借助 **Pydantic v2** 的这个特性，你的 API 文档会更**精确**，如果你有自动生成的客户端和 SDK，它们也会更精确，带来更好的**开发者体验**和一致性。🎉

## 不要分离 Schema { #do-not-separate-schemas }

当然，在某些情况下，你可能希望**输入和输出使用同一个 schema**。

最常见的情形是：你已经有一些自动生成的客户端代码/SDK，你暂时不想更新所有这些自动生成的客户端代码/SDK（也许未来会，但不是现在）。

这种情况下，你可以在 **FastAPI** 中通过参数 `separate_input_output_schemas=False` 禁用该特性。

Tests added here will be seen by all designers of language specific prompts.

Use as follows:

* Have a language specific prompt - `docs/{language code}/llm-prompt.md`.
* Do a fresh translation of this document into your desired target language (see e.g. the `translate-page` command of the `translate.py`). This will create the translation under `docs/{language code}/docs/_llm-test.md`.

...Python has a little special syntax for that.

Pass `*`, as the first parameter of the function.
