Apple Intelligence will work for the 9th gen iPad?

From this article:

Introducing Apple Intelligence for iPhone, iPad, and Mac - Apple

”Apple Intelligence will be available on iPhone 15 Pro, iPhone 15 Pro Max, and iPad and Mac with M1 and later, with Siri and device language set to U.S. English.”

Therefore the answer to your question is “No.”

apple does not really have a history of adding support for previously unsupported devices later on.

No one here knows what plans Apple may have for anything. Apple disclose their plans only when they are ready. Anyone who does know those plans will be prevented by non-disclosure agreements from commenting. Anyone commenting therefore does not know any more than you.

Once again, without a required Apple device, you will not get Apple Intelligence features on your device.

All details we know are available for public review here:

iOS 18 Preview - Apple

Note that Apple DOES place lots of substantive info in the end notes; so DO be sure to review those as well.

I have the same iPad with you, and I know that Apple intelligence doesn’t work with this iPad, because it has an A15 chip.

Would seem like it, we are all users like yourself we have no insight

Will it support in the future?

Probably not, considering the limit is performance, not recency. The iPad 9th Gen just doesn’t have enough power to run Apple Intelligence, and it won’t get any newer or more powerful.

So you can only get the iPadOS 18.1 update but not have Apple Intelligence?

Same here!
