Overall fidelity and production quality of the generated music — covering dynamic range, frequency response, absence of artefacts, and broadcast-readiness. What each rating means here Strong Broadcast-quality output — clean dynamic range, rich frequency response, and no audible compression or generation artefacts. Moderate Good quality for consumer listening; some artefacts or limited dynamic range may be noticeable on high-quality speakers. Weak Noticeable compression artefacts, thin frequency response, or inconsistent quality — suitable mainly for demos or casual listening.
	Strong	Strong	Strong	Strong	Strong	Strong
Breadth of musical genres, moods, tempos, and instrumentation the model can produce with consistent quality from text prompts. What each rating means here Strong Spans many genres and moods with consistent quality — produces convincing output across pop, classical, electronic, jazz, and more. Moderate Covers mainstream genres well but shows weaker results for niche styles or complex mood combinations. Weak Limited genre coverage or strong default aesthetic that overrides style instructions — best for specific styles it was optimised for.
	Strong	Weak	Weak	Weak	Weak	Moderate
Quality and naturalness of AI-generated vocals — covering lyric coherence, melodic expressiveness, and accent/language diversity. What each rating means here Strong High-quality generated vocals with natural melodic expression, coherent lyrics, and good language diversity. Moderate Vocals are present and broadly understandable but may show inconsistency in pitch accuracy or lyric coherence. Weak Instrumental output only, or vocals are clearly synthetic with noticeable pitch or diction issues.
	Moderate	Weak	Strong	Strong	Strong	Moderate
Maximum length of music that can be generated in a single pass. Higher ceilings support full-length tracks without stitching. What each rating means here Strong Generates tracks of 2+ minutes in a single pass with consistent quality — suitable for full song production. Moderate Generates short clips (30–90 s) per pass; stitching or looping is needed for full tracks. Weak Very short outputs (< 30 s) per generation — significant post-production required for any full-length use case.
	Weak	Weak	Weak	—	—	Weak
Ability to export individual instrument or vocal tracks separately — enables post-production mixing and professional workflows. What each rating means here Strong Exports individual stems (vocals, drums, bass, instruments) enabling professional mixing and post-production workflows. Moderate Limited stem export available (e.g. vocals + instrumental split only) — not a full multi-track output. Weak No stem export — output is a single mixed audio file only.

Capability ratings are an expert synthesis across benchmarks, community evaluations, and provider documentation. “—” means no profile data for that dimension.
