Not collected

A JSON response containing a video file is not constrained JSON Schema generation.

Streaming

Not collected

Queue status/log streaming is not incremental video output.

Batch processing

Not collected

Queued requests do not establish a Batch Inference API.

Fine-tuning

Not collected

Public base weights and a public realism LoRA do not establish fine-tuning support for Max or Max Turbo.

Context caching

Not collected

No documented prompt-cache controls, rates, minimum input or lifetime for these endpoints.

Maximum prompt characters

50,000Source for Maximum prompt characters (opens in a new tab)

fal API prompt limit; MiniMax native Max has a separate 7,000-character limit.

Output modalities

Video, AudioSource for Output modalities (opens in a new tab)

Synchronized video audio does not establish a standalone speech or music API.

Output resolutions

480P, 768P, 1080PSource for Output resolutions (opens in a new tab)

480P/768P native; 1080P latent refinement of a 768P source. MiniMax native Max supports only 480P/768P.

Video duration

0.92–15 seconds; fractional durations acceptedSource for Video duration (opens in a new tab)

fal request duration defaults to 5 seconds; actual output may be about 0.7 seconds longer. Use at least two seconds with target_audio_url.

Base model

MiniMax H3 open-weight base; post-trained by fal ResearchSource for Base model (opens in a new tab)

Input modalities

Text, AudioSource for Input modalities (opens in a new tab)

Required request fields

Non-empty prompt and prompt_expansion_mode are marked required. Expansion defaults to balanced in property metadata, but callers should provide it explicitly.Source for Required request fields (opens in a new tab)

Prompt expansion

disabled, balanced or quality; balanced is the declared default. Approximate expansion times are about one second or up to thirty seconds, not an end-to-end SLA.Source for Prompt expansion (opens in a new tab)

Random seed

Optional integer; omitted means random. Bounds are not specified.Source for Random seed (opens in a new tab)

Safety checker

enable_safety_checker defaults to true.Source for Safety checker (opens in a new tab)

Output transport

sync_mode=false returns a CDN URL; true returns Base64. This changes file transport, not whether inference is synchronous.Source for Output transport (opens in a new tab)

Timing measurements

timings.inference measures DiT denoising only, excluding the rest of the request. expanded_prompt may be null if unchanged, disabled or handled by the MiniMax hosted API.Source for Timing measurements (opens in a new tab)

Asynchronous generation

SupportedSource for Asynchronous generation (opens in a new tab)

Submit via queue.fal.run and poll the returned status/result URLs.

Cancellation and task deletion

Queued cancellation removes a request; in-progress cancellation signals the runner and may not stop execution.Source for Cancellation and task deletion (opens in a new tab)

Concurrent requests

Account-wide across endpoints: new accounts start at two concurrent running requests; self-serve capacity scales to forty with paid-invoice history. Per-model limits and enterprise allocations can differ. Inspect the account dashboard for actual capacity.Source for Concurrent requests (opens in a new tab)

Input media transport

Public URLs without required cookies/auth, presigned URLs, Base64 data URIs or SDK uploads. File uploads are public by default unless access controls are configured.Source for Input media transport (opens in a new tab)

Output link expiry

CDN lifecycle can be set at account or request level, including X-Fal-Object-Lifecycle-Preference. No universal output URL lifetime is assumed.Source for Output link expiry (opens in a new tab)

Soundtrack replacement

Optional HTTP(S)/Base64 audio, at least two seconds and at most 15 MB; requested output must be at least two seconds. Replaces the soundtrack, trims from the end or pads silence without changing playback speed. Exceptionally high input sample rates may be resampled to 96 kHz.Source for Soundtrack replacement (opens in a new tab)

Aspect ratios

21:9, 16:9, 4:3, 1:1, 3:4, 9:16Source for Aspect ratios (opens in a new tab)

Defaults to 16:9.
