Skywork AI launches Mureka V9 music generator
Skywork AI has launched Mureka V9, a music generation model that lands within one Elo point of market leader Suno V5.5, signaling a major shift in the competitive landscape for AI audio.

Skywork AI has released Mureka V9, a new music generation model that has debuted at the number two spot on both the Instrumental and Vocals leaderboards hosted by Artificial Analysis. In the instrumental category, the model has closed to within a single Elo point of the top-ranked Suno V5.5. The blind-vote arena rankings highlight this tight competition, where Suno V5.5 previously led the instrumental chart with an Elo of 1194, followed by Mureka V8 at 1167, Suno V5 at 1156, Lyria 3 Pro at 1123, and Suno V4.5 at 1087. On the vocals leaderboard, Suno V5.5 held an Elo of 1156, followed by Mureka V8 at 1144, Lyria 3 Pro at 1089, Suno V5 at 1086, and Suno V4.5 at 1077. Mureka V9 now displaces the older V8 model to sit directly behind Suno V5.5 on both charts.
Under the hood, Mureka V9 utilizes an architecture called MusiCoT, or Music Chain-of-Thought. Rather than generating audio in a step-by-step autoregressive manner, this system pre-plans the overall structural layout of a song before decoding the final audio tokens. This structural planning leads to much better coherence and arrangement over longer tracks. Additionally, the model offers a strong multilingual capability, supporting more than 10 languages including Chinese, Japanese, Korean, and Spanish, which allows it to outperform Suno on non-English tracks.
For music producers and sound designers, the model introduces a highly practical, DAW-native workflow. It supports MIDI export, up to 12-stem splitting, and features an integrated Ableton agent, providing integration options that competitors currently lack. Users can access the model through the Mureka application and API, or test it on the Artificial Analysis leaderboard. Skywork AI offers a free tier with approximately 50 daily credits, alongside a Pro tier priced at $9 per month. However, commercial adopters should note that Kunlun Tech, the parent company, faces an active copyright lawsuit, Attack the Sound LLC v. Kunlun Tech, filed in December 2025, though no liability has been established.
