Executive Summary: The Rise of Specialized Small Language Models

← Series Hub | Next Chapter: Part 1: Hybrid AI Architecture → Prerequisite: Read the Series Hub for the overarching architectural curriculum and hardware requirements. Answer-first: Self-hosting specialized Small Language Models (1B–14B) on private vLLM infrastructure breaks even with cloud APIs at 8.5 million tokens daily. Beyond this threshold, self-hosted inference slashes operational expenditure by 95% to 98% and cuts P99 Time-to-First-Token latency from 1,850ms to sub-40ms while enforcing full data privacy under GDPR and HIPAA regulations. ...

Part 4: Knowledge Distillation from DeepSeek-R1 & Frontier Teachers

← Previous Chapter: Part 3: QLoRA & Axolotl Fine-Tuning | Series Hub | Next Chapter: Part 5: Preference Alignment: DPO, GRPO & KTO → Prerequisite: Read Part 3: QLoRA & Axolotl Fine-Tuning on Commodity GPUs for low-rank parameter tuning and memory budgeting. Answer-first: Distilling long Chain-of-Thought (CoT) reasoning traces from DeepSeek-R1 (671B MoE) into compact 1.5B–8B student models transfers complex deductive capability without hosting frontier hardware. Combining forward-backward token KL divergence with rejection sampling on verifiable tasks enables a 7B student model to recover 88% of teacher mathematical reasoning performance at 1/50th the operational cost. ...

Part 4: AI-Assisted Legacy Code Refactoring & Modernization

Answer-first: Using generative AI to refactor legacy code without safety nets is reckless, as LLMs frequently discard undocumented edge cases and subtle bug-for-bug dependencies. A bulletproof AI Modernization Framework combines Golden Master (Characterization) Testing, Tree-sitter AST dependency extraction, and two-phase reasoning validation (DeepSeek-R1 / Claude 3.7) to refactor multi-thousand-line monolithic modules with zero behavioral regressions. 📖 Bản tiếng Việt (Vietnamese Edition) | ← Series Hub | Next Chapter: Part 5: Autonomous Testing & QA Automation → ...
