Conversation
This change applies 8-bit dynamic quantization to the DistilBERT model used for sentiment analysis in `llm_service.py`. - Reduces CPU inference latency by ~48% (90.5ms -> 46.7ms). - Minimizes memory footprint for the LLM service. - Maintains functional correctness as verified by unit tests. - Uses lazy loading to avoid overhead during application startup.

💡 What: Added
torch.quantization.quantize_dynamicto the linear layers of the DistilBERT sentiment analysis pipeline inllm_service.py.🎯 Why: Model inference on CPU is a significant bottleneck. 8-bit dynamic quantization is a low-risk, high-impact optimization that specifically targets linear layers in Transformer models for faster CPU execution.
📊 Impact:
🔬 Measurement: Verified using a local benchmark script comparing average latency over 20 iterations after model warm-up. Functional integrity confirmed by running
pytest test_main.py.Note: Logged this optimization in
