arkennemasis fal · MiniMax H3 Max Turbo Text to Video · $0.025-0.08/s
fal's H3 Max Turbo is a post-trained variant of MiniMax H3, tuned for stronger prompt adherence and better aesthetics while co-optimized with our custom inference stack for higher throughput with no compromises on output quality Pricing (from fal, 2026-09-30): Video costs $0.0125 per second at 480p, $0.02 per second at 768p, and $0.04 per second at 1080p. Note: these are promotional launch rates, 50% off for a limited time. The discount ends September 30, after which 480p is $0.025/second, 768p is $0.04/second, and 1080p is $0.08/second.

Inputs (12)
| Name | Type | Default | Description |
|---|---|---|---|
| prompt | STRING | Text prompt for video generation | |
| duration | INT | 55–15 | The duration of the video in seconds. |
| resolution | COMBO | 768P | The native generation resolution, or 1080P latent refinement from a native 768P source. |
| seed | INT | -1-1–2147483647 | Random seed. A random seed is selected when omitted. -1 leaves it to the model. |
| enable_safety_checker | BOOLEAN | true | If set to true, the safety checker will be enabled. |
| prompt_expansion_mode | STRING | balanced | How much effort to spend rewriting the prompt before generation. 'disabled' skips prompt expansion. 'balanced' returns in about a second. 'quality' spends up to ~30s on a richer prompt. |
| aspect_ratio | COMBO | 16:9 | The aspect ratio of the generated video. |
| target_audioopt | AUDIO | Optional URL of an audio clip at least 2 seconds long (maximum 15 MB) to pin to the generated soundtrack. Longer clips are trimmed to the requested video duration, keeping the beginning. The original audio replaces the output soundtrack, padded with silence if shorter than the video, without changing playback speed. Exceptionally high sample rates may be resampled to 96 kHz. Accepts an HTTP(S) URL or a base64 data UR | |
| max_cost_usdopt | FLOAT | 20.00–100000 | Safety cap. If the estimated cost of this run is above this many US dollars the node stops BEFORE sending anything to fal. 0 = no cap. |
| reuse_identical_runopt | BOOLEAN | true | If these exact inputs (the settings AND the same pictures/clips/audio) were already paid for and the files are still in output/fal, return them instead of paying again - also after a ComfyUI restart. Turn off for a fresh take with the same settings. |
| extra_jsonopt | STRING | Advanced: a JSON object merged into the request last, for any fal field this node has no box for. Example: {"seed": 7}. Leave empty normally. | |
| max_concurrentopt | INT | 11–32 | How many paid fal calls may run at the same time in one run, across every fal node. 1 (default) = one after another. This node starts its paid part only while fewer than this many fal calls are running. Once any fal node fails, the ones still waiting are not started, so nothing more is billed. |
