1. Executive Summary & Production Breakthrough

This repository presents the official TAP-DPQ v7 (Thouless-Anderson-Palmer Driven-Dissipative Post-Training Quantization v7) release of Liquid AI's LFM-2.5-8B-A1B.

LFM-2.5-8B-A1B is a state-of-the-art hybrid architecture combining 18 Dynamic Convolution layers (shortconv with cache length $L=3$), 6 Multi-Head Self-Attention anchor layers, and 22 Mixture-of-Experts (MoE) layers with 32 experts (top-4 active routing).

Key Architectural Invariants & TAP-DPQ v7 Guarantees:

1. Hurwitz Recurrent Core Stability:
   • The dynamic convolution temporal filtering kernels ($3 \times 2048$ per layer) govern the continuous-time dynamical state propagation. Quantizing these filters induces limit-cycle oscillations and exponential divergence.
   • TAP-DPQ v7 preserves 100% of dynamic convolution kernels (shortconv.conv) in pristine FP32, eliminating recurrent drift while adding $<0.4$ MB of overhead across the entire model.
2. MoE Router Gating Entropy Shield:
   • Router input projections (ffn_gate_inp) determine the sparse expert activation distribution across 32 experts. Low-bit quantization causes gating entropy collapse, starving specialized experts.
   • TAP-DPQ v7 pins router gating matrices in Q8_0 and router biases in FP32, preserving expert diversity and routing sharpness.
3. Tri-Domain CoT Transition Manifold ($\Omega^*$):
   • Calibrated using a 151,514-token transition-weighted corpus capturing:
     • 45% AST & Code Structures: class Solution boundary guards, Segment Trees with lazy propagation, Tarjan's SCC, CUDA WMMA recurrent kernels.
     • 35% Dense CoT Reasoning: Multi-step AIME competition proofs, GPQA Diamond condensed matter derivations, and 12,000-token continuous recurrent saturation traces.
     • 20% Linguistic & Multimodal Alignment: Spatial OCR bounding boxes, DocVQA coordinate grounding, and non-refusal safety probes.

2. Comprehensive Dual Benchmark Battery (Vanilla BF16 vs TAP-DPQ v7 Quants)

Evaluated on native sm_89 hardware using llama-server on port 8000. MATH-500 evaluated with SymPy Computer Algebra System (CAS) symbolic equivalence engine.
AIME 2026 evaluated across both Greedy decoding and Jesse & Archon's Min-P entropy steering (temp=0.6, min_p=0.05).
