One idea for a CAPTCHA that meets the criteria you have outlined is to use a combination of text and image recognition. For example, the CAPTCHA could present the user with a series of images and ask them to select all the images that contain a certain object or word. This could be difficult for an AI model to solve, as it would require both image and language processing capabilities.
Another idea is to use a CAPTCHA that involves solving a simple puzzle or task that requires some degree of human cognition and problem-solving. For example, the CAPTCHA could present the user with a set of shapes and ask them to rearrange them in a specific way, or it could ask the user to perform a simple arithmetic calculation. This type of CAPTCHA would be difficult for an AI model to solve as it would require the ability to understand and manipulate abstract concepts.
Another possibility is to use a CAPTCHA that involves asking the user to identify and select certain elements within a larger image, such as a specific object or text within a scene. This type of CAPTCHA would require the ability to understand and interpret the context of the image, which is a challenge for many AI models.
Overall, the key to creating a CAPTCHA that is both easy for humans to solve and difficult for AI models to crack is to design a task that requires some degree of human cognition and problem-solving, rather than relying solely on image or text recognition.
The first jdea is just literally what a CAPTCHA is, but the second sounds interesting, having the user play a game or solve some puzzle (minus the arithmetic), and third is also dumb.
I do think “image reasoning” could potentially be a viable captcha strategy.
A classic example is “find the time traveller” pictures, where there are modern objects that gives away who the time traveller is.
However, I think it shouldn’t be too difficult to teach an AI to identify “odd” objects in an image, unless each image has some unique trick, in which case we would need to create millions of such puzzles somehow. Maybe it could be made harder by having “red herrings” that might seem out of place but actually aren’t which might make the AI misunderstand part of the time.

If done such that nothing using current AI tech could do it, I don’t think 90% of people would be able to identify a time traveler.
