| | # 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 |

| | ## ⚡ Hardware Performance |
| |
|
| | | Device | 27 Steps | 60 Steps | |
| | |---------------|----------|----------| |
| | | NVIDIA A100 | **30.50x** ⚡ | **14.10x** ⚡ | |
| | | RTX 4090 | **38.20x** � | **17.85x** � | |
| | | RTX 3090 | **15.30x** � | **8.12x** � | |
| | | M2 Max | **3.15x** � | **1.45x** � | |
| |
|
| | *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 |
| |
