Diverse Model Selection

This webapp is amazing, but I think it could be 1 step greater if its users could potentially utilize free, open-source alternatives to GPT-3 like GPT-J or GPT-Neo. Not completely sure if it would be costly on the website owner's end, but hopefully it could be cheaper overall? If it is expensive, maybe the owners could take advantage of advertising to pay for a sum of the costs, cheapening the prices on the user's ends - for example, displaying a video advert to the user while the model is processing or each time an input is fed into the resulting model. If hosting is limited, perhaps some code could be exported that the user can host locally or on a free service of their choice such as Glitch or Replit. Hope this is possible because it could definitely make the experience a lot more accessible!
