I'm starting a new project and need a fast API. For a Django (AI backend), is the asynchronous support in Django Ninja a significant advantage over the traditional Django Rest Framework when dealing with many concurrent AI requests?

If you are building a modern Django (AI backend), I strongly lean toward Django Ninja. The native async support is a game-changer when you're making I/O-bound calls to external AI APIs. Since Ninja uses Pydantic for schema validation, it's also much faster at serializing the large JSON objects often returned by LLMs. In a benchmark I ran for our internal AI tool, Ninja handled nearly 30% more concurrent requests than DRF because it wasn't blocking the event loop during network waits. Plus, the automatic Type Hinting makes your code much cleaner and easier to maintain for other developers on the team.
Donna, does the smaller ecosystem of Django Ninja make it harder to find third-party plugins compared to the massive library available for DRF?
DRF is still safer for enterprise projects where stability and "battle-tested" code are more important than the latest async features.
Sandra makes a good point, but for Django (AI backend) work, the performance gains of Pydantic and Async are hard to ignore. I've found Ninja to be very stable in production environments.
Thomas, that is the one downside. If you need complex features like automated documentation for specific auth patterns or specialized filtering plugins, DRF has everything. However, for a Django (AI backend), you usually just need fast endpoints to send and receive data, which Ninja excels at. Most "plugins" in AI are just Python libraries anyway, so you aren't missing out on much by choosing the faster, modern framework over the older, feature-heavy one.
