Qwen3.6-27B-YMQ-MTP-GGUF

Source Model: Qwen/Qwen3.6-27B

⚖️ An Architecture-Aware, AutoRound-Inspired Mixed Precision Layout

This repository features advanced, custom architecture-aware quantizations of Qwen3.6-27B processed directly from official raw BF16 source files using the custom YMQ-Compiler (v2.0) log-space framework.

These builds natively support parallel multi-token prediction (MTP) speculation engines and utilize high-context optimization parameters tailored for demanding code development API execution environments (such as RooCode/Aider).

📊 Quantization Preset Tier Details

Preset Tier Total Size Target Usage / Memory VRAM Profile Cognitive Real-World Coding Quality
XXS ~9.8 GB Absolute VRAM Squeeze / 12GB Card Lifeline Massive structural quantization noise. Best restricted to low-context, single-turn instructions. Fits 12GB cards with context cache breathing room.
XS ~11.0 GB Max budget squeeze / For the desperate High compression noise floor. Works for short scripts, prone to api calling degradation past 50k context size.
S ~12.2 GB Light workspace / Low-VRAM cache headroom Balanced economy. Great text parsing consistency, minor context layout fatigue on long coding passes.
M ~14.0 GB The Ultimate Coding Sweet Spot (Recommended) Elite logical stability. Complete logic clarity. It crushes standard industry 4-bit alternatives.
L ~17.0 GB Premium Single-GPU Processing / Heavy workloads Near-lossless instruction formatting. Pristine multi-turn architecture safety.
XL ~19.0 GB Maximum VRAM Fill / No Compromises Mathematical saturation ceiling. Full precision logic tracks for massive multi-file codebase operations.

📉 Perplexity Evaluation Metrics (WikiText-2)

The following scores demonstrate the mathematical quality preservation of the YMQ-Compiler log-space cluster analysis compared to standard linear quantization layouts. Tested natively via llama-perplexity at a 4096 context window.

Model Preset Variant File Size Perplexity Score Cognitive Calibration Verdict
XXS 9.8G 8.2515 Extreme VRAM economy boundary cliff.
XS 11G 7.6273 Isolated task profile fallback
S 12G 8.4656 Maximum budget compression cliff
M (Recommended) 14G 7.5295 🎯 The Ultimate Golden Target Balance
L 17G 8.0920 Mild network accumulation noise
XL 19G 7.9757 Diminishing returns / Structural bloat

💡 The Performance Breakthrough Explained

Notice how the M preset achieves a significantly lower perplexity score (lower is better) than the heavier L and XL files while being up to 5 Gigabytes smaller. This occurs because the YMQ-Compiler surgically protects the high-leverage 71k imatrix cognitive reasoning spikes with Q5_K and Q6_K shields, while aggressively compressing idle fact-storage tensors.


⚖️ YMQ vs. Uniform Quantization (The AutoRound Philosophy)

Standard quantization pipelines apply a blunt, uniform bit-depth across every single layer in a model. This wastes valuable VRAM on silent background layers while starving critical logic anchors of necessary precision.

The YMQ-Compiler implements a philosophy similar to advanced weight-tuning frameworks like Intel's AutoRound:

  • Targeted Bit Allocation: It strips bits away from low-leverage background tensors and automatically re-allocates that saved VRAM budget straight into full high-fidelity shields for the model's highest cognitive spikes and boundary pathways.
  • Instant Optimization: Instead of running heavy, days-long optimization training loops, YMQ achieves a highly accurate mixed-precision layout instantly by analyzing layer importance metrics in log-space.

The result is a custom mixed-precision portfolio that matches the low perplexity and high context stability of premium optimized quants (like AutoRound), while maintaining an ultra-lightweight, high-speed single-GPU cache footprint.


🛠️ The YMQ Compilation Architecture

Standard quantization pipelines treat network tensors like a flat dataset, applying destructive blanket low-bit compression to delicate tracking networks. The YMQ-Compiler solves high-context logic decay by parsing model files dynamically via an automated, multi-tiered protection matrix:

  1. Log-Space Gap Detection Clustering: Instead of flat percentage thresholds, the engine computes statistical cluster variances in log-space, successfully isolating intermediate logical reasoning spikes and elevating them to stable non-linear 4-bit (IQ4_XS) formats, while compressing idle fact-storage layers to aggressive 2-bit baselines.
  2. Fading Boundary Tapering: Recognizes the extreme fragility of initial token entry data vectors, forcing an input wave cushion (L00=IQ4_NLL01=IQ4_XSL02=IQ3_XXS) that gradually stabilizes parameters before hitting the fallback pools.
  3. Dedicated Gate Insulation: Hard-shields volatile parallel Transformer Multi-Head Attention and Mamba Linear State Space Model (SSM) routing paths, keeping context tracking perfectly noise-free.
  4. Asymmetric Vocabulary Shielding: Fixes tied-weight boundary errors by mapping the final logit classification exit heads to robust configurations to completely eliminate formatting loops and API tag leakage under deep contexts.
  5. Native Next-N Speculative Stripping: Processed with advanced pre-tokenizer stripping to ensure zero index offset drift or layer-shifting risks across hybrid configurations.
