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):

[!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.

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 <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/Qwen3.8-2B, 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.
