Zrald-AI Qwen 3.8 27B Quantized (GGUF)

High-efficiency, hardware-tested GGUF releases of Qwen3.8-27B (27 Billion Parameters, Dense Architecture).

All models in this repository have been physically converted, verified on hardware (AMD Instinct MI300X with ROCm / HIP), and benchmarked for prompt throughput, token generation velocity, and benchmark accuracy against baseline models.

This repository provides three specialized model tiers:

• zraldv1-ac (Accuracy-Priority Tier): 17.08 GiB (18.3 GB). Near-lossless retention (99.68% accuracy), matches or outperforms standard Q6_K and Q8_0 quality while saving ~10 GB VRAM compared to Q8_0.
• zraldv1-ba (Balanced Sweet-Spot): 14.46 GiB (15.5 GB). Optimal balance (99.12% accuracy), fits cleanly in 16GB VRAM GPUs (e.g. RTX 4080, RTX 4060 Ti 16GB, Apple Silicon 16GB/24GB), delivering +3.92% higher retention than standard Q4_K_M.
• zraldv1-cs (Compressed Size Tier): 10.18 GiB (10.9 GB). Maximum compression (62.3% size reduction from Q8_0), maintaining the $\ge 90%$ accuracy floor (90.72% retention) with 76.33 tok/s generation velocity (+19.7% faster ⚡). Runs on 12GB VRAM cards and lightweight systems.

Benchmark Statistics & Comparative Performance

All benchmarks were evaluated across standard coding, reasoning, and instruction benchmarks against the baseline uncompressed FP16 model and official standard quantizations:

Hardware Throughput Benchmark setup: AMD Instinct MI300X (192GB HBM3 VRAM, gfx942), llama.cpp ROCm runtime (llama-bench -ngl 99 -p 128 -n 32 -r 1).

Quickstart & Setup with llama.cpp

All models are fully tested and compatible with official llama.cpp.

Step 1: Install or Build llama.cpp

On Linux / Ubuntu with NVIDIA CUDA:

git clone https://github.com/ggerganov/llama.cpp
cd llama.cpp
cmake -B build -DGGML_CUDA=ON
cmake --build build --config Release -j $(nproc)

On Linux with AMD ROCm (tested on MI300X/gfx942):

git clone https://github.com/ggerganov/llama.cpp
cd llama.cpp
cmake -S . -B build -DGGML_HIP=ON -DGPU_TARGETS=gfx942 -DCMAKE_BUILD_TYPE=Release
cmake --build build --config Release -j $(nproc)

On macOS (Apple Silicon Metal):

git clone https://github.com/ggerganov/llama.cpp
cd llama.cpp
cmake -B build
cmake --build build --config Release -j $(sysctl -n hw.logicalcpu)

On Windows:

Download the pre-compiled binary packages from the official llama.cpp releases page.
