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.

The same model in two places

Ollama keeps weights as blobs named by their hash, so a model you also pulled through LM Studio or Hugging Face is a second full copy. Prune’s Duplicate Files finds these by contents and shows which tool holds each copy. If you remove the Ollama copy, Prune also removes the Ollama models that use it, so ollama list never shows a model it can no longer load. Both go to the Trash, and restoring them brings the model back.

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.
