Reasoning

Tool calling

Structured output
Not collected

A JSON envelope containing an audio file does not establish caller-defined structured generation.

Streaming
Not collected

The retained APIs describe completed audio files; queue logs are not streaming audio.

Batch processing
Not collected

An asynchronous generation queue does not establish a batch-discount API.

Fine-tuning
Not collected

B2B model licensing does not by itself establish customer fine-tuning support.

Parameters

Architecture
Diffusion-based generationSource for Architecture (opens in a new tab)

Both fal descriptions identify diffusion models. Parameter count and exact checkpoint topology are undisclosed.

Languages

Context caching
Not collected

No model-specific cache control, TTL, minimum or discounted cached rate documented.

Input modalities
TextSource for Input modalities (opens in a new tab)

Documented music/SFX generation APIs accept text. Website-level multimodal marketing does not establish a direct multimodal Maestro endpoint.

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

Music and sound effects. No standalone TTS, transcription or singing capability is inferred.

Output duration
Music up to 150 seconds; sound effects up to 35 secondsSource for Output duration (opens in a new tab)

Documented fal-era ceilings; current B2B contract limits must be confirmed separately.

Audio sample rates
44.1 kHzSource for Audio sample rates (opens in a new tab)

Documented fal music and SFX schemas; not a guarantee for every private deployment.

Audio channels
StereoSource for Audio channels (opens in a new tab)

Both documented fal schemas describe stereo output.

Output formats
WAVSource for Output formats (opens in a new tab)

Both fal schemas expressly describe WAV audio. Generic File PNG examples are irrelevant.

Published training data

Caching

Caching can reuse earlier input processing. Availability, lifetime and billing depend on the endpoint. A cache hit still generates a new response.

01 / INITIAL INPUTProcess & retain

The system processes eligible input and retains reusable state.

02 / LATER REQUESTCheck available state

Reuse depends on matching input, session state and the cache policy.

03 / CACHE HITReuse & generate

Reusing state can reduce repeated work. Any charges follow the billing rules below.

What the measurements say

No benchmark observations have been added for this model. We do not turn a vendor description into a performance score.

Latency and throughput depend on the host, request size, reasoning settings and load. There is no measured speed or global usage figure in this record.

The record behind the model

Why it is included

The developer’s founder explicitly calls Maestro proprietary and says its intellectual property remains with Beatoven Private Limited for commercial/enterprise licensing. The official fal launch also identifies it as proprietary. One family record covers music and SFX operations; separate checkpoint counts, public weights and independently versioned variants are not asserted.
