Ollama
Ollama is an open-source tool that enables users to download and run large language models (LLMs) locally on their own machines.
Ollama simplifies the process of running large language models (LLMs) and multimodal models directly on a user's computer, offering a privacy-first approach by keeping data local. It provides a command-line interface (CLI) and an API for easy interaction, model management, and customization, supporting a wide array of open-source models.
Ollama serves an important niche with impressive 166K GitHub stars and supports a wide range of local models, but the January 2026 security incident exposing 175,000 servers highlights significant governance challenges. Its position as a specialized tool for local AI deployment limits broader market impact despite strong technical capabilities.
