Ollama
Run open-weight models locally with one command. The lightweight daemon behind most local AI setups, serving Qwen3, Llama 4 Scout, gpt-oss and GLM through an OpenAI-compatible API.
About Ollama
Ollama is how most people run AI on their own hardware. One command pulls a model, another runs it, and an OpenAI-compatible endpoint appears on localhost for anything else to talk to. Ollama is free, open source and needs no account.
What is Ollama?
Ollama is a lightweight background daemon that manages downloading, quantising and serving open-weight language models locally, exposing them through an OpenAI-compatible HTTP API. That last detail is why it became infrastructure: any tool that speaks the OpenAI API — coding extensions, chat UIs, agent frameworks — can point at Ollama without modification. The model library has turned over substantially. Qwen3 is now the family most developers reach for, spanning 1.7B to 235B with 8B, 14B and 30B as the practical local sizes. Llama 4 Scout 17B is the best all-round locally runnable model thanks to its MoE architecture, Qwen3.6 27B is the coding leader, gpt-oss 20B has become the consensus choice for 16GB machines, and Phi-4 14B is the strongest option at 8GB VRAM.
Key Features
- One-command model management: Pull, run and swap models without touching quantisation settings or inference flags.
- OpenAI-compatible API: Drop-in local endpoint for existing tools and libraries.
- Broad model library: Qwen3, Llama 4, gpt-oss, Phi-4, GLM, DeepSeek and hundreds of community variants.
- Fully offline: No account, no telemetry requirement, no data leaving the machine.
- Cross-platform: macOS, Linux and Windows, with GPU acceleration where available.
Who Should Use Ollama?
Ollama suits developers who want a local model behind their editor, teams handling data that cannot leave the building, and anyone experimenting with open weights. It is also the standard backend for local coding setups: Ollama plus a quantised model plus a coding UI that can read your project files. The honest constraint is hardware — 8GB VRAM handles 7–8B models, 24GB is a realistic floor for 30B-class models, and 70B territory wants 40GB or more unless you quantise hard. If you want a graphical model browser and chat UI in the same app, LM Studio is the friendlier alternative.
Pricing
Ollama is free and open source. There is no subscription, no API key and no account. The only cost is hardware, and that cost is real: the difference between a frustrating local setup and a genuinely useful one is usually a GPU upgrade rather than a software choice.
Pros and Cons
| Pros | Cons |
|---|---|
| Free, open source, no account | Usable quality is gated by your GPU |
| Single command to pull and run any model | 30B+ models need 24GB VRAM or more |
| OpenAI-compatible API works with existing tools | Command-line first by design |
| Complete privacy — nothing leaves the machine | No hosted fallback for heavier work |
Bottom Line
Ollama is the default local model runner in 2026, and the open-weight models it serves — Qwen3, Llama 4 Scout, gpt-oss — are good enough that local AI is genuinely useful rather than merely private. Install it, pull Qwen3 at whatever size your GPU allows, and point your editor at localhost. If you want a GUI over the same idea, look at LM Studio or Jan.
