Disclosure: I work at Clarifai.

Thanks for checking us out! Our demo may not fully represent what we have to offer, but you can see a sample response here with confidence numbers included (we call them probs): https://developer.clarifai.com/guide/tag#tag

In terms of labels, our "general" model has over 11,000 labels, and we also have specialized models with labels tailored for other purposes, including NSFW, travel, and food, among others.

Hope this helps
