Qwen3.8-2B — GGUF
Developed by Empero
GGUF quantizations of empero-ai/Qwen3.8-2B — a full-parameter distillation of Qwen3.8 2.4T A95B into the Qwen3.5-2B architecture, the smallest member of the family — 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 | Qwen3.5-2B (base) | Qwen3.8-2B | Δ |
|---|---:|---:|---:|
| mmlu (CoT, 57 subjects) | 0.283 | 0.548 | +0.265 |
| gsm8k_cot | 0.330 | 0.640 | +0.310 |
[!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 |
|---|---|---:|---|
| Qwen3.8-2B-Q4_K_M.gguf | Q4_K_M | 1.312 GB | Recommended. Best quality/size balance; runs on phones and SBCs. |
| Qwen3.8-2B-Q5_K_M.gguf | Q5_K_M | 1.455 GB | Higher quality at a modest size increase. |
| Qwen3.8-2B-Q6_K.gguf | Q6_K | 1.606 GB | Near-lossless. |
| Qwen3.8-2B-Q8_0.gguf | Q8_0 | 2.077 GB | Highest-quality quantization. |
| Qwen3.8-2B-BF16.gguf | BF16 | 3.897 GB | Full precision reference. |
Sizes are exact decimal GB from the uploaded files (1 GB = 1,000,000,000 bytes).
Where it runs
Practical weight-size-based guidance at modest context — the KV cache is the dominant cost at long context:
| Quant | Guidance |
|---|---|
| Q4_K_M / Q5_K_M | Phones, single-board computers, any modern laptop — CPU-only is entirely usable at this scale. |
| Q6_K / Q8_0 | Any 4 GB+ GPU, or CPU with 8 GB RAM. |
| BF16 | 6 GB+ GPU. |
Usage
llama.cpp
llama-cli -m Qwen3.8-2B-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 ` block, so allow a generous -n and strip the ...` 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/Qwen3.8-2B, a distillation of Qwen3.8 2.4T A95B into Qwen/Qwen3.5-2B trained on ~30,000 curated teacher traces from our internal Qwen3.8 distillation datasets. Weights are Apache-2.0, inherited from the Qwen base, shared as-is.
