From what you said, you won’t accept such a product if it isn’t open source? Or at least, where you can choose the models and pay per use or something similar to that.
My guess is that big, powerful companies won’t use a pay-per-use Devin-like service because they just have so much people they can delegate tasks on that also use Cursor or the like; and startup companies that really need the product’d prefer a fixed rate like Cursor does.
Maybe they’ll actually use specialized agents for multiple tasks, but will also try to build their own solutions or sue frameworks rather than hire another company (like big companies that use Crew AI because it’s open source).
And are you ok with the quality that those full-fledged AI agents (like Devin) deliver? Do you have more pains that the single vendor dilemma?
