Qwen3-4B-Instruct-2507 — BitClass Mixed-Precision GGUF

Mixed-precision GGUF quantizations of Qwen3-4B-Instruct-2507 using learned per-tensor quantization profiles. Each tensor group receives the precision level that minimizes quality loss for its importance — more bits where they matter, fewer where they don't.

Seven precision levels from ultra-compact (3.0 bpw) to high quality (4.5 bpw). Low-BPW models use IQ types for better quality-per-bit; higher levels use KQ types for faster inference.

Models

File	Target BPW	Size	PPL ↓	Family
Qwen3-4B-Instruct-2507-MX-3.0bpw.gguf	3.0	1.72 GB	3.073	IQ
Qwen3-4B-Instruct-2507-MX-3.2bpw.gguf	3.2	1.79 GB	3.034	IQ
Qwen3-4B-Instruct-2507-MX-3.4bpw.gguf	3.4	1.88 GB	2.971	IQ
Qwen3-4B-Instruct-2507-MX-3.6bpw.gguf	3.6	2.02 GB	2.936	KQ
Qwen3-4B-Instruct-2507-MX-3.8bpw.gguf	3.8	2.03 GB	2.951	KQ
Qwen3-4B-Instruct-2507-MX-4.0bpw.gguf	4.0	2.01 GB	2.928	KQ
Qwen3-4B-Instruct-2507-MX-4.5bpw.gguf	4.5	2.47 GB	2.932	KQ

Target BPW is the planner's per-tensor bit budget (and the filename label). The actual whole-file BPW runs ~0.3–0.4 higher, because output/embedding tensors are kept at higher precision and GGUF carries metadata overhead — see the Size column for the real footprint.

Recommended: MX-3.4bpw for the best quality-to-size ratio. MX-3.0bpw for maximum compression. MX-4.0bpw for the highest quality in this ladder.

How It Compares

Model	BPW	Size	PPL ↓	Source
ByteShape KQ 3.34	3.34	1.69 GB	3.121	byteshape
★ Ours MX-3.0	3.0	1.72 GB	3.073	This repo
★ Ours MX-3.2	3.2	1.79 GB	3.034	This repo
Unsloth Q3_K_S	3.75	1.75 GB	3.007	unsloth
★ Ours MX-3.4	3.4	1.88 GB	2.971	This repo
★ Ours MX-3.6	3.6	2.02 GB	2.936	This repo
★ Ours MX-4.0	4.0	2.01 GB	2.928	This repo
Unsloth Q4_K_M	4.97	2.32 GB	2.956	unsloth
★ Ours MX-4.5	4.5	2.47 GB	2.932	This repo

All models benchmarked in the same session on identical hardware (NVIDIA GB10 ATOM, GPU) for fair comparison.

Key Results

Lower perplexity than ByteShape KQ 3.34: MX-3.0 (PPL 3.073) vs 3.121 — 1.5% better, at comparable size (1.72 vs 1.69 GB)
Lower perplexity than Unsloth Q3_K_S: MX-3.4 (PPL 2.971) vs 3.007 — 1.2% better, at 1.88 vs 1.75 GB
Lower perplexity than Unsloth Q4_K_M: MX-4.5 (PPL 2.932) vs 2.956 — 0.8% better, at 2.47 vs 2.32 GB

Benchmarking Details

All benchmarks run with llama.cpp (commit 406f4e3) on NVIDIA GB10 ATOM GPU with full offload (-ngl 999). Perplexity measured via llama-perplexity on a held-out evaluation set (20 chunks, 512 context). Throughput via llama-bench (512 prompt / 128 generation tokens). All models — ours, Unsloth, ByteShape — benchmarked in the same session.
