Qwen3.8-9B — GGUF

Developed by Empero

GGUF quantizations of empero-ai/Qwen3.8-9B — a full-parameter distillation of Qwen3.8 2.4T A95B into the Qwen3.5-9B 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 Qwen3.5-9B (base) Qwen3.8-9B Δ
mmlu (CoT, 57 subjects) 0.546 0.751 +0.205
gsm8k_cot 0.885 0.870 −0.015

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
Qwen3.8-9B-Q4_K_M.gguf Q4_K_M 5.780 GB Recommended. Best quality/size balance for most users.
Qwen3.8-9B-Q5_K_M.gguf Q5_K_M 6.643 GB Higher quality, still fits an 8 GB card at short context.
Qwen3.8-9B-Q6_K.gguf Q6_K 7.559 GB Near-lossless.
Qwen3.8-9B-Q8_0.gguf Q8_0 9.786 GB Highest-quality quantization.
Qwen3.8-9B-BF16.gguf BF16 18.407 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 8–12 GB cards for everyday use.
Q6_K / Q8_0 12–16 GB recommended.
BF16 24 GB+.

Usage

llama.cpp

llama-cli -m Qwen3.8-9B-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/Qwen3.8-9B, a distillation of Qwen3.8 2.4T A95B into Qwen/Qwen3.5-9B trained on ~70,000 curated teacher traces from our internal Qwen3.8 distillation datasets. Weights are Apache-2.0, inherited from the Qwen base, shared as-is.
