Music controls

Musical brief, instrumental mode, generated lyrics or supplied lyricsSource for Music controls (opens in a new tab)

The beta web interface exposes these controls. They do not establish model fine-tuning or a native structured-output API.

Web input limits

5,000-character counter shown in the creation editorSource for Web input limits (opens in a new tab)

Website input guidance, not a token context window or a verified underlying API hard limit.

Web song count

1–4 songs shown in the count menu; 3 and 4 carry membership badgesSource for Web song count (opens in a new tab)

Two songs is the displayed default. Multiple outputs are not evidence of a discounted batch-inference API. Membership price and quota are unverified.

Published price

Website uses creative credits; per-track debit and cash conversion unverifiedSource for Published price (opens in a new tab)

Promotional signup and daily-login credits do not establish a permanent free plan or a USD-per-song rate.

Data retention

Web policy retains personal data while needed for the service or legal obligations, sometimes beyond account deletion. No fixed general retention interval is specified. This is the product-specific web policy, not Model Studio API retention.Source for Data retention (opens in a new tab)

Web product content-use policy

Terms permit model development using non-personal user content and grant a broad content licenseSource for Web product content-use policy (opens in a new tab)

Web product retention

Purpose-based retention with legal exceptions; no fixed general periodSource for Web product retention (opens in a new tab)

The linked HappyShrimp policy contains an apparent cross-product URL reference to happyoyster.cn. Its title and sign-in link identify it as the HappyShrimp policy; clarification remains open.

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

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

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.

Why it is included

Official HappyShrimp terms reserve model rights, grant limited service-use rights and prohibit extraction or reverse engineering of underlying parameters and weights. Alibaba identifies the model as its ATH-developed music system. No public-weight license is documented in the reviewed sources.
