Specifications
- Format: MLX
- Quantization: oQ3.5
- Method: Sensitivity-Aware Mixed Precision
- Target Platform: Apple Silicon
- Inference: MLX / oMLX
Unlike traditional uniform quantization, oQ dynamically allocates precision according to layer sensitivity, preserving higher precision for the most important weights while aggressively compressing less sensitive regions.
This provides an excellent balance between:
- Higher reasoning quality
- Better coding performance
- Lower memory usage
- Faster inference
- Excellent Apple Silicon efficiency
Recommended Settings
For the best reasoning performance:
temp: 0.6
top_p: 0.95
top_k: 20
min_p: 0
rep_penalty: 1.05
presence_penalty: 1.5
enable_thinking: true
These settings provide excellent performance across:
- Reasoning
- Mathematics
- Programming
- Tool Use
- Scientific Questions
- Agent Workflows
Example Usage
from mlx_lm import load, generate
model, tokenizer = load("YOUR_USERNAME/Qwythos-9B-oQ3.5")

}
]
prompt = tokenizer.apply_chat_template(
messages,
tokenize=False,
add_generation_prompt=True,
enable_thinking=True,
)
response = generate(
model,
tokenizer,

About oQ Quantization
oQ is a sensitivity-aware mixed-precision quantization technique designed to maximize model quality while significantly reducing memory usage.
Instead of quantizing every layer identically, oQ analyzes layer importance and preserves additional precision where it matters most.
Benefits include:
- Better reasoning retention
- Improved coding performance
- Higher mathematical accuracy
- Lower memory usage
- Faster inference
- Excellent Apple Silicon optimization
