Compiling models via the recommended entry points described in
[XLA](https://www.tensorflow.org/xla) and
[JAX](https://jax.readthedocs.io/en/latest/jax-101/02-jitting.html)
documentation should be safe, while some of the testing and debugging tools that
come with the compiler are not designed to be used with untrusted data and
should be used with caution when working with untrusted models.

## FastAPIのバージョンのアップグレード

アプリケーションにテストを加えるべきです。

**FastAPI** では非常に簡単に実現できます (Starletteのおかげで)。ドキュメントを確認して下さい: [テスト](../tutorial/testing.md){.internal-link target=_blank}

テストを加えた後で、**FastAPI** のバージョンをより最新のものにアップグレードし、テストを実行することで全てのコードが正常に動作するか確認できます。

全てが動作するか、修正を行った上で全てのテストを通過した場合、使用している`fastapi` のバージョンをより最新のバージョンに固定できます。
