P: Automatic image tagging

LR Desktop / Mobile / Web offers AI-based keyword search as its "Sensei" search.  But Adobe has never implemented it for LR Classic.

You might consider the Any Vision plugin, which uses Google Cloud Vision, or Excire Search. Any Vision uses Google Gemini AI, letting you write "prompts" that can generate keywords, descriptions, categorizations, and identify GPS locations.

I hope Lightroom can use AI to detect objects/themes/styles in photos and automatically add keywords.

A nice feature would be adding an object search feature in LrC.

How many times have we taken pics and there was no sign of the object name. This could apply to almost any object ie flower, car, vegetable . . .

Current process is exporting a JPG file and loading into Google in Lens search. 

Im LR Entwicklermodus kann das aktuelle Bild automatisch Verbessert werden.
kann diese Funktion auch auf alle markierten Bilder angewendet werden?

"All this presupposes that I have a GPU powerful enough to make local autotagging perform well."

Most common desktops and laptops are more than powerful enough to execute image classification models. In another context, I timed a popular open-source image-classification model:

https://community.adobe.com/t5/lightroom-classic-ideas/p-allow-users-to-disable-the-gpu-for-ai-masking/idc-p/13357752#M17183 

On a 2019 Intel Mac, it classified photos at about 111 photos/sec using its (now older) GPU, and at about 26 photos/sec not using the GPU.  That's more than fast enough and allows plenty of headroom to incorporate larger models.  Excire uses similar technology.

Training new models is much more compute-intensive in general. I don't have enough experience with that to comment on your desire to train on just your own photos. 

After a lot of thought I decided that I did not need Excire or any other tagging software that generatged generic tags such as "boat" or "mountain."  I already do a lot of manual tagging.  I tage faces of course, but I also tag subjects that are of interest to me and that sort of tagging is something that Excire can't do now, and probably won't do for a long time. 

As a Lightroom Classic user (only!) right now, what I need is AI that I can train on MY images only, and use that to tag new photos. And I want it to be Classic only, so I don't depend on an internet connection.

Also if Lightroom Classic did implement auto-tagging, I would have two concerns:

1. Do I even want to include more of the resulting tags?  Tag clutter is a concern for me.

2. How would the auto-tagging align with the keywords I have already created?  Would I need to revise those existing keywords to align with the auto-tagged equivalents.

All this presupposes that I have a GPU powerful enough to make local autotagging perform well.  And GPU boards now are $$$

Will it ever arrive?

I'm wondering whether it would be possible to extend LR's facial recognition to a general subject recognition for things such as "plants", "birds", "flowers" etc.

It would allow one to find things more quickly and greatly reduce the time spent on keywording. I 'm not after 100% accuracy but would happily to settle for 80-90%.

The Apple Photos app does an impressive job at this already.

Excire seems to be quite good and there are a number of plugins that can do this, but, if we can have it as a native feature it would be great!

This is already exist for LR CC, would be great if the Classic version could do automatic image tagging using Sensei tech, can we get this pretty please?
