The Ollama version can be checked through the CLI and through the local API. Comparing both surfaces helps confirm that a shell command and a running server belong to the same install.

Use the CLI check after installs and updates, and the API check when debugging application connectivity. A stale background server can answer API requests even after a different CLI binary is installed earlier on PATH.

Record exact versions in task evidence when behavior depends on a recent feature, but keep article steps focused on the check itself.
