Local Inference – Run LLMs on Your Own Hardware (Guide and Forum)

A new hands-on guide teaches programmers how to run large language models on their own hardware, covering tools like Ollama, llama.cpp, vLLM, and Hugging Face's transformers. The guide explains local inference benefits including no API costs, privacy, offline capability, and low latency, with tutorials for setup, model selection, and performance tuning.

Local Inference Guide Run LLMs on your own hardware A deep, hands-on guide to local inference for programmers who know how to code but have never touched AI tooling. Every term is defined before it's used, and every tutorial section has commands you can actually run. What is "local inference"? Running a language model on hardware you control — laptop, workstation, or home server — instead of calling a hosted API. See Concepts & Glossary /concepts/ for the full breakdown. Why run models locally No API costs or rate limits — you pay in electricity and hardware, not per-token billing. Privacy — nothing leaves your machine. Offline capability — works with no network at all. Control — choose the exact model, quantization, and sampling behavior. Low latency — no network round-trip if embedded in a local app. Where to start New to all of this? Read top to bottom. Already know the vocabulary? Jump straight to a tutorial. Concepts & Glossary Start here Tokens, weights, quantization, KV cache, context window — every term defined once, clearly. Sizing Your Hardware The formula for figuring out what model size fits your GPU or RAM. Choosing a Tool Ollama vs. llama.cpp vs. vLLM vs. transformers — what each one is actually for. Ollama Tutorial 1 The fastest path from zero to a running local model. llama.cpp Tutorial 2 Build from source, quantize manually, run the raw inference engine. Python / transformers Tutorial 3 Full programmatic control using Hugging Face's library. vLLM Tutorial 4 High-throughput serving for many concurrent users. Building an App Tutorial 5 A portable streaming client that works against any of the above. Choosing a Model Qwen3, Gemma, Llama, DeepSeek, GLM — what's worth running in 2026. Performance & Troubleshooting GPU offloading, quantization tradeoffs, and fixes for common errors. Forum Ask questions and discuss local inference with other readers.
