Ollama makes it simple to download and run open-weight language models on a personal computer. Open-weight models are ones whose trained parameters are published for anyone to run. Its open-source tool, launched in 2023 under the MIT licence, works from the command line, through a local API and through desktop apps for macOS and Windows, and offers a curated library of models from the major open-model labs. It also offers cloud models, which run larger models on data-centre hardware through the same tools, sold through monthly plans.

Jeffrey Morgan and Michael Chiang founded the company. They had earlier helped build Docker Desktop after Docker bought their startup, Kitematic. Ollama went through Y Combinator and is based in San Francisco.

In July 2026 Ollama said it was used by 8.9 million developers a month and was present in 85% of Fortune 500 companies, with a team of 14 people. It raised a $65 million Series B that month, bringing total funding to $88 million. Its GitHub repository has more than 180,000 stars.
