| Current documented model | V9.5 appears in the subscription page and Song API. | Music 3.0 is current publicly and recommended in the API reference. | These names do not establish which model Melogen has configured. |
| Lyrics and vocal controls | Song API supports lyrics and documented vocal/reference controls; model restrictions apply. | API supports lyrics and optional lyric generation; no comparative vocal score verified. | Run matched listening tests; this page declares no vocal-quality winner. |
| Instrumental generation | Current Instrumental API lists mureka-9.5. | Current Music API documents is_instrumental. | Both document non-vocal generation, subject to access and product surface. |
| Revision workflow | Extension, remix and region-editing APIs are documented. | Separate Lyrics API documents write/edit modes; equivalent audio-region editing was not verified. | Editing lyrics is not the same as editing a finished audio region. |
| Export documentation | Premier lists stems, MIDI, WAV and DAW-session downloads. API multitrack downloads are separately paid. | The Music API examples document 44.1 kHz / 256 kbps MP3. URL outputs expire in 24 hours. | Check exact export entitlement and retain your downloaded files. |
| Account availability | Public paid tiers list V9.5; API purchases are separate. | Paid Music/Lyrics APIs closed to new users on August 20, 2026; existing paying users may continue. Free variants are discontinued. | Confirm actual account access before choosing an integration. |
| Input and duration limits | Song API: lyrics up to 5,000 characters, prompt up to 1,024; up to three outputs per request. | Music 3.0 announcement describes songs up to five minutes; API standard prompt up to 2,000 characters and non-instrumental lyrics up to 3,500. | Vendor API limits are not automatically the limits of Melogen’s interface. |
| Consumer plans versus API rates | Observed Pro $8/month billed $96 annually; Premier $24/month billed $288 annually. No stable per-generation API rate verified. | No current, generally available Music API price for new users was verified; older price tables do not override the access notice. | No defensible across-product cost winner follows from these different billing models. |
| Commercial-use conditions | Paid consumer plans advertise rights; paid API calls have separate authorization under the API FAQ and terms. | Music creation terms require input rights and AI labeling. The open-weight Community License is a different license. | Check the actual service and license; do not treat an open-weight license as a hosted-service grant. |
| Practical evaluation | Consider for a documented revision or export requirement on the correct plan. | Consider for music or cover generation where account access is confirmed. | Choose by access, inputs, revision and output needs; then listen. |
