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.
