VeriLoop-E2 · GSQ-RCO Mixed-Precision GGUF Suite

2-Bit & 3-Bit Quantizations with Multi-Token Prediction (MTP) & Vision Projector (`mmproj`)

Complete non-uniform GGUF quantization ladder of tsinghua-sigs-robot-lab/VeriLoop-E2 produced with GSQ-RCO per-tensor allocations.

Overview

This repository provides the complete GSQ-RCO mixed-precision GGUF quantization suite of VeriLoop-E2 (a 27B parameter dense multimodal model post-trained for robotic reasoning, trajectory verification, code, and mathematics).

Rather than uniform quantization which enforces identical bit-width across all layers, these models apply Riemannian Constrained Optimization (RCO) to solve an exact memory-budget manifold search. Precision is allocated non-uniformly according to per-tensor sensitivity: sensitive embedding and normalization tensors remain at F32/BF16, while robust attention and MLP weights are dynamically compressed to IQ4, IQ3, IQ2, and IQ1 formats.

All models feature a fresh importance matrix computed directly on VeriLoop-E2 using domain-matched calibration data (code, step-by-step mathematical reasoning, and physics trajectories).

Available Files & Full Precision Ladder

Each quantization tier is provided in both Standard and Monolithic MTP (-mtp) builds.

Key Benchmark Discoveries

Top-5 Token Parity ≥ 98.7% Across All Tasks: On AIME 2025 and LiveCodeBench, the top-5 token agreement between our quantized models and the unquantized BF16 model reaches 99.5%–100.0%. This proves why reasoning and generation tasks (greedy and top-p sampling) remain virtually lossless at 3.5 BPW.
Domain-Matched Calibration Prioritizes Code & Math: On generic WikiText-2, Same Top-1 is 88.75% for IQ3_XXS and 92.37% for IQ3_S. On AIME 2025, Top-1 match increases to 94.23% (IQ3_XXS) and 95.40% (IQ3_S). On LiveCodeBench, Top-1 match reaches 91.78% (IQ3_XXS) and 94.03% (IQ3_S).
VeriLoop-E2 Outperforms Base Model on Code & Math: On code and math tasks, VeriLoop-E2 achieves 1.78 PPL vs 2.29 PPL for the base Qwen3.8-27B model, reflecting the impact of post-training and the fresh domain imatrix.
TerminalBench 2.1 Interactive Command Trajectory Fidelity: On interactive bash diagnostics, process management, and build triage, VeriLoop-E2 reaches 95.84% Top-1 and 99.55% Top-5 agreement at IQ3_S, ensuring accurate multi-step CLI operations.
