# Gemma 3 Quantized Models
This repository contains W4A16 quantized versions of Google's Gemma 3 instruction-tuned models, making them more accessible for deployment on consumer hardware while maintaining good performance.
## Models
- **abhishekchohan/gemma-3-27b-it-quantized-W4A16**
- **abhishekchohan/gemma-3-12b-it-quantized-W4A16**

## Quantization Details
These models use W4A16 quantization via LLM Compressor:
- Weights quantized to 4-bit precision
- Activations use 16-bit precision
- Significantly reduced memory requirements
## Usage with vLLM
```bash
vllm serve abhishekchohan/gemma-3-{size}-it-quantized-W4A16 --chat-template templates/chat_template.jinja --enable-auto-tool-choice --tool-call-parser gemma --tool-parser-plugin tools/tool_parser.py
```
## License
These models are subject to the Gemma license. Users must acknowledge and accept the license terms before using the models.
