Qwen3-coder – 30B (Q4_K_S)
This is a quantized version (Q4_K_S) of the original:
Qwen3-coder – 30B (FP16)
Overview
- Base model: Qwen3-coder – 30B (FP16)
- Quantization: Q4_K_S
- License: Apache 2.0
- Format: Ollama model
- Type: Inference-optimized snapshot
Purpose
This model was created to:
- Reduce memory usage compared to FP16
- Improve inference speed on consumer GPUs
- Enable running a 24B model on more modest hardware
- Preserve a stable snapshot of the original model
Performance / Size
- Model footprint: ~17 GB (Q4_K_S)
- VRAM usage increases with context length due to KV cache
- Suitable for GPU inference on mid-to-high range consumer hardware
Hardware Notes (estimated)
20 GB VRAM GPU:
- Stable at ~4K context length in typical setups
~24 GB VRAM GPU :
- Likely supports ~6K–8K context depending on backend and KV cache settings (Not tested yet)
Trade-offs
Compared to FP16:
- ✔ Lower VRAM usage
- ✔ Faster inference
- ❌ Slight reduction in output quality and precision
Usage
Run locally:
ollama run LoPld/qwen3-coder-30b-a3b-q4_K_S
Reproducibility
Created from:
FROM qwen3-coder:30b-a3b-fp16
Quantized using:
ollama create <model> --quantize q4_K_S -f Modelfile
License
Original model: Apache 2.0
This quantized version inherits the same license terms.
Notes
- This is a frozen snapshot of the original model
- No upstream updates are expected for this version
- Intended for long-term local use and reproducibility
