What is Ollama? Nedir?
Ollama is an open-source tool that enables you to easily run large language models (LLMs) on your local computer.
Ollama was released in 2023 as a tool that greatly simplifies running large language models locally. What Docker does for containers, Ollama does for LLMs: it enables downloading and running models with a single command. Ollama supports popular open-source models like Llama 3, Mistral, Gemma, Phi, CodeLlama, and Vicuna. Model downloading, quantization, GPU acceleration, and memory management are handled automatically. A simple command like 'ollama run llama3' starts the model running. Ollama provides a REST API to facilitate integration of local models into applications. It offers OpenAI API-compatible endpoints, allowing existing OpenAI integrations to be easily redirected to local models. Custom model configurations can be created with Modelfile. Ollama is an ideal solution for scenarios requiring data privacy, environments without internet access, and those wanting to avoid API costs. It runs on macOS, Linux, and Windows. Projects like Open WebUI can add a web interface.
Use Cases
