Qwen3.8-4B — GGUF

Developed by Empero

GGUF quantizations of empero-ai/Qwen3.8-4B — a full-parameter distillation of Qwen3.8 2.4T A95B into the Qwen3.5-4B architecture — for llama.cpp, Ollama, LM Studio, Jan, KoboldCpp, and other stock GGUF runtimes.

This card is about choosing a file and running it. The capability writeup, full benchmark results, and best practices live on the main model card.

Headline results for the source model (CoT protocols, lm-evaluation-harness, identical settings base vs. student):

Task	Qwen3.5-4B (base)	Qwen3.8-4B	Δ
mmlu (CoT, 57 subjects)	0.354	0.553	+0.199
gsm8k_cot	0.850	0.785	−0.065

[!Note] Qwen3.5-class models are hybrids: three Gated DeltaNet layers for every full-attention layer. A recent llama.cpp build with Qwen3.5 / Gated DeltaNet support is required — older builds will fail to load the architecture.

Files

File	Quant	Size	Notes
Qwen3.8-4B-Q4_K_M.gguf	Q4_K_M	2.783 GB	Recommended. Best quality/size balance for most users.
Qwen3.8-4B-Q5_K_M.gguf	Q5_K_M	3.161 GB	Higher quality at a modest size increase.
Qwen3.8-4B-Q6_K.gguf	Q6_K	3.563 GB	Near-lossless.
Qwen3.8-4B-Q8_0.gguf	Q8_0	4.611 GB	Highest-quality quantization.
Qwen3.8-4B-BF16.gguf	BF16	8.666 GB	Full precision reference.

Sizes are exact decimal GB from the uploaded files (1 GB = 1,000,000,000 bytes).

What fits on a GPU?

Practical weight-size-based guidance at modest context — the KV cache is the dominant cost at long context and may require offload regardless of weight quant:

Quant	Guidance
Q4_K_M / Q5_K_M	Comfortable on 4–6 GB cards; strong CPU-only option as well.
Q6_K / Q8_0	6–8 GB recommended.
BF16	12 GB+.

Usage

llama.cpp

llama-cli -m Qwen3.8-4B-Q4_K_M.gguf \
  --temp 0.6 --top-p 0.95 --top-k 20 \
  -n 16384 -cnv

Use the built-in chat template (-cnv). The model is a reasoning model: every answer opens with a <think> block, so allow a generous -n and strip the <think>...</think> span for end users.

Ollama / LM Studio / Jan / KoboldCpp

Download the GGUF of your choice and load it directly; the chat template is embedded in the file. Recommended sampling: temperature=0.6, top_p=0.95, top_k=20.

Provenance & licensing

Quantizations of empero-ai/Qwen3.8-4B, a distillation of Qwen3.8 2.4T A95B into Qwen/Qwen3.5-4B trained on ~45,000 curated teacher traces from our internal Qwen3.8 distillation datasets. Weights are Apache-2.0, inherited from the Qwen base, shared as-is.
