Mureka O1 – A Music Reasoning Large Model Launched by Kunlun Tech

What is Mureka O1?

Mureka O1 is the world’s first music reasoning large model released by Kunlun Wanwei. It is the first music model in the world to introduce the “Chain of Thought” (CoT) technology. Mureka O1 incorporates thinking and self-criticism mechanisms into the reasoning process, significantly enhancing music quality, creative efficiency, and flexibility. It supports the generation of instrumental music and AI music creation in 10 languages, covering a wide range of music styles and emotional expressions. It also features distinctive functions such as song referencing and sound cloning. Mureka O1 provides open API services and model fine-tuning capabilities, enabling developers and music platforms to seamlessly integrate AI music generation capabilities.

The main functions of Mureka O1

• AI Lyrics Creation: Users can input themes or emotions, and Mureka O1 can generate corresponding lyrics to help users easily start their creative process.
• Style Control: Upload a reference audio to specify the song style, ensuring the work aligns with your artistic vision.
• Melody Recording: Users can record a melody motif, and the system will generate a complete accompaniment based on it, enhancing creation efficiency.
• Inspiration Stimulation: Provide a platform for users to freely express themselves, sparking creative inspiration.
• Generate Similar Songs: Upload a reference song, and Mureka O1 can quickly generate a song in a similar style.
• Voice Selection and Cloning: Users can specify the gender and tone of the singer, and upload their own voice to let the AI learn and replicate it, making the vocal part more personalized.
• Section Adjustment: Supports users in freely adjusting sections such as intro, verse, and chorus through tags.
• Extend or Regenerate Sections: After song creation is complete, users can extend the current track or regenerate unsatisfactory sections as needed.
• Low-Latency Music Generation: Mureka O1 achieves industry-leading low-latency music generation through deep optimization of AI infrastructure, delivering instant and high-quality user experiences.

The Technical Principle of Mureka O1

• Chain of Thought (CoT) Technology: Mureka O1 incorporates Chain of Thought technology, simulating the multi-step thinking process of humans. It breaks down complex music generation tasks into multiple steps for progressive reasoning. This enables the model to think more deeply and self-optimize during music generation, enhancing the quality and coherence of the music.
• Multi-round Reasoning: During the generation process, the model first creates a preliminary composition and then continuously reviews and optimizes the previous results in subsequent rounds, ultimately producing high-quality musical works.
• Structured Generation: Unlike traditional autoregressive models that generate audio step by step, Mureka O1 pre-generates the overall music structure before predicting fine-grained audio tokens. This significantly improves the structural coherence of the generated music and the precision of instrument arrangement.
• Based on the CLAP Model: Mureka O1 is built on the CLAP model, which enables high extensibility without the need for manual annotation, thereby enhancing the interpretability and quality of the generated music.
• Reinforcement Learning Optimization: During the training process, Mureka O1 employs reinforcement learning techniques to optimize model performance through continuous validation and error correction. For example, in music generation, the model self-optimizes based on a predefined reward function (e.g., music quality, style consistency, etc.).
• Policy Optimizer: A policy optimizer is used during the model training phase, incorporating techniques such as gradient compression, exploration and exploitation. These techniques help improve the training efficiency and generation quality of the model.
• Diverse Data Sources: Mureka O1’s training data includes synthetic data, human expert-annotated data, and Chain-of-Thought datasets (CoT Dataset). These diverse data sources provide rich learning materials for the model.
• Training Phase: During the training phase, the model is optimized through a reinforcement learning environment, while a reward function (e.g., validation and human feedback) is used to guide the learning process. This enables the model to better adapt to different types of music composition tasks.

How to Use Mureka O1
