Performance
| Metric | This model | Original model (Gemma-4-Harmonia-31B) |
|---|---|---|
| KL divergence | 0.0047 | 0 (by definition) |
| Refusals | ✅ 9/100 | ❌ 97/100 |
Lower refusals indicate fewer content restrictions, while lower KL divergence indicates more closeness to the original model's baseline. Higher refusals cause more rejections, objections, pushbacks, lecturing, censorship, softening and deflections.

HARMONIA
Gemini Word Salad Initialization
Harmonious Synthesis
Harmonia is a high-dimensional 31-billion parameter merge of Gemma 4. By executing a meticulous three-phase fusion of seven elite foundation and specialized models, Harmonia demonstrates a targeted approach to deep neural consolidation, minimizing regression while amplifying unique capability boundaries.
Instead of simple linear blending, which often degrades logical coherence and dilutes nuanced behavior, Harmonia was sculpted using a combination of mathematical projections, covariance activation matching, and surgical synaptic pruning. The model appears pretty solid so far.
Multi-Stage Fusion Protocol
The lineage of Harmonia is constructed systematically, passing through three isolated mathematical states to layer capabilities cleanly.
Nullspace Coherence Mapping
To anchor base capabilities, the primary Gemma-4-31B-Base is combined with the analytically rigorous GarnetV2-31B. Utilizing low-rank Singular Value Decomposition (SVD), the specialized donor features are projected entirely onto the mathematical null-space of the base weights. This prevents the creative delta vectors from distorting essential core intelligence, producing the stable platform clever-basename.
Surgical Synaptic Gating
Next, our newly anchored base is layered with the highly independent cognitive engines MeroMero-31B and Gembrain-31B. We apply Context-Aware Binary Selection (CABS) to execute structured, localized parameter gating. By enforcing precise structural pruning ratios (retaining optimal synapses in 16:32 and 11:33 ratios), we weave complex creative reasoning directly into the core matrix without causing neural interference. The result is the highly expressive clever-intname.
Covariance Activation Matching
In the final harmonization phase, the expressive clever-intname is combined with the narrative mastery of Equinox-31B, the creative depth of Fabled-Gemma4, and our primary conversational core Ortenzya-The-Creative-Wordsmith. Using data-free covariance estimation via task vectors, ACTMat reconstructs layer-wise input activation properties, solving for optimal projection weights in activation space. This resolves semantic alignment anomalies and delivers the unified output model.
