Ollama

Ollama is an open-source local LLM runtime that enables running large language models on personal hardware with a single command. The project is available at github.com/ollama/ollama, has approximately 172,000 GitHub stars, and was last updated in May 2026. It supports macOS (Apple Silicon via Metal), Linux, and Windows, with GPU acceleration for NVIDIA (CUDA) and AMD (ROCm).

Installing Ollama and running a model requires two commands:

curl -fsSL https://ollama.com/install.sh | sh
ollama run llama3

Ollama exposes an OpenAI-compatible REST API at localhost:11434, making it a drop-in local replacement for any application using the OpenAI SDK or LangChain/LlamaIndex/LiteLLM clients. An official Docker image (ollama/ollama) is available for containerised deployments. Python and JavaScript client libraries are maintained by the project.

The model library at ollama.com/library covers Llama 3, Gemma, Mistral, DeepSeek, Qwen, Kimi, MiniMax, Phi, and dozens of other models. Models are pulled on first use: ollama pull gemma3.

Radar Assessment

Placed in Tools / Assess / inner.

Ollama is the de facto standard for local LLM inference in developer workflows. At 172,000 stars it is one of the most widely adopted developer tools on GitHub. The OpenAI-compatible API is the key integration affordance: any project already using the OpenAI Python SDK can point base_url at a local Ollama instance to run entirely offline, without code changes. This makes it directly applicable to privacy-sensitive workloads, air-gapped environments, and cost-sensitive development iterations.

The inner position reflects zero-friction installation, the broadest model library of any local inference tool, and direct complementarity with other blips on this radar: LangChain local LLM integration, Open WebUI as a chat frontend, and any RAG pipeline that benefits from local embedding models.

Trial gate: Ollama serving as the inference backend for at least one real project (RAG pipeline, agent, or internal tool) with a non-trivial model (7B+ parameters) running in a local or self-hosted environment.
