PRISM-Shimmer V5 (Experimental)

Official checkpoint for the Shimmer architecture (PRISM with Complex Embeddings + Intrinsic Phase). This model uses Harmonic Embeddings instead of standard vector lookup tables to enable spectral alignment.

Architecture

• Encoder: 6-Layer PRISM (Spectral Gated Harmonic Convolution)
• Decoder: 6-Layer Transformer (RoPE + Flash Attention)
• Embedding: Complex-Valued Shimmer Embeddings (Real+Imag parts learned separately)

Usage

# Requires modeling_prism.py (included in repo)
from modeling_prism_gated import PRISMHybrid_RoPE
# Model definition is self-contained in the repo
