Running local LLMs has matured from a hobbyist experiment into a practical engineering choice. This guide covers hardware requirements (RAM/VRAM tables for 1B–30B+ models), installing Ollama and LM Studio, serving an OpenAI-compatible API locally, integrating with IDE extensions like Continue, and using the OpenAI Python/TypeScript SDKs with a simple base URL swap. Benchmark tables show tokens-per-second across Apple M3 Pro, RTX 4070/4090, and CPU-only setups. Model recommendations by use case (Qwen 3 8B for code, Llama 4 Scout for chat, Phi-4 14B for summarization) are included alongside common pitfalls: silent context-window truncation, quantization trade-offs (Q4_K_M vs Q5_K_M vs Q8_0), memory pressure, and security risks from exposing unauthenticated endpoints. Trends to watch include multimodal local models, QLoRA fine-tuning on consumer GPUs, OCI model registries, and WebGPU inference.
