🐻 Gumini-1.5B-Base-i1-GGUF (구미니)

Built with Qwen

Model Description

GGUF quantized versions of GuminiResearch/Gumini-1.5B-Base for use with llama.cpp and compatible tools (Ollama, LM Studio, etc.).

All quantizations were created using importance matrix (imatrix) calibration for optimal quality preservation.

This is a BASE model, not instruction-tuned.
It produces text continuations rather than conversational responses.

Perplexity Comparison

PPL vs Size Trade-off

Recommended Quantizations

Quant	PPL	Size	PPL Δ	Quality	Use Case
Q8_0	8.50	1.5G	+0.02	Excellent	Maximum quality
Q6_K	8.52	1.2G	+0.04	Excellent	High quality
Q5_K_M	8.61	1.1G	+0.13	Excellent	Balanced (recommended)
Q4_K_M	8.72	956M	+0.24	Very Good	Size optimized
IQ4_XS	8.79	876M	+0.31	Very Good	imatrix 4-bit
IQ3_M	9.09	770M	+0.61	Good	Mobile/Edge

All Quantization Results

Comparison: 1B vs 1.5B

Model	Layers	Params	PPL (F16)	Improvement
Gumini 1B	10	1.08B	15.36	-
Gumini 1.5B	16	1.54B	8.48	45% better

The 1.5B model shows significant quality improvement with only 6 additional layers!

Usage

With llama.cpp

# Download
huggingface-cli download GuminiResearch/Gumini-1.5B-Base-i1-GGUF Gumini-1.5B-Base.i1-Q4_K_M.gguf

# Run
./llama-cli -m Gumini-1.5B-Base.i1-Q4_K_M.gguf -p "저는 구미니입니다." -n 100

With Ollama

echo 'FROM ./Gumini-1.5B-Base.i1-Q4_K_M.gguf' > Modelfile
ollama create gumini-1.5b -f Modelfile
ollama run gumini-1.5b

With LM Studio

Download any .gguf file from this repo
Import into LM Studio
Start generating!

Quantization Guide

Tips

Best quality: Use Q8_0 or Q6_K
Balanced: Use Q5_K_M or Q4_K_M
Mobile/Edge: Use IQ4_XS or IQ3_M
"i1" prefix: Indicates imatrix was used during quantization

Original Model

Gumini-1.5B (구미니) is a bilingual Korean-English base language model trained using the Inheritune methodology. Starting from Qwen 2.5 3B, the model progressively grew from 10 to 16 layers through 7 training stages.

Inheritune Progressive Layer Growing

Stage 0: 10 layers (1.08B) → 393M tokens
Stage 1: 11 layers (1.15B) → 393M tokens
Stage 2: 12 layers (1.23B) → 393M tokens
Stage 3: 13 layers (1.31B) → 393M tokens
Stage 4: 14 layers (1.39B) → 393M tokens
Stage 5: 15 layers (1.47B) → 393M tokens
Stage 6: 16 layers (1.54B) → 786M tokens ⭐
────────────────────────────────────────────
Total: 16 layers, 1.54B params, ~3.14B tokens

Training Data: 80% Korean, 20% English
