 ## 2026-06-12 - [LLM Pipeline Caching & Truncation]
 **Learning:** Using `@lru_cache` on instance methods leads to memory leaks and hashability issues. Combining `@cached_property` for the heavy pipeline object with an internal cached function for results ensures both fast loading and efficient inference without reloading the model. Enabling `truncation=True` is critical for robustness against long inputs.
 **Action:** Use the per-instance caching pattern (cached property returning an inner decorated function) for all model inference services. Always enable truncation for LLM pipelines unless full context is strictly required.

+## 2026-06-13 - [LLM Inference Optimization with Quantization]
+**Learning:** Applying 8-bit dynamic quantization to PyTorch-based LLM pipelines (like DistilBERT) provides a significant latency reduction (~33%) on CPU environments. Using `torch.inference_mode()` further optimizes the hot path by disabling autograd overhead more effectively than `no_grad()`.
+**Action:** For CPU-bound LLM services, always consider 8-bit dynamic quantization of Linear layers and wrap inference in `torch.inference_mode()` for maximum efficiency.
