Where are the saved presets stored?

[pelephant2]

When I save a preset (system prompt, sampling, tools) where is it stored? Please answer for Linux, Max, and Windows.

Not as a file per preset — they're rows in Studio's SQLite database, and the path is the same shape on all three platforms because Studio doesn't use the OS-specific config directories.

studio/backend/utils/paths/storage_roots.py:

def studio_db_path() -> Path:
    return studio_root() / "studio.db"

and studio_root() resolves in this order:

"""Unsloth install root.

Priority: UNSLOTH_STUDIO_HOME, then STUDIO_HOME alias, then sys.prefix
inference, then legacy ~/.unsloth/studio. UNSLOTH_STUDIO_HOME wins if
both are set (specific signal beats generic alias).
"""

with the final fallback being:

return Path.home() / ".unsloth" / "studio"

So unless you've set an override or are running from a venv Studio can infer a home from:

OS	Path
Linux	~/.unsloth/studio/studio.db
macOS	~/.unsloth/studio/studio.db
Windows	C:\Users\<you>\.unsloth\studio\studio.db

No ~/.config, no ~/Library/Application Support, no %APPDATA% — Path.home() is the only platform-dependent piece.

To find yours with certainty rather than guessing which branch applied, ask the code:

python -c "import sys; sys.path.insert(0,'studio/backend'); from utils.paths.storage_roots import studio_db_path; print(studio_db_path())"

If that prints something under sys.prefix instead of your home directory, the venv inference branch is what fired.

On the presets themselves: they aren't a table of their own. They go through get_app_setting / upsert_app_settings in storage/studio_db.py, i.e. they're stored as JSON blobs in the app-settings key/value store inside studio.db, with the custom ones under a customPresets key. Practical consequences:

• Backing up presets means copying studio.db — there's no small JSON file to grab. Copy the -wal and -shm siblings too if Studio is running, since the DB is opened in WAL mode.
• Editing them by hand means opening the DB and editing JSON inside a settings row, not editing a config file.
• Setting UNSLOTH_STUDIO_HOME moves everything at once (presets, auth, caches, outputs), not just presets, since every root in that module hangs off studio_root().
