# Qwopus3.5-9B-Coder-oQ4e-mtp

This model was quantized using [oQ](https://github.com/jundot/omlx) (oMLX v0.5.0) mixed-precision quantization.

## Quantization details

- **Model type**: qwen3_5
- **Bits**: 4
- **Group size**: 64
- **Format**: MLX safetensors

## Performance Benchmarks

> **Note**: Results are for reference only and may vary depending on hardware, software configuration, and workload.

### Environment
- **Hardware**: M5 MacBook Air 32GB
- **Inference Framework**: oMLX v0.5.0
- **Settings**:
  - Thinking: Disabled
  - Chat template parameter: enable_thinking=false (forced)
  - TurboQuant KV Cache: Disabled (if enable: reduces intelligence)

## Usage

```python
from mlx_lm import load, generate

# Load model
model, tokenizer = load("mlx-works/Qwopus3.5-9B-Coder-oQ4e-mtp")

# Generate text
prompt = "Hello, how are you?"
response = generate(model, tokenizer, prompt=prompt, max_tokens=100)
print(response)
```

## Notes

- This model uses Native MTP (Multi-Token Prediction) for improved speed
- Thinking mode is disabled for faster inference
