Ollama is an open-source platform for running and managing large language models entirely on your local machine. If local LLMs had a default choice in 2026, it would be Ollama. With over 150,000 GitHub stars and 500+ contributors, it removes the complexity of model formats, runtime backends, and configuration. Simply pull and run a model with one command. The platform bundles model weights, configuration, and data into single Modelfile packages and offers a CLI, REST API, and Python/JavaScript SDKs.

Frequently Asked Questions
What hardware do I need for Ollama?
For smaller models (7B), 8GB RAM is sufficient. For larger models like Llama 4 70B, you'll want a GPU with at least 16GB VRAM. Apple Silicon Macs work well. Ollama supports quantization to run larger models on limited hardware.
How do I use Ollama with OpenClaw?
Configure OpenClaw to use Ollama as its model provider by setting baseUrl to 'http://127.0.0.1:11434/v1' and specifying your model ID. The OpenAI-compatible API means no code changes needed.
Which models work best on Ollama?
For 2026, popular choices include llama4:8b for general use, qwen3:0.6b for limited hardware, deepseek-v3.2-exp:7b for reasoning, and glm-4.7-flash for coding. Check ollama.com/library for the full list.
Can Ollama run in Docker?
Yes, Ollama provides official Docker images. Use docker run -d -p 11434:11434 ollama/ollama to start, then docker exec -it <container> ollama run <model> to interact.
