CyberSecQwen-4B-AWQ

4-bit AWQ quantized version of CyberSecQwen-4B.

Quantization

Parameter	Value
Method	AWQ (group_size=128, zero_point=True)
Weight precision	4-bit
Compute dtype	float16
Calibration samples	320 CTI-Bench prompts (256 RCM + 64 MCQ, chat-template formatted)
Quantization tool	autoawq
Calibration hardware	Modal A100

CTI-Bench Evaluation

Evaluated under the Foundation-Sec-8B protocol:

• Temperature 0.3, max_tokens 512, concurrency 32
• 5 independent trials, zero-shot (no system prompt)
• vLLM v0.20.1 with awq_marlin kernel on Modal L4 GPU

Task	AWQ 4-bit	GGUF Q4_K_M	FP16 Reference
CTI-MCQ (2,500 items)	0.5921 ± 0.0083	0.5368 ± 0.0048	0.5868 ± 0.0029
CTI-RCM (1,000 items)	0.5814 ± 0.0025	0.6254 ± 0.0063	0.6664 ± 0.0023

Key findings:

• CTI-MCQ: AWQ 4-bit matches or slightly exceeds FP16 performance (+0.5 points). Better than GGUF Q4_K_M.
• CTI-RCM: AWQ 4-bit degrades by 8.5 percentage points vs FP16. GGUF Q4_K_M does better on this task (-4.1 pts).
• AWQ is best for MCQ (general language), GGUF is best for RCM (task-specific classification).
