PhantomStep: The Ultimate Music Generation Foundation Model �

� Model Description

PhantomStep, crafted by GhostAI, is the pinnacle of open-source music generation. Building on the foundation of ACE-Step, PhantomStep redefines excellence with a reengineered diffusion-based architecture, GhostAI's proprietary Spectral Compression AutoEncoder (SCAE), and an optimized transformer backbone. Our model delivers unparalleled generation speed, musical coherence, and creative control, leaving competitors in the dust. �

Key Features:

• � 20× faster than LLM-based baselines (15s for 4-minute tracks on A100)
• � Flawless coherence in melody, harmony, and rhythm
• � Full-song generation with precise duration control
• � Multilingual text-to-music with enhanced vocal synthesis
• � Upcoming: Fine-grained style control and genre-specific optimizations

� Uses

Direct Use

PhantomStep empowers creators to:

• ✨ Craft original music from natural language prompts
• � Remix tracks with seamless style transfers
• ✍️ Edit lyrics and vocals with precision

Downstream Use

A foundation for innovation:

• �️ Advanced voice cloning
• � Genre-specific music generators (e.g., trap, classical, K-pop)
• �️ Professional music production suites
• � AI-driven creative assistants

Out-of-Scope Use

PhantomStep must not be used for:

• � Unauthorized reproduction of copyrighted material
• ⛔ Generating harmful or offensive content
• �️‍♂️ Misrepresenting AI-generated works as human creations

� How to Get Started

Dive into the code and demos:

• � Hugging Face Repository
• � Demo Space (Coming Soon)

⚡ Hardware Performance

RTF (Real-Time Factor) shown - higher values indicate faster generation

�️ Optimizations in Progress

PhantomStep is actively addressing the following limitations:

• � Output Consistency: Reducing "gacha-style" variability with stabilized random seeds and adaptive sampling.
• � Genre Performance: Enhanced training for niche genres (e.g., Chinese rap, avant-garde jazz).
• � Vocal Quality: Refined vocal synthesis for natural, expressive outputs.
• � Long-Form Coherence: Improved structural integrity for tracks >5 minutes.
• �️ Control Granularity: Introducing precise controls for tempo, instrumentation, and dynamics.

� Ethical Considerations

GhostAI commits to responsible AI:

• ✅ Ensure originality of generated works
• � Disclose AI involvement in outputs
• � Respect cultural nuances and intellectual property
• � Prohibit harmful or unethical content generation
