Run open large language models privately, behind one API with a per VM credential and no default login.
Ollama is an open source runtime that downloads, quantizes and serves large language models such as Llama, Mistral, Gemma and Qwen behind a single REST API that is also OpenAI compatible. You pull a model with one command and call it from your own applications or the CLI.
The Ollama server is bound to loopback and fronted by an nginx TLS proxy that enforces HTTP Basic auth, so nothing is reachable without a credential. A fresh admin password and TLS certificate are generated on first boot into a root only file, so there is no default login. A small starter model is pre pulled so the API answers immediately, it runs on CPU and offloads to the GPU when one is present, and 24/7 cloudimg support plus a paired deploy guide are included.
