Mureka AI: Kunlun Tech's Lyrics-First Music Model Family, Explained (Aug 2026)
Last updated August 7, 2026
Mureka is Kunlun Tech's lyrics-first AI music platform: write or import lyrics and the model composes the song around them. The family runs from mureka-7/o1 (the 'first thinking music reasoning model,' Jul 2025) to Mureka 9 and the press-reported V9.5, powered by MusiCoT chain-of-thought planning. Plans start at $8/month for 400 songs with commercial rights; training provenance is undisclosed. Mureka 9, 9 Instrumental, and 7.5 run inside invideo.
Updated August 2026
Mureka is Kunlun Tech's AI music platform, and its defining idea is lyrics-first generation: you write or import the lyrics, then the model composes the song around them — melody, arrangement, and vocals shaped to fit your words rather than the other way round. Behind the product is a fast-moving model line that Kunlun has iterated roughly every quarter, anchored by a distinctive technical bet: chain-of-thought reasoning applied to music. Its mureka-o1 model was billed as "the first thinking music reasoning model" when it shipped in July 2025 (Mureka platform announcement), and the platform claims nearly 10 million users worldwide (platform.mureka.ai, as of August 2026).
What is the Mureka model timeline?
The official API changelog (platform.mureka.ai/docs/en/changelog.html) gives clean dates for the API models; consumer "V" launches carry press-reported dates only, noted where they apply.
| Model | Date | What changed |
|---|---|---|
| mureka-7 + mureka-o1 | Jul 29, 2025 | o1 introduced as "the first thinking music reasoning model"; streaming mode, song recognize/extend APIs |
| mureka-7.5 | Sep 25, 2025 | Replaced mureka-7, "enhancing the effect of music generation" |
| mureka-7.6 + mureka-o2 | Dec 9, 2025 | Second-generation reasoning model |
| mureka-8 | Mar 2, 2026 | Consumer Mureka V8 launched earlier, reportedly Jan 28, 2026 (press coverage; not in the official changelog) |
| mureka-9 | Apr 9, 2026 | Consumer V9 reportedly unveiled in late March 2026; platform tagline: "More Lyric Control · Cleaner Mix · Faster Generation" |
| Mureka V9.5 | Jul 2026 (reported) | Adds "O3 reflective reasoning" and the MuCo creation agent, per Pandaily's coverage — treat details as press-sourced until Kunlun's changelog confirms them |
Note the version churn: consumer V-numbers and API model numbers run on separate tracks, a real source of confusion when comparing claims.
How does MusiCoT reasoning work?
Mureka's differentiation is MusiCoT — "Music Chain-of-Thought" — a CLAP-based technique in which the model plans the overall structure of a track before generating the audio, analogous to how reasoning LLMs think before answering (Mureka o1 write-up). In practice this is why Mureka handles the lyrics-first workflow well: a model that sketches song structure up front can place your verses, choruses, and hooks deliberately instead of drifting through them. The o1 → o2 → reported O3 line is Kunlun iterating on that reasoning layer, with V9.5's pitch — "AI music without the AI smell," per Pandaily — aimed squarely at the genericness that plagues AI-generated tracks.
Which Mureka variant should you pick?
Inside invideo's model picker the family appears as three entries:
| Picker entry | What it is | Pick it when |
|---|---|---|
| Mureka 9 | The current flagship song model — vocals from your lyrics, improved lyric control and mix quality | Full songs with vocals; anything lyrics-driven |
| Mureka 9 Instrumental | The same generation, no vocals | Background scores, beds under voiceover, intro/outro music |
| Mureka 7.5 | The Sep 2025 model that replaced mureka-7 | You liked a 7.5-era result and want consistency with it |
Default to Mureka 9 for songs and Mureka 9 Instrumental for anything that sits under dialogue — an instrumental-native generation beats stripping vocals later.
What can Mureka do beyond generating a song?
The API surface is unusually broad for a music vendor (docs index, changelog through Jul 2026):
- Stem separation in 5-stem and 12-stem variants, for pulling vocals, drums, or individual instruments out of a finished track.
- A fine-tuning API, so a catalog or brand-sound can be trained into a custom model.
- Voice cloning, available on the Pro plan.
- Music transcription, song extend, remix and lyrics-video endpoints, plus image/video soundtrack generation added between May and July 2026.
How much does Mureka cost?
Official plans from mureka.ai, as of August 2026:
| Plan | Price | Included |
|---|---|---|
| Basic | $8/month | 400 songs/month, MP3 downloads, commercial licensing |
| Pro | $24/month | 1,600 songs/month, WAV + stem downloads, voice cloning |
That works out to two cents a song on Basic — volume pricing aimed at creators who generate in bulk and keep the best takes. Per-song API pricing is not published on an accessible page, so treat any third-party API price figures as unverified.
Can you use Mureka music commercially?
Yes, contractually — and that qualifier is doing real work. Mureka's official line is that "every piece of music comes with full commercial rights and usage rights for unlimited applications" (mureka.ai), and commercial licensing is included from the $8 Basic plan up. What Kunlun does not publish, as of August 2026, is any claim that the models were trained only on licensed data, nor any disclosed deals with music rightsholders. V9-era marketing mentions "copyright compliance" improvements without specifics. The honest framing: your commercial rights are granted by contract with Mureka, but the training-data provenance behind those rights is undisclosed — a real distinction from vendors that market licensed-only training, and one to weigh for high-stakes client or broadcast work.
Mureka questions creators ask
Who makes Mureka?
Kunlun Tech, the Chinese technology company also known for the Opera browser acquisition and its Skywork/TianGong AI line. Mureka is its dedicated AI music platform, claiming nearly 10 million users as of August 2026.
What is the difference between Mureka V9 and mureka-9?
Two tracks of the same family: mureka-9 is the API model (released April 9, 2026, per the official changelog), while V9 is the consumer product release, reportedly unveiled in late March 2026. Capabilities align, but dates and naming differ — cite the changelog for anything precise.
How long can a Mureka song be?
Kunlun does not publish a maximum duration. Generations typically complete in 30–120 seconds of processing time; for exact length limits, the generate endpoints are the authority and third-party figures should not be trusted.
Can Mureka make instrumentals only?
Yes — instrumental generation is a first-class endpoint (/v1/instrumental/generate), not a post-processing trick, and it surfaces in invideo's picker as Mureka 9 Instrumental.
Does Mureka support stem downloads?
On the Pro plan ($24/month), downloads include WAV and stems, and the API offers dedicated 5-stem and 12-stem separation models for finer splits.
Where can you use Mureka?
Mureka 9, Mureka 9 Instrumental, and Mureka 7.5 all run natively in the Music tab of the invideo agent — which matters because a soundtrack rarely lives alone. The agent can generate the track from your lyrics and cut the visuals to it in the same conversation, drawing on the platform's 200+ models for the video side. The invideo AI models hub shows where the family sits in the wider lineup, and the music video maker workflow is the most direct route from a Mureka song to a finished video around it.
