My calculation (that is 3x 20x subscriptions) it will pay off after ~18.5 months, if I were to stop my subscriptions today. I will likely keep at least one though, so it's more like 27.5 months for a payoff. I am not doing it to save money though. I am doing it for security of supply. Constant quality - I know my model isn't getting lobotomized etc. - and open weight models mostly just lack very little behind. I'm sure I will have affordable, fast and efficient sol 5.6 capabilities with open weight models on my sparks within 12-18 months easily.
