How to check the Ollama version

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.

1. Check the CLI version.

   $ ollama --version
   ollama version is 0.31.1

2. Check which binary the shell is using.

   $ command -v ollama
   /opt/homebrew/bin/ollama

3. Check the running API server version.

   $ curl -s http://localhost:11434/api/version
   {"version":"0.31.1"}

4. Restart the service or app if the CLI and API versions differ after an update.

   $ sudo systemctl restart ollama

5. Check the version again after restart.

   $ curl -s http://localhost:11434/api/version
   {"version":"0.31.1"}
