Ollama in 2026: A Guide to Running AI Models Locally and Its Growing Ecosystem

Ollama is an open-source tool for running large language models locally, allowing users to download, manage and operate LLMs directly on personal computers. This reduces concerns about sending data to cloud services and incurring long-term costs. It supports multiple operating systems and hardware acceleration and integrates with Cursor and Claude Code, gradually becoming key infrastructure for local AI development.

By the first quarter of 2026, Ollama had recorded 52 million cumulative downloads. A recently published comprehensive guide covers installation, model comparisons, hardware requirements and tool integrations. It reflects how the ecosystem has evolved from a basic model launcher into a standard tool supporting AI software development, model testing and privacy-sensitive applications.
