Introduction of Harmonic-2B-GGUF
Model Details of Harmonic-2B-GGUF
Harmonic-2B-GGUF
GGUF quantizations of Harmonic-2B - a reasoning-focused draft model fine-tuned from Qwen 3.5 2B, designed for speculative decoding with the larger Harmonic models.
Available Quantizations
| Quantization | Size | Use Case |
|---|---|---|
| F16 | 3.6 GB | Full precision, no quality loss |
| Q8_0 | 1.9 GB | Near-lossless, recommended for most users |
| Q4_K_M | 1.2 GB | Smallest, great for edge/mobile |
Recommended Quantization
Q8_0 for most users - near-lossless quality, runs on basically anything.
Q4_K_M for maximum speed as a speculative decoding draft model.
Usage
Ollama
echo 'FROM ./Harmonic-2B-Q8_0.gguf' > Modelfile
ollama create harmonic-2b -f Modelfile
ollama run harmonic-2b
llama.cpp
./llama-cli -m Harmonic-2B-Q8_0.gguf -p "Solve this step by step:" -n 512
LM Studio
Download the GGUF file and load it directly in LM Studio.
