MagicQuant GGUF Hybrids - Apriel 1.5 15b Thinker

(DEPRECIATED - Part of MagicQuant v1.0 which had significant flaws. Please utilize v2.0 which is production ready)

MagicQuant is an automated quantization, benchmarking, and evolutionary hybrid-GGUF search system for LLMs.

Each release includes models optimized to outperform standard baseline quants (Q8, Q6, Q5, Q4). If a baseline GGUF exists in this repo, the evolutionary engine couldn’t beat it. If a baseline is missing, it’s because a hybrid configuration outperformed it so completely that including the baseline would've been pointless.

These hybrid GGUFs are built to be as small, fast, and low-drift as possible while preserving model capability.

Notes:

• The HuggingFace hardware compatibility where it shows the bits is usually wrong. It doesn't understand hybrid mixes, so don't trust it.
• Naming scheme can be found on the MagicQuant Wiki.
• (tips) Less precision loss means less brain damage. More TPS means faster! Smaller is always better right?

Precision Loss Guide

• 0–0.1% → God-tier, scientifically exact
• 0.1–1% → True near-lossless, agent-ready
• 1–3% → Minimal loss, great for personal use
• 3–5% → Borderline, but still functional
• 5%+ → Toys, not tools, outside MagicQuant’s scope
