I have been playing around with Veo/Whisk and it's easy to run out of free credits quickly. I'm not sure how comfortable I am using my normal Google account to pay for any more. How do you all pay (if at all) for AI or do you think it's a concern to begin with?

Usually credit card, although paypal does the trick sometimes too

If you're worried about people you know seeing what you're doing with the generators, a separate account would be smart, one unrelated to your primary email or social accounts.

For the paying aspect, it's probably not a big deal unless you're trying to hide the expense from someone. I just use Paypal for things that accept it, and my credit card for things that don't accept Paypal.

WHAT?

You mean people pay! I must be tight fisted!
There is still so much free stuff.

I can understand that paid access may be better quality.

With a card, reluctantly and out of frustration. Kling routinely goes from a hot-streak of great results to a constant stream of WTAF was that? 10 identical tasks will yield 10 completely unique results,
I had one earlier that was so preposterous I had to save it while LMFAO. Sometimes it seems more like a slot-machine than a video creator. I got the project done though.

Even some free AI accounts require a Google login. I have a second (wam) Google account, using a separate email address.

I do use my regular credit cards. All the sites and banks claim the merchants don't see your personal information. While I don't completely believe them, the alternative is to do without.

Whisk/Veo drew me in with their free credits. I tried paying with a gift card but you are probably right about credit cards.

You can try Gemini Pro for free for a month, which I'm currently doing. Descriptions of people--age, body type, ethnicity, hair, and clothing--are very accurately rendered, including colors. In complex situations, some specifications are ignored, such as the shape and appearance of banknotes.
Pies in terms of shape, size, and alignment still need improvement

I don't.

Only paid once to get more video generations on Hailoo, as the free trial lets you do about five before video fails to complete, even though you still have plenty of credits left (images are not subject to this dark pattern though). I'm not prepared to keep paying for this because it feels too much like gambling, throwing money at something for the repeated hit of seeing if it might come up with that one-more-step perfect generation. I would rather spend this on a video from a producer and model who need the work and are going to the effort of creating something, and that something having preview shots so I can see what I'm getting first. The other dark pattern is not allowing you to just buy x amount of credits but having to pay for a whole year of a subscription.
Happily perchance is still free and basically untroubled by NSFW restrictions.
