# Run on ARM64

> Select ARM64 RealHW capacity from GitLab CI.

Source: https://docs.realhw.dev/guides/run-on-arm64/
Documentation index: https://docs.realhw.dev/llms.txt

Use a GitLab-compatible ARM64 tag for ARM jobs.

```yaml
arm64-tests:
  stage: test
  tags:
    - saas-linux-medium-arm64
  script:
    - test "$(uname -m)" = "aarch64"
    - ./test-arm64.sh
```

If you need only architecture matching and not a SaaS shape, use `arch:aarch64`.
