Safety
Is it safe to delete Ollama models?
Short answer: yes for reclaiming disk. You lose local weights until you pull again. Prune never deletes blind.
What you actually delete
Ollama stores model blobs under ~/.ollama/models (Windows: %USERPROFILE%\.ollama\models). Individual tags can be 4–40 GB. Deleting them frees space immediately. Your prompts and app settings are not inside those weight files.
Manual cleanup
ollama list ollama rm mistral # or remove unused blobs from the models directory after confirming names
If you delete the folder wholesale, reinstall or ollama pull the models you still need.
When to keep them
- You are offline and need the model today.
- Re-download bandwidth or time is costly.
- A teammate’s automation expects a specific tag on disk.
FAQ
Does deleting Ollama models remove them forever?
The files leave your disk. Pull the model again with ollama pull and they come back. Chat history in the app is separate.
Where does Ollama store models?
Default is ~/.ollama/models on macOS/Linux and %USERPROFILE%\.ollama\models on Windows.
Will Prune delete models without asking?
No. Prune lists every path and only removes what you select.
