-video
- Available upstream on H3 and H3 Max (H3 Max's reference endpoint arrived after its launch). This site does not offer a reference-to-video mode.
- Generation speed
- Vendor-reported only. fal's API returns a timings.inference field (backend denoising time); end-to-end wait adds queueing, prompt expansion, and delivery. This site runs no latency benchmark of its own.
- Weights
- H3 has open weights (33B parameters, MiniMax H3 Community License). H3 Max and H3 Max Turbo list no separate weights release — API only.
