Run powerful large language models locally with a single command and private-by-default architecture.

Ollama is a highly efficient, open-source framework designed to democratize the deployment of large language models (LLMs) by enabling local execution on personal hardware. Built primarily on the llama.cpp backend, it streamlines the process of downloading, managing, and running state-of-the-art models like Llama 3, Mistral, and Phi-3 without relying on third-party cloud providers. As of 2026, Ollama has solidified its position as the standard local inference gateway for developers building privacy-centric RAG (Retrieval-Augmented Generation) applications. Its technical architecture utilizes advanced quantization techniques (GGUF) to maximize performance on consumer-grade GPUs (NVIDIA/CUDA, AMD/ROCm) and Apple Silicon (Metal). The tool provides a unified API that is largely compatible with the OpenAI specification, allowing for seamless 'drop-in' replacement of cloud-based endpoints with local instances. This makes it an essential component for organizations handling sensitive PII data or those operating in bandwidth-constrained environments where cloud latency is unacceptable.

Explore all tools that specialize in embeddings generation. This domain focus ensures Ollama delivers optimized results for this specific requirement.
A Dockerfile-inspired configuration format for packaging LLMs with system prompts, temperature settings, and top-k parameters.
Built-in /v1/chat/completions endpoint that mimics OpenAI's API structure.
Support for vision-language models like LLaVA that can process images and text simultaneously.
Efficient management of local blobs and layers to avoid redundant disk usage when sharing weights between models.
Direct optimization for local AI accelerators (Apple Neural Engine, Intel NPU) for 2026-era PCs.
Generation of vector embeddings (e.g., mxbai-embed-large) locally for vector databases.
Dynamic unloading of models to switch between multiple active LLMs based on VRAM availability.
Download the Ollama installer for your OS (macOS, Linux, or Windows).
Execute the installation script/package to register the background service.
Open terminal/command prompt and verify installation with 'ollama --version'.
Pull a model from the library using 'ollama pull llama3'.
