It is quite a bloat. Llama3 7B is 4.7GB by itself, not counting all the dependencies and drivers. This can easily take 10+ GB of the drive. My Ollama setup takes about 30GB already. Given a single application (except games like COD that takes up 300GB), this is huge, almost the size of a clean OS install.
What FS you’re on? I’m using BTRFS and have the same problem. Simply because disk analyzer doesn’t read snapshots.
