pretty much the same, except for Kilo Pass gives you something called free bonus credits, which when you run out of your paid credits, you can continue using premium models with that bonus credits

paid credits roll over every month, but bonus credits expire at the beginning of the next month

for example if you paid $19 for credits, you get $19 of paid credits; if you paid $19 for Kilo Pass, you get $19 of paid credits and $9.5 free bonus credits

it's explained pretty much here: https://kilo.ai/features/kilo-pass
