## Other models { #other-models }

You can now get the current user directly in the *path operation functions* and deal with the security mechanisms at the **Dependency Injection** level, using `Depends`.

And you can use any model or data for the security requirements (in this case, a Pydantic model `User`).

And under the hood, Pydantic uses the same underlying Rust mechanisms as `orjson` to serialize to JSON, so you will already get the best performance with a response model.

## Default response class { #default-response-class }

It gives you all the flexibility to choose the ones that fit your project the best.

And you can use directly many well maintained and widely used packages like `pwdlib` and `PyJWT`, because **FastAPI** doesn't require any complex mechanisms to integrate external packages.

But it provides you the tools to simplify the process as much as possible without compromising flexibility, robustness, or security.

Colons are permitted as part of a bracketed IPv6 address, such as `http://[::1]/`.

Go 1.26 enabled two additional post-quantum key exchange mechanisms:
SecP256r1MLKEM768 and SecP384r1MLKEM1024. The default can be reverted using the
[`tlssecpmlkem` setting](/pkg/crypto/tls/#Config.CurvePreferences).

### One Load Balancer - Multiple Worker Containers { #one-load-balancer-multiple-worker-containers }

When working with **Kubernetes** or similar distributed container management systems, using their internal networking mechanisms would allow the single **load balancer** that is listening on the main **port** to transmit communication (requests) to possibly **multiple containers** running your app.

            <p>In addition to the traditional activation mechanisms (JDK version, OS properties,
            file existence, etc.), Maven now supports a powerful condition-based activation
            through the {@code condition} field. This new mechanism allows for more flexible
            and expressive profile activation rules.</p>
