Ollama

AI

/dictionary/ollama

Definition

A wrapper around llama.cpp that makes running local LLMs a one-command operation. Pulls quantized GGUF models from a registry, exposes an HTTP API on localhost:11434, and handles model loading/unloading. The most common on-ramp to local inference in 2026.

  • Troubleshooting local LLMs (and how to keep up after this series)

    The full catalog of local-LLM failures: OOM, slow tok/s, garbage output, instruction drift, bad RAG hits, tool-call hallucination. Plus where to follow the field once you're on your own.

  • Fine-tuning a model locally

    When fine-tuning is actually the right call (it usually isn't) and how to pull off a LoRA run on a 16GB Mac, with a worked Llama 3.2 3B example.

  • Local agents and tool use

    Function calling on open models in 2026. Which ones actually work, why local agents break when they break, and the scaffolding that keeps them upright.

  • Local RAG and embeddings

    Build a working local RAG pipeline in about 30 lines using nomic-embed-text, Chroma, and Llama 3.2. And why running it on your own machine beats the cloud for personal notes.

  • Wiring a local LLM into the tools you already use

    How to point VS Code (Continue, Cline), web chat UIs (Open WebUI, LibreChat, Page Assist), and your own code at a local model using the OpenAI-compatible API. Swap cloud for local without rewriting anything.

  • Your first local LLM, start to finish

    Install Ollama, pull Llama 3.2 3B, chat with it, hit its API, and fix the five things that break on a first install. You finish with a working local LLM.

  • Every machine can run a local LLM (here's what fits)

    A per-tier guide to running local LLMs in 2026, from 8GB integrated graphics to a 192GB Mac Studio. Specific models, specific speeds, specific configs.

  • System requirements by OS for local LLMs

    What macOS, Linux, and Windows each need before you run a local LLM in 2026. Mac is the smoothest, Linux gives you the most knobs, and native Windows finally just works.

  • Streaming, throughput, and the KV cache

    Why TTFT and tok/s are different numbers, why streaming feels faster than it is, and the KV cache that makes the 1000th token cost about the same as the first.

  • The local-LLM vocabulary

    Parameters, B, dense vs MoE, base vs instruct, tokens, context windows, chat templates, GGUF, and quant suffixes. Read it once and any HuggingFace model card stops being scary.

  • What leaves your machine when you use AI

    What providers actually see, log, and keep when you call an LLM API in 2026. What "we don't train on your data" really means, how free and paid tiers differ, and when local is the only safe choice.

  • The runtimes: llama.cpp, Ollama, LM Studio

    llama.cpp is the engine. Ollama and LM Studio wrap it. What each one does, when to reach for which, and why the OpenAI-compatible APIs are mostly but not entirely interchangeable.

  • Why Apple Silicon punches above its weight on local LLMs

    Unified memory lets the GPU see all of RAM. Here's why that beats a discrete-GPU PC past 32B parameters, what fits in 16/32/64/128/192GB, and where Apple Silicon still loses.

  • What it takes to run a model on your own machine

    Why VRAM is the one number that decides whether a local LLM runs, what quantization really does to a model file, and the hardware ladder from an 8GB laptop to a 192GB workstation.

  • Where AI actually runs: cloud, local, edge

    When you use AI, a model file is sitting on a real machine. There are only three places it can be, and which one decides almost everything else.

  • Install the OpenAI SDK

    Install the OpenAI SDK for Python and Node, set your API key, and prove it works with a one-line chat call.

  • Install LM Studio

    Install LM Studio on macOS, Linux, and Windows, then flip on the local OpenAI-compatible server so any client library can talk to a model on your own machine.

  • Install llama.cpp

    Build llama.cpp from source with Metal or CUDA, then run a GGUF model with llama-cli. The closest thing to bare-metal local inference.

  • Install Ollama

    Get Ollama running on macOS, Linux, or Windows, pull your first model, and confirm it works with ollama list. The shortest path to a local LLM.
