# 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 |
|
|
|

|
## �️ 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 |
|
|
