# PyTorch

**What:** The main toolkit AI apps are built on; runs models on Mac GPUs.

**Why:** Runs open models on your own hardware.

**Category:** Runtimes & inference · **Stack layer:** runtime

## Status

Catalog entry. Existence and repo metadata checked 2026-10-21 via the GitHub API. Install commands below are auto-extracted from the README and have NOT been executed or verified. Read the README before running anything; prefer a sandbox or venv.

## Install (unverified)

1. [macos-apple-silicon] source: Hugging Face blog 'MPS in PyTorch 2.15' (2026-10-20), release candidate; status: unverified, not executed

```bash
uv pip install torch==2.15.0 --index-url https://download.pytorch.org/whl/test/cpu
```

It uses pip, which needs a virtual environment (venv): a separate folder for one Python app.

## Verify

No verified check yet. Minimum: the install command exits 0 and the tool's own help/version flag runs (exact flag: see README).

## Rollback (unverified)

1. source: derived inverse of install command

```bash
uv pip uninstall torch
```
