Can I try both for free?

Yes. Sign up with a Gmail, Outlook or work address and you start with $2 of free credit, no card needed. The credit works on every model, so you can give both the same prompt and keep the one you like. After that you pay per run, in dollars, with no subscription.

Do I need two accounts?

No. One Leap account runs Kling O3, Kling 3.0 and every other model, in the studio and through the API, from one balance in dollars.
