Covers foundation models and their concentration risks, fine-tuning strategies including LoRA and QLoRA, catastrophic forgetting and how modular adapters solve it, knowledge distillation for on-device deployment, retrieval-augmented generation (RAG) for grounding outputs in real documents, mixture-of-experts architecture, chain-of-thought prompting, and the real-world deployment challenges around GPU costs, latency, and enterprise privacy. The piece emphasizes that engineering ingenuity — not architectural breakthroughs — is what makes modern AI practical. ## Full article daily.dev links to this article rather than hosting it.
