🔬 Scientific Overview: Generalized Thouless-Anderson-Palmer (G-TAP v3)

Standard post-training quantization treats neural network weights as decoupled static matrices, solving local round-off errors via heuristic mean-field approximations. In modern architectures featuring Per-Layer Embeddings (PLE) and cross-layer Key-Value cache sharing—such as Google's Gemma 4 E4B—local quantization perturbations induce severe non-equilibrium cavity distortions across the layer hierarchy.

G-TAP v3 explicitly calculates and cancels the non-equilibrium Onsager reaction field:

$$\delta E_i = - \sum_{j \neq i} J_{ij} \langle s_j \rangle - \Gamma_i^{\text{Onsager}}$$

where the Onsager cavity term $\Gamma_i^{\text{Onsager}} = \chi_i \sum_j J_{ij}^2 \langle s_i \rangle$ compensates for the back-reaction of token activations on perturbed quantized weights. By conditioning the activation Hessian ($H = X X^T$) with thermodynamic cavity corrections over a 64-chunk sequence budget, G-TAP v3 eliminates residual gradient drift across Gemma 4's 42 decoder layers, preserving Per-Layer Embedding lookup fidelity and Grouped-Query Attention dynamics.
