Specifications

Provider-documented facts. “Not collected” means we have not verified that field yet, not that the feature is unsupported.

Context / input limit
Not collected
Maximum input tokens
Not collected
Maximum output
Not collected
Reasoning
Not collected
Tool calling
Not collected
Structured output
Not collected

A fixed JSON response wrapper is not caller-defined structured generation.

Streaming
Not collected

API examples use polling followed by a finished audio file. Realtime marketing is not a documented streaming-audio protocol.

Batch processing
Not collected

An asynchronous request queue or a list of candidate songs does not establish a batch-discount API.

Fine-tuning
Not collected

Track editing and the term “fine-tune” in marketing do not establish customer model-weight training.

Context caching

No prompt-cache controls, cache lifetime, minimum or discounted cached price documented.

Input modalities
Musical tags and controlsSource for Input modalities (opens in a new tab)

Tag-driven composition; no general natural-language prompt or reference-upload contract is established.

Output modalities
MusicSource for Output modalities (opens in a new tab)
Output duration
Web: up to 5 minutes; API ceiling unverifiedSource for Output duration (opens in a new tab)

External concatenation of downloaded music is not native longer-track generation.

Output formats
M4ASource for Output formats (opens in a new tab)

Recommended and demonstrated API format, not an exhaustive enum. Web MP3/WAV exports are documented separately on the web-editor access record.

Generation controls
Select mood, genre, instruments and length; use the web editor for arrangement changes.Source for Generation controls (opens in a new tab)
Vocal generation
Not supportedSource for Vocal generation (opens in a new tab)

The current help article explicitly limits generation to instrumentals. A homepage mention of vocal stems “if any” does not establish a singing model.

Published training data
Provider reports training solely on music produced by its own team.Source for Published training data (opens in a new tab)

Provider claim, not an independent dataset audit or a guarantee against every copyright dispute.

Usage metering
Subscription plans with included requests or downloads; no text-token or per-question rate.Source for Usage metering (opens in a new tab)

Access & pricing

Prices belong to an endpoint and billing tier. A provider listing does not guarantee access for every account or region.

SOUNDRAW API

Provider source (opens in a new tab)
API model ID
Not collected

No public checkpoint selector. /api/v3 is a service route version.

Access
Published workflow uses authenticated POST generation and GET polling under https://soundraw.io/api/v3, returning request_id and status. The guide abbreviates operation paths; full documentation and credentials require signup. No authenticated calls or account creation performed.
Regions
No verified processing region; company location is not data residency.
Input modalities

Output formats
M4ASource for Output formats (opens in a new tab)

Recommended and demonstrated format; not an exhaustive format enum.

Required request fields
length in seconds is required; moods, genres, themes, tempo and file_format are optional.Source for Required request fields (opens in a new tab)

No minimum/maximum or complete enum is established by the example.

Asynchronous generation
SupportedSource for Asynchronous generation (opens in a new tab)
Response metadata
Request ID, processing status, then audio URL, editor link, BPM and returned duration.Source for Response metadata (opens in a new tab)
Output duration
Not collected

Public integration example is not a duration contract.

Output link expiry
Download links expire after 72 hours; the agreement says generated songs are then deleted from the server.Source for Output link expiry (opens in a new tab)

Not a guarantee that all account data, logs or backups are deleted on this schedule.

Request quotas
Not collected

The API agreement refers to limits notified to customers; no numerical request-rate ceiling published.

Usage metering
Starter: 100 successful song requests/month. Pro: 1,000. Further requests require consultation for a plan upgrade.Source for Usage metering (opens in a new tab)

Pro quota is documented in its separate agreement; errors do not count as successful generations.

Data & enterprise terms

Web terms and privacy policy apply. Plan-specific music-use rights must be reviewed separately from model access. No zero-retention or customer-data-training exclusion is inferred.

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 provider’s API agreement identifies proprietary algorithms and restricts deriving the service’s source code and algorithms. Its official training description identifies an in-house model, and its help center says generation requires the online service. One closed family record is supported; the exact underlying checkpoint count and architecture are not disclosed. Output music licensing is separate from weight availability.
