Qwen3.8 4B Distilled — GGUF

GGUF quantizations of Ma7ee7/Qwen3.8_4B_Distilled for use with llama.cpp, LM Studio, Ollama, Jan, and other GGUF-compatible applications.

Qwen3.8 4B Distilled is a 4-billion-parameter reasoning model created by distilling outputs from Qwen3.8-Max into the smaller Qwen3-4B-Thinking-2507 student model.

The full model was fine-tuned on r0b0tlab/qwen3.8-max-distillation-50k, a dataset of responses and reasoning traces generated by qwen3.8-max-preview.

Model Lineage and Naming

The name Qwen3.8 4B Distilled describes the model's distillation lineage:

• Teacher model: qwen3.8-max-preview
• Student/base model: Qwen/Qwen3-4B-Thinking-2507
• Full-precision fine-tune: Ma7ee7/Qwen3.8_4B_Distilled
• Resulting model size: Approximately 4 billion parameters
• Distillation dataset: r0b0tlab/qwen3.8-max-distillation-50k
• Distribution format: GGUF

This is a Qwen3-architecture student model distilled from Qwen3.8-Max-generated outputs.

The repository does not claim that the underlying architecture or original weights are from Qwen3.8-Max. Qwen3.8-Max is the teacher whose generated responses and reasoning traces were used as training targets for the 4B student.

This repository contains quantized conversions of that independently fine-tuned student model. It is not an official Qwen or Alibaba release.

Model Details

Available Quantizations

This repository includes the following quantization levels:

For most local users, Q4_K_M is the recommended starting point.

Use Q5_K_M when you have additional memory and want to retain more quality. Use Q8_0 when fidelity matters more than storage or RAM usage.

What “Distilled” Means Here

This model uses sequence-level knowledge distillation.

The smaller student was trained on complete responses produced by the larger teacher. This transfers parts of the teacher's behavior, reasoning patterns, solution structure, and response style without copying the teacher's architecture or weights.

Therefore:

• The architecture and original student weights come from Qwen3-4B-Thinking-2507.
• The distillation targets come from Qwen3.8-Max-generated outputs.
• The resulting checkpoint remains a 4B Qwen3 model.
• These GGUF files are quantized versions of that 4B distilled model.
• The model is not expected to reproduce the full capabilities of Qwen3.8-Max.

Quick Start with llama.cpp

A recent llama.cpp build can download and run a quantization directly from Hugging Face.

Ollama

Run the Q4_K_M quantization directly from Hugging Face:

ollama run hf.co/Ma7ee7/Qwen3.8_4B_Distilled_GGUF:Q4_K_M

Other available options:

ollama run hf.co/Ma7ee7/Qwen3.8_4B_Distilled_GGUF:Q5_K_M
ollama run hf.co/Ma7ee7/Qwen3.8_4B_Distilled_GGUF:Q8_0

Local Ollama Modelfile

After downloading a GGUF file, create a file named Modelfile:

FROM ./qwen3-4b-thinking-2507.Q4_K_M.gguf

PARAMETER temperature 0.6
PARAMETER top_p 0.95
PARAMETER top_k 20
PARAMETER repeat_penalty 1.05
PARAMETER num_ctx 32768

SYSTEM You are a helpful reasoning assistant. Think carefully and provide a clear final answer.

Create and run the model:

ollama create qwen3.8-4b-distilled -f Modelfile
ollama run qwen3.8-4b-distilled

If your downloaded GGUF has a different filename, replace the path after FROM with the actual local filename.

LM Studio

1. Open LM Studio.
2. Search for Ma7ee7/Qwen3.8_4B_Distilled_GGUF.
3. Select and download a quantization.
4. Load the model.
5. Confirm that the Qwen chat template is active.
6. Start with a context length of 16,384 or 32,768 tokens.
7. Increase the context length only when sufficient memory is available.

Suggested sampling settings:

Context Length

The model inherits its context configuration from Qwen3-4B-Thinking-2507. Actual usable context in a GGUF application depends on:

• Available system RAM
• Available VRAM
• Quantization level
• KV-cache precision
• GPU offloading configuration
• The llama.cpp or application build

A context length of 16K or 32K is a practical starting point for local use. Longer contexts can require substantially more memory because of KV-cache growth.

GPU Offloading

To offload as many layers as possible to the GPU:

llama-cli \
  -hf Ma7ee7/Qwen3.8_4B_Distilled_GGUF:Q4_K_M \
  --jinja \
  --conversation \
  -ngl 99 \
  -c 32768 \
  -n 4096

For CPU-only inference, omit -ngl 99 or set a smaller number of GPU-offloaded layers.

Recommended Generation Settings

For difficult mathematics, programming, or long-form reasoning, allow enough output tokens for the model to complete both its reasoning and final answer.

Thinking Output

The model inherits a thinking-oriented chat format from Qwen3-4B-Thinking-2507. Depending on the inference application and reasoning parser, visible reasoning may be displayed in a form similar to:

<think>
Reasoning process
</think>

Final answer

Some applications may hide the thinking section, place it in a collapsible panel, or display it separately from the final answer.

Distillation Dataset

The full model was trained on:

r0b0tlab/qwen3.8-max-distillation-50k

The dataset contains teacher-generated examples across areas including:

• Mathematics
• Programming
• General reasoning
• Scientific reasoning
• Instruction following
• Limited tool use

Teacher responses were generated by qwen3.8-max-preview. Visible <think>...</think> reasoning traces were retained when present in the dataset.

Intended Uses

This model is intended for local experimentation with:

• Mathematical reasoning
• Programming and code generation
• Logical reasoning
• Scientific question answering
• General instruction following
• Long-form problem solving
• Local conversational assistants
• Research into teacher-to-student distillation
• CPU and consumer-GPU inference

Limitations

• This is a quantized 4B student model and does not contain the complete capabilities of Qwen3.8-Max.
• Quantization may reduce quality relative to the full-precision model.
• Lower-bit quantizations may degrade more noticeably on difficult reasoning or programming tasks.
• Distillation transfers patterns from teacher-generated outputs; it does not copy the teacher's architecture or weights.
• Teacher-generated answers may contain factual, mathematical, or programming errors.
• Visible reasoning traces should not automatically be assumed to be correct.
• The model may hallucinate information or produce confidently incorrect answers.
• The training mixture is predominantly English.
• The training dataset includes examples originating from common evaluation benchmarks.
• Results on overlapping benchmarks may be contaminated and should not be treated as clean evaluations without additional controls.
• Outputs should be reviewed before use in high-stakes, medical, financial, legal, or security-sensitive settings.
